Everytime you said "this is the whey". I hear the mandalorian saying "This is the way". But in all seriousness. I did this the other night. Also made some (Gud) Jaggery. But when I extracted the casein. I split it up for different experiments.. One lump I added some diatemecaous earth to. And added a bit of calcium acetate. And some nearly pure China grade kaolin. I worked it all together. The casein seemed to mold well with it. Though my consistency wasnt perfect. Small cracks were unavoidable on molding. More kaolin probably would have rectified that. But after that I dropped the shaped lump in a saturated base solution. Of soda carbonate. And left it for an hour, or so. When I checked it later. While it was still submerged. I poked the to with my finger. It felt like a bouncy ball! The small cracks locked in place. I pushed as hard as I could with my finger. To try to split the piece on the tiny cracks. It was as strong as rubber. I put a bit more soda in solution. Which of course became oversaturated. And I noticed I've got a lot of precip today. Haven't checked it elasticity yet today though. Anyway if I can remember I'll post an update.. Oh and the other experiments I left casein unmixed. Dropped in a soda solution. And tossed in the fridge. Haven't checked those yet. The solution is so base. I have to glove up to me with it. And haven't got around to it yet. Excellent video though bud 👍.
Ok. So an update. I checked the rubber lump. It's still rubber. So I pulled it from solution. The precip is odd. The soda reacted in some way. The crystals formed are no longer sodium carbonate. Couldn't tell you what happened though. I'll look into possible reactions. The balls I threw Jarred in solution into the fridge.. Are very interesting as well. The solution froze solid. It's completely crystallized top to bottom. Kinda scared to touch it, and break the crystal matrix. But here goes...
Ok. So the balls floated. So when the solution froze the top halfs of the balls were left sticking out of solution. So I pressed on their tops. They are rubber like as well. Maybe a fraction less of elasticity. It's hard to tell. Because when I pressed them. It did not break the crystal matrix. It's almost like ice. And no my fridge does not freeze. I'm going to leave it out. See if the crystal lattice is temperature sensitive. The precip in my lump cup. Was not strong like this jar. But fragile. Anyway the crystal precip seems different in the jar. Though maybe my lump would have done the same in the fridge. If I remember I'll post an update about the jar experiment..
Mike, these are all great results. I am thrilled you are taking my little experiment to the next level. You may have a few interesting products at the end of this series. Keep us updated. I may want to pass on this in video for others, if you like.
@@GEOsustainable Thanks for the kind words. And yeah as an update. I've tried, and tried to stiffen the lump. In the oven, and microwave. It comes out a bit pliable. Then stiffens a little. But retains it's rubbery nature. But I am not happy with the color. It looks an off putting yellow. The Kaolin I believe is responsible for the inability to harden.. But, I'm going to do another experiment. And keep out all my last ingredients. Though I do want to do another experiment with the soda. As I read something interesting the other day. But, for my next experiment. I'm going a complete different direction. Which I'm hoping will go as I envision. As I'm hoping it will create a unique product. But first I need an ingredient that I do not have. I could probably order it online.. But, I'm going to make it myself. But I just harvested loads of acorns out front of my house. Got a big oak that's a bountiful giver. But, I'll be extracting the tannins. As they are known for binding to proteins causing them to precipitate. But it's a long story.. Which I'll elaborate upon if it goes as envisioned. Will take a few days, or more. In order for me to extract, and purify the tannins. Interesting side note. The ancient Egyptians knew of casein. Archeologists have found records of them extracting it from milk. And using it to make a tempera paint.. And I believe they also used it in other industries. That have yet to be fully understood. But anyway they actually found a 3000+ year old lump of egyptian "cheese". But I believe it wasn't meant to be cheese. When scientists studies it's composition. They were surprised to find no (Lactobacillus kefiranofaciens) or any other lactic acid bacteria. Which are the usual microbial signature. And defining characteristic of all kefir or kefir-like fermentation products. They also found it to be wholly made of casein. And, it was infected with brucella melitensis. Likely because of the way it was stored, and it had no lactic acid bacteria. Which likely means it was not meant to be cheese. They also found it to be impregnated with sodium carbonate in the trona phase. Which they attributed as being from leaching from the surrounding environment over the past few thousand years. I question that it was from leaching.. But, anyway it's certainly interesting. I'll try to remember to update you. After my my next experiment. Hopefully with some interesting results!
@Gypsy Six. You asked such a good question, and then deleted it. It is such a good question, I will answer it here. You asked if this formula can be thinned down with heat to pour it. To tell you, I have just discovered the thermoplastic nature of Casein. Plastic made from milk is almost a lost art. I was thinking the same thing resently. I plan to try to thin it with Ammonia and perhaps water during heating. What you saw here has never been done on RUclips. Stay tuned for a lot more work on this propety of Casein

When I got that fountain pen yesterday handmade from an very old galatith piece (and a nib from the 70's) I wasn't aware that where trying to know what galalith was would lead me :)It's an interesting subject to explore, first because you can do it yourself, but also for sustainable source of plastic. I guess it would also be an interesting application in countries that have to deal with milk overproduction.
@@GEOsustainable We know that plastic won't dissolve in water but what about bioplastic? Of course bioplastic made as above in the video will surely be biodegraded by bacteria. But still isn't the meaning of plastic that it won't dissolve in water?

Hey! I've got an idea that I would like to see you use in a future video! I've got a bulletproof way to make waterproof bioplastic gel, but it comes with 3 caveats: 1) The process is kinda tedious/ dangerous 2) it's semi- expensive. 3) It's very viscous/sticky! But all you need is 3 ingredients: Sodium sillicate (waterglass), Zinc chloride (ALOT of it), and cellulose (100% cotton clothing will do). Step 1: Boil water in a glass beaker/ acid proof beaker and mix in anywhere from 1 to 2 lbs of Zinc Chloride in the solution. Step 2: Boil down the solution to a point where it get's super syrup-y. You want to make the solution as saturated as possible so that the cotton can dissolve in it. (CAUTION: The more saturated it gets, the more Hydrochloric gas it will let off so be careful - Look up Zinc Chloride on wiki) Step 3: Place the glass beaker in a pot filled with water so you can give the Zinc Chloride solution a hot water bath. Put pieces of cotton in there and mix until they dissolve. If the Zinc Chloride solution turns black, it means it's too hot (burnt carbon). If it stays white, it's great! Keep doing until the cotton slows down dissolving/ stops dissolving. Good News. You made Cotton Acetate: a bioplastic. You're not finished yet. Gotta waterproof it. Step 4: Pour out some of the Zinc/Cellulose solution in seperate container and mix it in with some waterglass in a ratio of 1:1 or whatever ratio you want. (Ratio depends on waterglass, if sillica-rich waterglass, less flexible. If more sodium hydroxide, more flexible.) Step 5: Coat whatever clothing you wanna coat with the mixed Zinc Chloride/Cellulose/Waterglass solution. Let it air dry for a day or until it's not sticky no more. Step 6: Waterproof it/Vulcanize it by putting it in the oven at 200 F for 2-3 hours (nothing higher or it'll turn black). If it's still wet, redo Step 6. Step 7: Voila! Your clothes is 100% bioplastic-ally waterproof.
Thanks for letting me know what Waterglass is . I could never figure it out. Thanks. This looks like it came from the book on Industrial Uses of Casein. Brilliant comment. Thank you. I most certainly will put it on the list to try, and share it when I get questions from India. They are hugely searching for a way to do this.
I attempted this a few years back, I had a bit of a crazy idea to make a knife out of milk, it was fairly brittle since I didn't have a way to remove the water, but I now have a microwave so I can try again since the microwaving seemed to remove a lot of the excess water. (Especially since I have nothing but time with the outbreak)
a knife out of milk, this is so primitive ! im sure i can get a full metal gun from milk, as well as the biodegradable explosive powder for the bullets.
Outstanding. Can this hard bioplastic be used to make Castings with the silicone moulds you showed us how to make previously. This kind of looks like putty is there a pourable version that would make casting easier?
Hi, I am a student researcher and I'd like to email you some bio-plastic questions. I tried the email address from your about page but it didn't go through, please let me know if there is another way to reach you. and thanks for all the informative videos!
This looks like fun but is it any heat that softens it again, or just microwave? If you had something made of that stuff would it suffer from being in sunlight / sun heat? You wouldn't want to make eg a cup from it and have it suddenly soften from the heat. Also if you haven't a microwave is there an alternative thing that can be done please?
Any heat will work, I use the microwave because it is the most efficient method to soften it. I firms back up in seconds. Absolutely, sunlight will effect it, it is bioplastic and the sun helps it to decompose. It takes a few days in rain and then sun to decompose it. This video demonstrates bioplastic made from milk. There are other bioplastics, that I plan to make videos of, that can withstand heat and can be shaped into a cup. Great questions, thank you. Make no mistake, plastic from oil is on the way out. What we are doing here is beginning the research on bioplastics that can build a grassroots foundation for futher research.
I hear you can cure it with tannin - like from a strong tea mixture - to make it more resilient to breaking down. Check out Robert Murray-Smith for more videos on making this kind of plastic.
Fascinating! In recent years there has grown a small industry in making casein guitar picks (plectrums) to emulate the sound and feel of genuine tortoise shell. The best quality ones can run up to $50 a piece! I'm excited to try making one from milk. Are you able to comment on how clear casein is produced? I read in the book you mentioned that this is done by repeated alkali exposure. What is the practical approach to that? Also I'd love to know how manufacturers get the beautiful pearlescent effect. Is there a simple pearlizing agent that can be used? Thanks so much for this and any thoughts you have on these questions.
Great questions. There is someone that used my formula and is making jewelry with just those effects. I know about guitar picks, a few in the industry have commented on this video. It is spot on according to them. The rest I am afraid are likely trade secrets I am not privy to. Where we use food color, those in that industry are likely using dies and stains from animal. I would start there. Anyone in tanning could give you a little guidance I should think. All that aside, you can make high quality guitar picks using just what I show you here. Good Luck, and thank you for the questions. Oh, the pearlescent effect is from a patent, where they would hit a chuck of it with 2 dies heated to 2700F and stamp them. The original patent is online.
@@GEOsustainable Hmmm. Maybe we don't mean the same thing by pearlescent. I'm looking for something that gives that reflective swirling effect, much like some shampoo, that emulates the reflectiveness of real mother of pearl. I wonder if it's finely ground mica? Or maybe a fish scale product? I can easily imagine ways of kneading, or layering the galalith that will give beautiful swirling grain, but I'd love to find the pearling agent that's used in the best galalith and in celluloid. That's the stuff we often call mother-of-toilet-seat!
This formula is not waterproof. It will biodegrade in minutes once wet. Everything I used is natural except for Ammonia. You can replace that with an alkaline vegetable juice. Thank you for your kind words, I am thrilled you like. Keep in mind, for the most part, bioplastics won't be waterproof, and can only replace a portion of plastic made from LPG. It is best for one-use plastics. In a sustainable world, things that must be waterproof are put in glass and metal because they are HIGHLY recycled. Sustainability means to move away from a disposable society.
@@GEOsustainable couldn't agree more. although, I work in the agriculture sector which consumes massive amounts of plastics. a large portion of the applications requires waterproofness from the plastics, as well as durability in outdoor conditions and we are trying to find sustainable alternatives for those plastics. would love to share more about the project if you find that interesting (:
Hello, thanks for the video, it's explained very well! I have a few questions about casein and would be very happy if you can answer them .. (the internet doesn't know nothing) ***** -The rinsed, still malleable casein does not set under water? Not even in salt water solution? Right? -Which high degrees, is the thermal deformation point of the casein? Is it possible to put thus Point down with hodrophobic substances? For example castor oil (Ricinus) -I found very different density data on casein 1.17 g / cm³ / 1.25 g / cm³ / 1.45 g / cm³ what is correct or what does this depend on? -I have read that casein and cellulose acetate are soluble with benzyl alcohol but I cannot find any information on how much dissolves in how much .. do you have a list for it? Also whether the benzyl alcohol should be warmed up (?) To absorb (more) casein? - Casein is a polymer almost all polymers can be mixed. Do you know with which wax and oils a permanent good and soft/ waxy connection is made? Between 68 °F to 176 °F -Is there a calculated coefficient of expansion for casein? ***** I know these are some questions, but I think you have already done some experiments with this substance and can therefore give good information. Thank you and best regards!
I can answer none of these questions with specificity, but I can make a few observations. There are no easy answers, you will need to experiment and develop for yourself. I do not like to let students fast track learning and give answers, so again, do the work and you will know for sure. I would think if you leave Casein submersed in water, it will turn into a not so tasty milk. Density of Casein is dependant on the manufacturing process. All those numbers are very close to each other, and most likely of no importance. I use isopropyl alcohol to remove fat and sugar. I no longer need to do that, as I buy Casein powder that is analyzed to contain less than .2%. Thermal expansion of Casein can be 3 to 4 times the volume. I have included the link to the book I work from, in many of my videos. This should be your starting point as it is the only significant source on Casein uses in industry. Beyond that, here is a link I think can give you more. bionumbers.hms.harvard.edu/bionumber.aspx?id=103880
Man oh man This sounds really friggin' awesome, now if only we could get enough milk to replace all of them petroleum plastics... This does work with spoiled milk, right? Only it'd be mighty smelly... Or would the vinegar drown the smell of spoiled milk? How does it hold up to wear and repeated use? Have you guys tried any of those standardised tests that they perform on factory-produced materials to see if they hold up?
Correct. I have given you insight on how to manufacture bio-based thermoplastic. Take this and start a company to replace fossil fuel plastic with bioplastics. My goal is to share my knowledge, tips and tricks as well as define manufacturing processes for others to take and run with.
I have a certain type of grip for my sentures that is made ofnthis type of plastic but it also has either veg glycerin or pg or and oil i it makes it plyable when heated in warm warter
Great question! The body builder supplement has a small amount of Soy to keep the Casein from clumping. This will need extracting with Alcohol washes as I demonstrated in one of my videos on Casein. It is not easy to do. Strangely enough, the Soy added, according to the FDA, is small enough to not report. My information about the additive comes from a maker of the Casein powder. Fat Free Milk is the best option. Another option is ordinary Powered Milk. These, you will need precipitate the Casein.
I just read, due to a change in "school lunches" being in the news (1/17/20) that there was 13 gallons of milk thrown away per day at one school... Seems like this could be a source for making these "plastic" biodegradable shopping bags...
These videos are so awesome, new sub here! I tried this with some expired (not really expired but tastes terrible and undrinkable) lactose free (Fairlife brand) whole milk but after heating 1/2 cup of the milk for 1 min and adding 1/4 cup vinegar a little at a time, all I got were little chunks and it looked nothing like yours. Can you please tell me what I did wrong? I literally have 4 bottles of expired milk I don’t want to throw away if I can make something crafty with it. Was hoping to make some flexible texture plates (like embossing folders). I have my sample drying outside but it’s still pretty pitiful 🤣 I also mixed in about 2 teaspoons of glycerin hoping it would be flexible. Does the milk have to be fat free? You are such a blessing with your knowledge base, thank you!
Sure thing. Old milk is fine, and prefered. Heat the milk ONLY to warm, not hot. Add vinegar all at once. The reaction is immediate after a very quick and gentle stir. But some folks leave it overnight to curdle. It is best if the milk is fat free. Rinse in alcohol if the curds are slimy. Casein plastic is very hard to prevent cracking unless you add a plasticizer. What I show in the videos will get you going, but it takes a lot of time to learn to work with Casein. Good Luck and I am thrilled you like my series.
@@GEOsustainable hey thanks for answering so quickly. It wasn’t slimy at all, just tiny little chunks that wouldn’t clump together that looked more powdery. Adding the glycerin after rinsing and squeezing out just made it crack like crazy when I tried to roll it out and press things into it. I didn’t try the alcohol yet, I thought you said water rinsing but maybe that will work better. I am binge watching your channel 😱 as an artist, the milk paint and history behind it I’ve never heard of in my 60 years. Keep up the great work and hopefully I can figure out what to do with all this milk 😄
once formed would this be food grade plastic? dam man i just realised this was 2019. i hope this Casein plastic is food grade and injection mouldable as those are the key requirements for it to replace meat tray plastic. this would be a game changer. of coarse you would not want to use milk that could feed people as the carbon issues of cows comes into question.
Awesome. You are the 3rd person to make guitar picks from my recipe. I am just thrilled.

@@GEOsustainable Galalith is an interesting product. I was thinking to add PVA glue to milk and curdle it with vinegar or citric acid to make a harder material. What do you think of PVA use?
@ I have never tried it. It sounds interesting. To use it instead of Glycerine? Let me know how it goes. I may want to share your idea.
3 года назад
@@GEOsustainable Yes, glycerin makes a pliable end product whereas (Wikipedia says on Galalith page) formaldehyde makes it harder. So I will be using PVA glue instead.
I did. You didn't appear to treat the casein with formaldehyde at any point, you just moulded it right away. That leaves you with plain moulded casein, not galalith. Seems to be a common confusion on YT. If you could show the process of a proper treament, the thing which I'm after, that'd be great.
@@bencesarosi7718 You should watch my continuing series on the subject, as it is impossible to present everything in one. I do not use Formaldehyde...I present sustainable options to it. In this video, I present a long forgotten attribute on the thermoplastic properties of Casein, which seem to be overlooked by everyone. I will adjust the title here, but, I present the sustainable alternative to Formaldehyde in another video, for making Galalith. And, I don't know of any video on YT that presents Galalith, other than the one I have.

I most certainly will put it on the list to try, and share it when I get questions from India. They are hugely searching for a way to do this.
I attempted this a few years back, I had a bit of a crazy idea to make a knife out of milk, it was fairly brittle since I didn't have a way to remove the water, but I now have a microwave so I can try again since the microwaving seemed to remove a lot of the excess water. (Especially since I have nothing but time with the outbreak)
Worth a try, and yep, plenty of time to try some new things.
a knife out of milk, this is so primitive ! im sure i can get a full metal gun from milk, as well as the biodegradable explosive powder for the bullets.
Outstanding. Can this hard bioplastic be used to make Castings with the silicone moulds you showed us how to make previously. This kind of looks like putty is there a pourable version that would make casting easier?
You can adjust the formula. I have other videos on the subject that may work better for your needs
Hi, I am a student researcher and I'd like to email you some bio-plastic questions. I tried the email address from your about page but it didn't go through, please let me know if there is another way to reach you. and thanks for all the informative videos!
I would say check the spelling and try again. You are most welcome.
This looks like fun but is it any heat that softens it again, or just microwave? If you had something made of that stuff would it suffer from being in sunlight / sun heat?
You wouldn't want to make eg a cup from it and have it suddenly soften from the heat.
Also if you haven't a microwave is there an alternative thing that can be done please?
Any heat will work, I use the microwave because it is the most efficient method to soften it. I firms back up in seconds. Absolutely, sunlight will effect it, it is bioplastic and the sun helps it to decompose. It takes a few days in rain and then sun to decompose it. This video demonstrates bioplastic made from milk. There are other bioplastics, that I plan to make videos of, that can withstand heat and can be shaped into a cup. Great questions, thank you. Make no mistake, plastic from oil is on the way out. What we are doing here is beginning the research on bioplastics that can build a grassroots foundation for futher research.
I hear you can cure it with tannin - like from a strong tea mixture - to make it more resilient to breaking down. Check out Robert Murray-Smith for more videos on making this kind of plastic.
Fascinating! In recent years there has grown a small industry in making casein guitar picks (plectrums) to emulate the sound and feel of genuine tortoise shell. The best quality ones can run up to $50 a piece! I'm excited to try making one from milk. Are you able to comment on how clear casein is produced? I read in the book you mentioned that this is done by repeated alkali exposure. What is the practical approach to that? Also I'd love to know how manufacturers get the beautiful pearlescent effect. Is there a simple pearlizing agent that can be used? Thanks so much for this and any thoughts you have on these questions.
Great questions. There is someone that used my formula and is making jewelry with just those effects.
I know about guitar picks, a few in the industry have commented on this video. It is spot on according to them.
The rest I am afraid are likely trade secrets I am not privy to.
Where we use food color, those in that industry are likely using dies and stains from animal. I would start there.
Anyone in tanning could give you a little guidance I should think.
All that aside, you can make high quality guitar picks using just what I show you here.
Good Luck, and thank you for the questions.
Oh, the pearlescent effect is from a patent, where they would hit a chuck of it with 2 dies heated to 2700F and stamp them. The original patent is online.
@@GEOsustainable Hmmm. Maybe we don't mean the same thing by pearlescent. I'm looking for something that gives that reflective swirling effect, much like some shampoo, that emulates the reflectiveness of real mother of pearl. I wonder if it's finely ground mica? Or maybe a fish scale product? I can easily imagine ways of kneading, or layering the galalith that will give beautiful swirling grain, but I'd love to find the pearling agent that's used in the best galalith and in celluloid. That's the stuff we often call mother-of-toilet-seat!
love your work!
how can it be made waterproof from natural or non-toxic materials?
also, how fast would it biodegrade if placed outdoors?
This formula is not waterproof. It will biodegrade in minutes once wet. Everything I used is natural except for Ammonia. You can replace that with an alkaline vegetable juice.
Thank you for your kind words, I am thrilled you like.
Keep in mind, for the most part, bioplastics won't be waterproof, and can only replace a portion of plastic made from LPG. It is best for one-use plastics.
In a sustainable world, things that must be waterproof are put in glass and metal because they are HIGHLY recycled.
Sustainability means to move away from a disposable society.
@@GEOsustainable couldn't agree more.
although, I work in the agriculture sector which consumes massive amounts of plastics. a large portion of the applications requires waterproofness from the plastics, as well as durability in outdoor conditions and we are trying to find sustainable alternatives for those plastics.
would love to share more about the project if you find that interesting (:
Aside from formaldehyde, what else can we use to make it waterproof?
let us know. We are still working on that. I use tea.
@Kevin Corapi but tannic acid is sort of hydrophilic
Hello, thanks for the video, it's explained very well!
I have a few questions about casein and would be very happy if you can answer them .. (the internet doesn't know nothing)
*****
-The rinsed, still malleable casein does not set under water? Not even in salt water solution? Right?
-Which high degrees, is the thermal deformation point of the casein? Is it possible to put thus Point down with hodrophobic substances? For example castor oil (Ricinus)
-I found very different density data on casein 1.17 g / cm³ / 1.25 g / cm³ / 1.45 g / cm³ what is correct or what does this depend on?
-I have read that casein and cellulose acetate are soluble with benzyl alcohol but I cannot find any information on how much dissolves in how much .. do you have a list for it? Also whether the benzyl alcohol should be warmed up (?) To absorb (more) casein?
- Casein is a polymer almost all polymers can be mixed. Do you know with which wax and oils a permanent good and soft/ waxy connection is made? Between 68 °F to 176 °F
-Is there a calculated coefficient of expansion for casein?
*****
I know these are some questions, but I think you have already done some experiments with this substance and can therefore give good information.
Thank you and best regards!
I can answer none of these questions with specificity, but I can make a few observations. There are no easy answers, you will need to experiment and develop for yourself. I do not like to let students fast track learning and give answers, so again, do the work and you will know for sure. I would think if you leave Casein submersed in water, it will turn into a not so tasty milk. Density of Casein is dependant on the manufacturing process. All those numbers are very close to each other, and most likely of no importance. I use isopropyl alcohol to remove fat and sugar. I no longer need to do that, as I buy Casein powder that is analyzed to contain less than .2%. Thermal expansion of Casein can be 3 to 4 times the volume. I have included the link to the book I work from, in many of my videos. This should be your starting point as it is the only significant source on Casein uses in industry. Beyond that, here is a link I think can give you more. bionumbers.hms.harvard.edu/bionumber.aspx?id=103880
@@GEOsustainable
thanks for the answers and the link too. i will explore akso materials myself and see what works best for my ideas.
please do you know how to make a cling film from casein (what are the steps)
Man oh man
This sounds really friggin' awesome, now if only we could get enough milk to replace all of them petroleum plastics...
This does work with spoiled milk, right? Only it'd be mighty smelly... Or would the vinegar drown the smell of spoiled milk?
How does it hold up to wear and repeated use? Have you guys tried any of those standardised tests that they perform on factory-produced materials to see if they hold up?
True, true. Pretty sure it will hold up to all those tests, this is not new. Milk was used in plastic making 100 years ago, before oil.
@@GEOsustainable I have no doubts that it will, I was just curious as to what exactly it's like.
Would powered milk work? Love this video!!
Yes Absolutely powdered milk will work, many folks use it just as it is. I am so glad you like. Thank you.
I think I just saw you demonstrate the production of a thermoplastic. Is that right?
Correct. I have given you insight on how to manufacture bio-based thermoplastic. Take this and start a company to replace fossil fuel plastic with bioplastics. My goal is to share my knowledge, tips and tricks as well as define manufacturing processes for others to take and run with.
I have a certain type of grip for my sentures that is made ofnthis type of plastic but it also has either veg glycerin or pg or and oil i it makes it plyable when heated in warm warter
I will never see mozzarella cheese the same way. :0
I love fresh motz. Stay tuned. I am expanding this formula where I make some cool home compostable plastic products.
Hi, Is there a way to contact you about these casein videos? I tried to email you but they bounced back.
I got your email. I will answer you there.
when i did this the casein had the consistency of cottage cheese instead of being nice and rubbery, does anyone know why this is?
Yes, you have to use warm water. The more hot, the more elastic is will become. Keep working it in the water.
Does this process work with commercial powdered casein?
Great question!
The body builder supplement has a small amount of Soy to keep the Casein from clumping. This will need extracting with Alcohol washes as I demonstrated in one of my videos on Casein. It is not easy to do.
Strangely enough, the Soy added, according to the FDA, is small enough to not report. My information about the additive comes from a maker of the Casein powder.
Fat Free Milk is the best option.
Another option is ordinary Powered Milk.
These, you will need precipitate the Casein.
@@GEOsustainable ooooh, today i learned a thing ^^
Sir your video is very interesting and helpful 👍
Sir how do we create biodegradable pet water bottle. Please make video on that
I got you covered. Here is my video n just that subject. ruclips.net/video/cq6yqe2QBiQ/видео.html
hi I really enjoy your video and I wanna ask if this is edible or safe like I can use it to make utensils? Thank you in advance!
Yes, you can use this formula to make utensils, but I would not eat it, it has no flavor.
@@GEOsustainable Thank you very much and I hope you have a good day ahead of you!
dear sir i want to know how to make starch based bioplastic shopping bags on large scale
We can explore that via email. Look below one of my videos for my email.
I just read, due to a change in "school lunches" being in the news (1/17/20) that there was 13 gallons of milk thrown away per day at one school... Seems like this could be a source for making these "plastic" biodegradable shopping bags...
@@freakinlyrical9086 I donot think it would be suitable. You need about 100mpa tensile strength for plastic bag
These videos are so awesome, new sub here! I tried this with some expired (not really expired but tastes terrible and undrinkable) lactose free (Fairlife brand) whole milk but after heating 1/2 cup of the milk for 1 min and adding 1/4 cup vinegar a little at a time, all I got were little chunks and it looked nothing like yours. Can you please tell me what I did wrong? I literally have 4 bottles of expired milk I don’t want to throw away if I can make something crafty with it. Was hoping to make some flexible texture plates (like embossing folders). I have my sample drying outside but it’s still pretty pitiful 🤣 I also mixed in about 2 teaspoons of glycerin hoping it would be flexible. Does the milk have to be fat free? You are such a blessing with your knowledge base, thank you!
Sure thing. Old milk is fine, and prefered. Heat the milk ONLY to warm, not hot. Add vinegar all at once. The reaction is immediate after a very quick and gentle stir. But some folks leave it overnight to curdle. It is best if the milk is fat free. Rinse in alcohol if the curds are slimy.
Casein plastic is very hard to prevent cracking unless you add a plasticizer.
What I show in the videos will get you going, but it takes a lot of time to learn to work with Casein. Good Luck and I am thrilled you like my series.
@@GEOsustainable hey thanks for answering so quickly. It wasn’t slimy at all, just tiny little chunks that wouldn’t clump together that looked more powdery. Adding the glycerin after rinsing and squeezing out just made it crack like crazy when I tried to roll it out and press things into it. I didn’t try the alcohol yet, I thought you said water rinsing but maybe that will work better. I am binge watching your channel 😱 as an artist, the milk paint and history behind it I’ve never heard of in my 60 years. Keep up the great work and hopefully I can figure out what to do with all this milk 😄
once formed would this be food grade plastic? dam man i just realised this was 2019. i hope this Casein plastic is food grade and injection mouldable as those are the key requirements for it to replace meat tray plastic. this would be a game changer. of coarse you would not want to use milk that could feed people as the carbon issues of cows comes into question.
Yes
Is this waterproof? And Do these plastic bio degrade?
It can be made waterproof. It will biodegrade.
I am making some guitar picks soon
Awesome. You are the 3rd person to make guitar picks from my recipe. I am just thrilled.
@@GEOsustainable Galalith is an interesting product. I was thinking to add PVA glue to milk and curdle it with vinegar or citric acid to make a harder material. What do you think of PVA use?
@ I have never tried it. It sounds interesting. To use it instead of Glycerine? Let me know how it goes. I may want to share your idea.
@@GEOsustainable Yes, glycerin makes a pliable end product whereas (Wikipedia says on Galalith page) formaldehyde makes it harder. So I will be using PVA glue instead.
Can you make a pla on corn starch?
I don't understand your question.
I need to contact you privately. I need to discuss with you a way to extend your Knowledge to Africa let me know how i can get to you.
Of course. Contact me at martin20krunner@yahoo.com
Okay, so you made some dry casein. But where's the galalith?
Finish watching the video.
I did. You didn't appear to treat the casein with formaldehyde at any point, you just moulded it right away. That leaves you with plain moulded casein, not galalith. Seems to be a common confusion on YT.
If you could show the process of a proper treament, the thing which I'm after, that'd be great.
@@bencesarosi7718 You should watch my continuing series on the subject, as it is impossible to present everything in one. I do not use Formaldehyde...I present sustainable options to it. In this video, I present a long forgotten attribute on the thermoplastic properties of Casein, which seem to be overlooked by everyone. I will adjust the title here, but, I present the sustainable alternative to Formaldehyde in another video, for making Galalith. And, I don't know of any video on YT that presents Galalith, other than the one I have.
That sounds awesome, I'll check it out. Thanks!

yep. milliliter (mL). You're the first to call it out. When making an all or nothing segment, one is stuck with ones faux pas. I did say it correctly the first time, however.
