Amazing video... was looking for a plant based molding material since i turned vegetarian and this works perfectly... this comparison was extremely helpful
Is this correct? 500 ml of water 1% glycerine - 5ml 1 part agar - 10 ml (500:50=10) I thought that the agar shouldn't be more than the glycerine. But doing some calculations that's what it looks like. I then checked you video quantities and it looks instead that the glycerine and the agar have same measurements (2 tsp for 1L water) Can you please help? 500 ml of water 1% glycerine - 5ml 1 part agar - 10 ml (500:50=10) i
That is correct for a 50:1 ratio of 1% glycerin solution agar bioplastic, yes. I think the confusion came from the fact that I posted the quantities for 1L of solution. Then, out of that, I only prepared and poured 160mL of bioplastic into the mould, so I get the desired thickness.
Hi i did something similar like this, did it with agar and gelatine, both of them dried with molds on the surface what did i do wronnggg??,😭😭 its for a science project pls answerrr
Hmm... I've never had that happen to me, usually takes a while until mold develops. If you're doing it in a place that might have lots of natural contaminants, like a kitchen counter, maybe try and disinfect the surfaces and utensils before you start the preparation?
When you see a recipe expressed in 'parts' that means you are looking at the recipe 'ratio', which is supposed to help you scale the quantity up and down. Example: let's say you don't have measuring spoons at home and all you have is a small coffee cup. If the ratio called for 3:1:1, that would be 3 cups of water, 1 cup of glycerin, 1 cup of gelatin. Then, let's say you wanted a bioplastic that was double the size. You can use a coffee cup that is double the size, or, following the same ratio 3:1:1 all you need to do is double the numbers, so that would be: 6 cups of water, 2 cups of glycerin, 2 cups of gelatin.
I really like the idea. Is it possible to make it transparent? Do you think it would be possible to create a protective cover for the table with agar plastic?
Is there a formula to calculate the right measurement for a specific quantity of plastic? Like you did 160 ml solution = 30X20 cm .. if I did 100 ml? Or 250? Or so on?
hi so our group needs to make this for a final term project and i would really appreciate a reply - much so if early! english isn't my first language and im no good at measuring ratios much, so when we tried making this with the agar recipe it gave us this rough texture that was also extremely easy to rip apart. so questions are (sorry for being a hassle lol): - if we're trying to make this with 300g of water what would be the measurements for others? - and do you have any idea what would be the cause of that texture i described earlier? im sorry for asking so much, ik u said the measurements are at the end of the video but me and my group can't seem to figure it out at all. thank you again!
Hey, I hope you see this comment and reply to me asap. I used exactly the same quantities, also the 30x20 shape. But unfortunately it's day 2 and it's like pudding instead of a thin layer like yours. What could be the reason for this?
If you don't have access to a dehydrator, the only thing I can think of to speed up the process is to pour it as thin as possible. You can try putting it in the oven at the lowest temperature possible (70ºC max.), but it might introduce a lot of bubbles. Also, the less glycerin you add, the faster it'll dry, but the more rigid and irregular the bioplastic will be.
hi we also made bioplastic made from agar agar powder but with a twist we add soak naoh fish scale to it we use agar agar as the ingredients to make plastic work we also use the measurements as you did and we let it dry for 3 days but the texture is like gelatine it doesn't look like the texture i see in the fina results as you did what do you think we did wrong in this??
By "cup" I don't mean my own cup, but the common cooking measure of volume in the US; you can easily convert to mL by searching on google "cup to ml conversion".
@@giestas oh, ok. I measured by teaspoons, in the glycerin with water I put 192 teaspoons of water and two of glycerin, then I put 48 teaspoons in the pan and put it on the fire.

@@giestas yess. The materials we used are Agar agar powder, glycerin, water, and vegetable oil to make mask smooth. We're actually having a problem on it's filter efficiency, because the filter also needs to be biodegradable. Also a problem on how to make it durable 😭

Changing the amount of glycerin has a big impact in the outcome (more flexible, more fragile), changing the amount of gelatin / agar doesn't produce much change.
thank you. 🤗 Lat question hehe. Do you put a cover on it while drying? or you just leave it alone? i am afraid that some particles can be absorbed in the mixture while doing the latter
I guess that wouldn't make the water evaporate more quickly. If you have an oven that does low temperatures (something like (50 to 70ºC) and has a fan option, it'll work like a dehydrator.
I'm guessing a moderate amount of powder pigment won't affect the mixture that much. If you want to make it opaque I'm not sure what that powder pigment should be; maybe something like charcoal?
@@giestas is there any other way to dry it faster? I need it dry in 4 hours, and they have already passed 20 hours, it's like gelatin, and doesn't gets more dry
I live in a place where humidity is high. This also happens after I touched it with damp hands, I tried drying the BioPlastic sheet with paper towels later, but it continues “sweating”. I store it in a container, but I do open up to check on it and touch it.
Hmm... peculiar. I've had that happen in the peak of winter to some potato and corn starch bioplastics, but never to the agar, so I though the agar was immune to that.
Not really. Whether you're making agar or gelatin, it should still be fluid after being in the stove. The idea is to cook it just enough to dissolve the solids.
You probably won't find at a regular supermarket. In a big online retailer you'll easily find "food grade glycerin" or "food grade glycerol". You might also find it locally at some pharmacies/ drugstores and supplement stores (or even specialty cooking shops, like those that sell all kind of ingredients for elaborate cakes).
The agar one won't change much with or without refrigerator. The gelatin will congeal faster if you put it in the refrigerator. Refrigerators have dry air inside, but not so much that it'll work as a dehydrator.
@@KarlaGonzalez-gj9dn You can try the oven at lower temperatures like 70ºC (158ºF), ideally with fan on, for a few hours. More than that and the oven will introduce a lot of bubbles in the bioplastic.
Does it change a lot if you would just add the glycerin directly to the heating water (like your previous gelatin video) instead of doing the 1% solution beforehand?
Hello, may I as if what's a faster drying method, should I expose it in the sun or use a blow dryer or what because I'm on a rush and we don't have a dehydrator, need help pls
Hello!I was trying to make the gelatin bioplastic, I tried putting the mixture on different surfaces, however I'm having trouble peeling it off, it usually rips in some places while getting it off because some of it gets stuck on the surface. I tried using baking trays, and even non-stick pans and pots, but I'm facing same issue. The plastic is forming and some of it is getting off, but most of it is ripping and sticking to the surface. Please advise what would be going wrong and what I could do to fix it. Thank You.
Difficult to say without looking at the samples, but if it sticks even to non-stick surfaces, maybe you're not letting it dry completely before peeling?
@@giestas Thanks for replying. Hmm, I left mine to completely dry for 3 days and then even for another day to make sure, so I don't think that's the problem :(
@@emmanuelmatewere7575 i did. i tired many times putting different amount of glycerin and using different surfaces, but none worked. It just rips as i try to peel it so i am not able to get a full piece.
@@haleemayaseen that’s unfortunate, as for me, I tried adding more glycerin and it easily peeled off. Maybe just make sure you are using the right quantities
I'm curious about using a bioplastic recipe like your agar one to make miniature charms and toys that I would otherwise make with resin. Have you had any success drying thicker sheets of these recipes? I'm not sure if it would just take longer to dry or just not dry at all 😅
Haven't tested that properly, but I'd guess it'd shrink so much while drying that it wouldn't be usable; if you add a filler material, then it might work, but I'll have to explore that more in the future.
@@minkin_5751 Actually I don't know, I've never tried. (I did that for the starch based bioplastics and it doesn't really work, it introduces a lot of bubbles).
@@giestas what happens if you dry it at the sun? I did a similar experiment about this but i am having a hard time drying the bioplastic, does the thickness of the formula matter?
The purpose of glycerin is to act as a plasticizer, to make the bioplastic flexible. If you don't have access to glycerin, try replacing it with honey, I did that for the starch based bioplastics ( ruclips.net/video/lU1RiQTmLuA/видео.html ) and it turned out fine.
@@giestas Hello! I tried using glycerin oil and it worked! There were quiet a few bubbles, however the plastic was very flexible and strong. And it set faster as well. I even tried it using lemon juice, but it was a little brittle and not as flexible.
@@zhansbk I'm guessing the hairdryer won't be very efficient. Once you have the mixture cooked, try to pour it in as thin a layer as possible, like 2 mm deep; otherwise it'll take much longer to dry.
Hi do you think after pouring I would be able to add 'objects' possibly organic such as matter found in nature ? leaves , powdered rocks etc would this interfere with the setting process? thanks

80ml (1/3 cup)
@@giestas how should I adjust the amount of my agar agar?
Hi! I did the exact process but my solution is still watery after several hours and I used agar
That's totally normal! It takes about three days for the bioplastic to dry.
Can I use an oven as an alternative to a dehydrator to make the drying process faster?
@@minkin_5751 Actually I don't know, I've never tried. (I did that for the starch based bioplastics and it doesn't really work, it introduces a lot of bubbles).

Where did you placed it to let it dry? Is it under the sun?
These drying times are for room temperature, they dried inside the house.
hello do you need dehydrator for this to dry? Or you just leave it be?
You can do it without a dehydrator, for sure, even at room temperature it'll dry, it just takes longer.
@@giestas what happens if you dry it at the sun? I did a similar experiment about this but i am having a hard time drying the bioplastic, does the thickness of the formula matter?
@@janedoe4519 sun drying also works. Try to pour the mix on a wide mould, so you get a shallow pool of liquid. Otherwise it'll take forever to dry.
Hi! Can I use lemon juice instead of glycerin as the lemon juice contains citric acid?
Or "Pure Glycerin Oil"
The purpose of glycerin is to act as a plasticizer, to make the bioplastic flexible. If you don't have access to glycerin, try replacing it with honey, I did that for the starch based bioplastics ( ruclips.net/video/lU1RiQTmLuA/видео.html ) and it turned out fine.
@@giestas Okay will try that thank you, I Found "Pure Glycerin Oil' would That work?
@@haleemayaseen I've never used glycerin oil; try it and let us know if it works out :)
@@giestas Hello!
I tried using glycerin oil and it worked!
There were quiet a few bubbles, however the plastic was very flexible and strong. And it set faster as well.
I even tried it using lemon juice, but it was a little brittle and not as flexible.
Would you tell me the measure of agar in grams?
You can find the measures at 02:48 in the chapter "quantities & dimensions".
is this edible?
I would guess so, but since I can't be sure, I'd rather not say :)
hello
What is the size of your silicon mold?
It's 300 x 200 mm
@@giestas how can I make agar dry quicker?If I dry it with hair dryer,will it help?
@@zhansbk I'm guessing the hairdryer won't be very efficient. Once you have the mixture cooked, try to pour it in as thin a layer as possible, like 2 mm deep; otherwise it'll take much longer to dry.
Hi do you think after pouring I would be able to add 'objects' possibly organic such as matter found in nature ? leaves , powdered rocks etc would this interfere with the setting process? thanks
The setting process will probably still work fine, go for it!
Hi! What is the size of bioplastics or silicon molds?
Huhuhu… it did not worked for me.
What does 50 parts mean 😭
When you see a recipe expressed in 'parts' that means you are looking at the recipe 'ratio', which is supposed to help you scale the quantity up and down.
Example: let's say you don't have measuring spoons at home and all you have is a small coffee cup. If the ratio called for 3:1:1:1, that would be 3 cups of water, 1 cup of starch, 1 cup of vinegar, 1 cup of glycerin.
Then, let's say you wanted a bioplastic that was double the size. You can use a coffee cup that is double the size, or, following the same ratio 3:1:1:1 all you need to do is double the numbers, so that would be: 6 cups of water, 2 cups of starch, 2 cups of vinegar, 2 cup of glycerin.
@Giestas So in the video, when u said 50 parts of the water and glycerin solution, does it mean 50 teaspoons / 1 cup? Then u add the 1 part of agar, which i can assume is 1 teaspoon?
@@hanhanhaaann Yes! You got it! That's how it works. (48 teaspoons in a cup)
Why dont you start tour own company
Es una basure el vidoe porque no esplica bien las cantidades
