Making eyeglasses from scratch with metal strainers, belt sanders, chainsaws, bandsaws, laser pointer, tracing old frames to cut new ones, a glass makers kiln, and the list goes on. What this video reveals is how blessed we are to have these technologies and how extraordinarily difficult it would be to rebuild without the assistance of previous knowledge and other technologies. 🤟
And one day we are going to lose it all. Maybe in thousands of years, maybe hundreds, maybe tens. Things are pretty crazy right now and it's never dumb to be prepared. Mentally prepared.
Your potash should be pure white. Instead of boiling to dryness, you need to perform a crystallization (there are books on the subject). The resulting crystals should be pure white (or transparent). You also need to purify the sand and the limestone. The sand can be treated with acid to dissolve out the iron (green) and other metals. The limestone should be fired separately, giving lime (calcium oxide) which should be pure white. Dissolve this in water, filter, and crystallize as for the potash. Weigh and Grind the powders together, then fire slowly to a full fluid. If you heat too long, crystals will form (de-vitrification, you want tot avoid this!) To grind the curve, you should rub 2 lenses together with abrasive slurry/mix between. By adjusting the length of the stroke, you can adjust the curve either steeper or shallower. You can measure the refraction by wetting the lens with soapy water. This is the way telescope mirrors are made. (There are many books on the subject).
I've been making glasses for over 15 years. You did really well. Plastics are what we use these days. It may be harder to make yourself but it's easier to work with. Plastics tend to be a little safer too, generally glass needs hardening to be considered safe. Even after that process it's still quite brittle if it's been compromised with a scratch or pit. There are also easier ways to make sure your prescription gets ground properly and uniformly. You'll also need to make sure your glass cools evenly when you make it or it will have aberrations in it.
I've been making eyeglasses for over 40 years so I had to laugh when I saw this. I think you must have left some steps out when grinding your lenses. Did you make laps to grind them with? Otherwise it would be very difficult to get spherical curvatures without massive waves in your surfaces. A lap is a tool that has the curvature needed to get your prescription ground onto the glass. The lap is abraded against the lens using a grinding compound until the lens curve matches the curve of the lap and then polished. Also what about astigmatism? This on the lens is called cylinder curve and axis. So I assume you just made spherical curves which may be good enough in dire situations to let you see. How would you know what your prescription is if you couldn't get an eye exam? Well if you know your Rx perhaps it would be useful to understand how they are used to determine the curvatures used to grind your lenses to. I see you used focal length. In the industry we do not use focal length. Your Rx is measured in diopters. Most are rounded to the nearest 1/8th Diopter. For example 1.33 would be either 1.25 or 1.375 Diopters. Also that would be ether a + power or a - power. Yours seemed to be a - or minus power. First you would decide what front curve you want. The way this works is the stronger minus Rx you have the lower or flatter the front curve should be. This affects the rear curve needed to achieve your Rx in the lens. If the front is too high a curve you have to grind a higher rear curve on the lens. It becomes more difficult as a curve gets higher to grind them. So for around a - 1.25 Diopter curvature you could use around a + 4.25 Diopter front curve. For a minus prescription you should be aiming for a finished center thickness of 2.0 or 2.2mm. This will be the thinnest point of the lens. So for a -1.25 Rx to calculate what the rear curve should be, you would take the front curve you are using (in this case +4.00) add the Rx power to it. +4.00 + 1.25 = -5.25Diopter rear curve. That is for minus Rx's, for plus you would subtract the power from the front curve. So for +1.25 Diopters it would be +4.00 - 1.25 = -2.75Diopter. Those are thinner at the edges. You are still putting a concave surface on the rear or back side of the lens. I will now explain what the curvatures are. In this example we determined we need a -5.25Diopter curve on the rear, so to understand what that is we need to convert the -5.25Diopter curve to it's radius of curvature. This done by taking the reciprocal of the Diopter curve 1/x multiplied by 530. So 1/5.25 x 530 = 100.952380952mm radius. To convert a radius back to Diopters, use the same formula only using the radius for x. The 530 here is the radius of a 1.00Diopter curve. You could now use the radius to make a gauge to measure against your lens curve as you work it in. Just draw an arc with that radius on either thin card board or plastic or brass. Then cut it out. You could use the same to create the lap. Spinning the lap against the lens while applying abrasive material. You will be using a concave lap on the front and a convex lap on the rear. There is actually a lot more to making glasses then covered here so this is just the basics. There is the index of refraction of your lens material. Do you know the index of the glass you are using? Standard glass is 1.523 which is close to what gives you simple calculations for the curvatures. 1.53 index gives you what is called True curves so 1.523 is close enough for addition and subtraction. Most glasses these days are made from plastics which are a lot easier to grind and polish. Hope this helps someone.
I really don't get why he didn't go and ask one of you guys as to how you create glasses. Why reinvent the wheel? Just ask someone who knows. Thanks for all this info. Very informative.
I would go a different route - instead of making glass I would pick fresh transparent resin out of pine trees, then melt and cast it into the basic lens dimensions.

Mistaken hypothesis and failed experiments teaches a lot about the the science behind a given process. As a scientist, I can tell you that I truly appreciate experimental failures. Seeing a protocol applied perfectly does not teach you about all the shortcoming you'll face when doing it yourself. In that regard, this video teaches a lot more than just glass making theory.
i know how the scientific method works, it's just people down here are all going on about how amazing this is even though he failed and didn't attempt to revise his methodology and try again. i'm just trying to address the balance with some scepticism.
13:20 your glass is full of copper oxide, that is what the green is. probably an impurity in either the soda ash or the silica sand, my bet is on the silica. although the limestone also often has marble in it which is also full of copper so you are being hit by copper from every direction. if you wanna get rid of it toss a led ingot in with it in the kiln and get it sloppy wet (hot) before you pour it. pour it slowly and leave the crap at the bottom out. the led will increase the heavy metal content to a point where you can get a separation from the silica glass mixture. the green oxide issue came from pouring everything out.
Looking at Jupiter’s planets with a homemade telescope would be quite astonishing. Not many understand that pivotal moment when galeleo seen the moons and planets that we were not alone. Definitely hoping to see you accomplish that difficult task. Cheers.
We were actually talking to the optometrist yesterday about this. You'd first have to make them out of plastic, but besides that he seemed to think they might be easier to shape then actual glasses.
How hard is it to make plastic? It wasn't around 100 years ago but now we know it can be made and have a method of making it maybe it can be done. I see a few 'how to make plastic' articles in Google. How about using sap, amber, intestines ..
Yeah, compared to a lot of projects we've done, this one was surprising easy to source the ingredients. Everything was locally available and there was basically no travel. Although if I had access to glasswort or seaweed like Lewis did, it'd probably be a lot easier.
3:00 A former co-worker of mine had the same thing happen but with a much worse result. He used gasoline to burn some dry brush on his property and let it sit for too long so it evaporated a bit, but the vapor stayed low to the ground. When he ignited it, he was engulfed in flames, and he was severely burnt. He is ok now, but he required skin grafts on his arms, hands, legs, and face (I think). He showed me pictures from the hospital, and I can't believe he is alive and able to work still, especially since he's in his 60s.
As an Optometrist who has spent 30 years in private practice, I can tell you that considering the time and trouble you would need to go through to make your glasses, it's a lot cheaper to buy them. There are some things that most people don't understand or are not unaware of that go into making spectacle lenses. A big one is astigmatism. Some people are just farsighted and some people are just nearsighted but most people are astigmatic. That is, they have either a nearsighted type of astigmatism, a farsighted type of astigmatism, or just astigmatism. Grinding toric lenses, the kind of lens that correct astigmatism, is much more difficult than making the kind of lens you did, a sphere. There is one more thing you neglected to consider and that is your interpupillary distance. Assuming you don’t suffer from strabismus, exophoria, esophoria or hyperphoria, you need to set the optical centers of your lenses' the same distance apart as your pupils. If you have one of these vision problems than prism may need to be ground into your lenses. All in all, making glasses isn’t as easy as it looks. .
Waldglas (potash glass) melts at a much higher temperature than soda glass. So it is much much harder to get clear because it is as you saw much much more viscous at temperatures where soda glass will flow quite freely. I also has a lot higher amount of iron contamination in it. Which gives the green colour. The German cathedrals had waldglas windows as at the time they couldn't make or trade for soda and they went to quite extraordinary lengths. Like separating wood by the tree type and even growing conditions. For instance wood ash trees growing in a swamp usually has more manganese in it than other trees. This produced glass with a bluish cast that could be later melted with glass with a more greenish or yellow cast to produce glass with a more neutral cast, making it appear clearer. They still do something like this today in soda glass by adding a little extra manganese dioxide to clear bottle or even window glass, so they can use a cheaper and not so pure white silica sand. Which is why glass when you look through a great thickness usually has a blue cast. You could fake this by adding tiny amount of washed manganese dioxide from a dead AA battery. The carbon also present should burn up. Also if you are going to do it again using potash, probably only collect only the fluffy white ashes. I know it's a huge pain, but it isn't an exaggeration at all to say the German cathedral builders consumed entire forests to produce the stained glass windows.
There are plenty of videos on it already, but there is a thing called a "Foldscope" by Manu Prakesh at Stanford. It's a foldable paper microscope with one single lens. Mark Rober just made a video about it called "How to save 51 billion lives for 68 cents with simple Engineering."
Amanda Graff was thinking the same. He could put it on the back surface with a different type of cylindrical grinder maybe but then guess work with a tape measure is pretty useless. Should of taken them in to his optometrist. He would of thought they were cool and checked how close he got
When the dog ran away that was funny but OMG andy i know you worked so hard and i hate to laugh but when you put on YOUR glasses with the homemade glass i was on the floor when you revealed them man i dont know how you kept a straight face when talking about them
I'm thinking it's because of his potash either being a low quantity or not so pure. Without a proper mixture, the melting point of the silica (which isn't pure either) remains relatively high (pure silica's melting point is 1723°C).
Wow. Whatever changes to production You guys made, the finished product looks polished and dope. The graphics and music are on point. Couple of months ago I written mean-ish comment about moderator, and I take it back. And I am sorry :) In the beginning - the skype call - could use a bit less jumping, just leave the moderator in the small window, it took away from the actual conversation. And to whoever edited this video: I wish I could buy You a beer.
Thanks! I actually did the final edit myself. The call with Dartnell wasn't filmed until the day before we released and I had to spend the next 30 hours straight finishing the editing to have it ready to release in time. This is our first series we've shot entirely with the new format we've been trying to do (coffee was mostly already shot before we decided to change it), so it's definitely satisfying to see it being well received. I think we've learned a lot the past year about what does and doesn't work and this new format should hopefully fit the youtube format better and also play better to my strengths as the host (less trying to be a TV host, more just documenting my own journey)
Man I’ve been watching this on and off for a long time, and I’m always impressed by your videos. I’ve got a wide variety of skills…( none of them I’m that great at). However if you’re ever near north Georgia, I’d be glad to help you with any of your projects however I can. I’ve got everything from lamp work and glass work equipment, metal machining equipment like lathes and mills, a massive amount of woodworking equipment that I can’t seem to stop acquiring, also a lot of jewelry equipment such as casting gear and such… i’ve been lucky to acquire a lot of the stuff at a very low price over the last 15 years, and restored most of it myself. Otherwise it wouldn’t have been affordable… So if you’re ever in need of any help near my neck of the woods feel free to reach out!

Prescription glasses are insanely expensive. Although in America (and probs other places) that’s not just the production costs... And manufacturing is quite optimised tbh
Because he trying to make it from scratch , with right tool those company can make your glasses in less than 10 usd , my prescription lens + double beam frame cost only 75 cents from factory , 300 USD is a insanely mark up price.
just as a word, I live near the quarry where the silica sand was was harvested for the glass that made the mirrors for the Hubble telescope. does walking in their front door and buying a couple pounds of sand count as doing it from scratch? by the way, great idea to team up with Picciuto. I'd never have found your channel otherwise.
The fire explosion when lighting the pit with an accelerant was likely from the debris in the pit trapping vapors and them igniting violently. Can be very dangerous. Actually had a pile of leaves and gas go off like an m80 because of this.
The guy he is Skyping with, Dr. Lewis Dartnell, should start a TV show where he gives guidance to three teams which are competing to build a village from scratch. In each episode they race to produce something new as fast as possible and of the highest quality possible.
Dude, this is great. Your videos are a must watch for proving the comparative advantages of commerce. I mean, free market with it's own price system and division of labour is the best way to get better societies. Greetings from Mexico :)
Why do people say sorry when their dog comes over to say hi what do you mean you're sorry this is the best thing that has happened to me all day hello doggo
The trick to purifying your potash is called re-crystallization. It only requires water, heat, a filter, and patience. You boil the water and add in as much of your crude potash as will dissolve. Then pass the hot solution through a paper filter and let it cool. As it cools, it will (should) grow crystals of relatively pure potassium carbonate. Unfortunately I don't know a good way to get cleaner sand. If you find out I'd love to know.
Lewis: try to make a telescope. Me: he couldn't even make the glass for the glasses. How is he going to pass that challenge if he can't even get the first part right.
Awesome, although I don't feel like the intro should imply post apocalyptic applications or whatever, if using electric kilns, power grinders, chainsaws, etc. Not that it's worth anybody's time to do all this with hand tools, rather the context being a bit at issue. Anyway, I've done some homemade glass before, and did repurify the potash and it did not help with the bubbles, still had your same issue. One possible alternative might be an even hotter furnace and attempting quartz-only "glass"?
I really like to laugh first thing in the morning. You did it for me today! That glass in your first pair, Fred Flintstone's 2022. I'm old. When the dog jumped up due to the explosion LOL!

How hard is it to make plastic? It wasn't around 100 years ago but now we know it can be made and have a method of making it maybe it can be done. I see a few 'how to make plastic' articles in Google. How about using sap, amber, intestines ..
Interesting, formaldehyde looks possible to make from scratch. That might be doable. I'll definitely be looking more into this.
Wow!the processes of inventing is so complex.
This channel is making so much effort in its videos and its sad it doesnt get much support because it deserves it ;)
Sooo this channel deserved to have not that much support?
Nathanael Raynard read it again.
Yeah! Only 447k subscribers? What?!
Pupper on the beach! The entire endeavor was worth it!
HTME and Primitive Technology need to collaborate
+International Cartoons
Yes, that is an Esperanto flag. :)
Athenic Cuber jes!
Saluton!
Woohoo! Esperantistojn amikojn!~
titled "Civilization"
This channel keeps on getting better and better! Keep supporting them so they'll keep growing!
While this was a spectacular fail (bit of a pun ;) ), I loved this video. What a worthy project... mainly as the raw materials are just SO available.
Yeah, compared to a lot of projects we've done, this one was surprising easy to source the ingredients. Everything was locally available and there was basically no travel. Although if I had access to glasswort or seaweed like Lewis did, it'd probably be a lot easier.
Chad LaFarge could've possibly used nori from sushi as a seaweed source. Also worth noting that many early lenses were ground from rock crystal.
3:00 A former co-worker of mine had the same thing happen but with a much worse result. He used gasoline to burn some dry brush on his property and let it sit for too long so it evaporated a bit, but the vapor stayed low to the ground. When he ignited it, he was engulfed in flames, and he was severely burnt. He is ok now, but he required skin grafts on his arms, hands, legs, and face (I think). He showed me pictures from the hospital, and I can't believe he is alive and able to work still, especially since he's in his 60s.
The microwaving your wood dry idea is the best idea I've ever heard!
As an Optometrist who has spent 30 years in private practice, I can tell you that considering the time and trouble you would need to go through to make your glasses, it's a lot cheaper to buy them. There are some things that most people don't understand or are not unaware of that go into making spectacle lenses. A big one is astigmatism. Some people are just farsighted and some people are just nearsighted but most people are astigmatic. That is, they have either a nearsighted type of astigmatism, a farsighted type of astigmatism, or just astigmatism. Grinding toric lenses, the kind of lens that correct astigmatism, is much more difficult than making the kind of lens you did, a sphere. There is one more thing you neglected to consider and that is your interpupillary distance. Assuming you don’t suffer from strabismus, exophoria, esophoria or hyperphoria, you need to set the optical centers of your lenses' the same distance apart as your pupils. If you have one of these vision problems than prism may need to be ground into your lenses.
All in all, making glasses isn’t as easy as it looks.
.
Well said.
Lol his dog took off and broke the gate when the fire started haha
Waldglas (potash glass) melts at a much higher temperature than soda glass. So it is much much harder to get clear because it is as you saw much much more viscous at temperatures where soda glass will flow quite freely. I also has a lot higher amount of iron contamination in it. Which gives the green colour.
The German cathedrals had waldglas windows as at the time they couldn't make or trade for soda and they went to quite extraordinary lengths.
Like separating wood by the tree type and even growing conditions. For instance wood ash trees growing in a swamp usually has more manganese in it than other trees.
This produced glass with a bluish cast that could be later melted with glass with a more greenish or yellow cast to produce glass with a more neutral cast, making it appear clearer.
They still do something like this today in soda glass by adding a little extra manganese dioxide to clear bottle or even window glass, so they can use a cheaper and not so pure white silica sand. Which is why glass when you look through a great thickness usually has a blue cast.
You could fake this by adding tiny amount of washed manganese dioxide from a dead AA battery. The carbon also present should burn up.
Also if you are going to do it again using potash, probably only collect only the fluffy white ashes. I know it's a huge pain, but it isn't an exaggeration at all to say the German cathedral builders consumed entire forests to produce the stained glass windows.
I really enjoyed this. Very impressive Job on grinding the lenses! I wish you all the best. Such a high production quality and value.
You are LITTERALLY living my dream ! Making things from scratch !
The dog at 3:03 though! Went through the fence!
At 3:03 the dog was like: "Bitch, you is crazy"😂😂😂😂
just a question, why do some Americans call glasses eyeglasses? where else would they go?
I only say glasses, but I suppose some people might want to distinguish eyeglasses from drinking glasses, since they are both just called glasses.
Great question, ByThe...HEY, WHERE'S MY BAGEL?!
on youre ass geez... how do you use glasses? on your face? HA thats the first time i heard that one
Hmmm.... I haven't heard that in a while.
I'd say "glasses" is usually more common, but I wanted to make sure I used as clear of terminology as possible, since it can be ambiguous.
YES MAKE THE TELESCOPE!!! I subscribed for this.
To create anything from scratch, you must first create the universe.
Maxx Kroes boom you've made everything to ever exist from scratch good job
Sebass God created all things and the one who created all things came down to save you from your sins you commited
David Aragon
Ugh. I'm a Christian but honesty, the Internet is not the best medium to preach. In fact it's quite annoying.
Sagan, woo hoo.
Sebass True...
When he lights the fire for the hardwood ash, look at the dog in the background. Its reaction is priceless.
I love your determination. Never give up. I'll be waiting for next big thing built from scratch
Just discovered this channel and the content is AMAZING!!! Totally smashed the subscribe button!!!! Looking forward to your future work!!!!
I would love to see a telescope or a microscope!
There are plenty of videos on it already, but there is a thing called a "Foldscope" by Manu Prakesh at Stanford. It's a foldable paper microscope with one single lens. Mark Rober just made a video about it called "How to save 51 billion lives for 68 cents with simple Engineering."
Both, please!
CodeIsGrit he made a telescope version!
He made a microscope
Why not finish making the glasses so he can see through them?
Yeah I'll just stay over here with my acrylic shatterproof lenses. It is REALLY cool that you did this. Now making frames? I'm up for that!
Very good video, the other channels referenced here are on my 'next to' list, lots of great and well appreciated content, and entertaining to boot!
thinking how much more difficult this would have been if you had any astigmatism. such an interesting video!
Amanda Graff was thinking the same. He could put it on the back surface with a different type of cylindrical grinder maybe but then guess work with a tape measure is pretty useless. Should of taken them in to his optometrist. He would of thought they were cool and checked how close he got
Some people don’t vaccinate their kids because of that
@@vinish542 underrated joke, that was hilarious
terriblegoatman thank you thank you, I tried my best!
When the dog ran away that was funny but OMG andy i know you worked so hard and i hate to laugh but when you put on YOUR glasses with the homemade glass i was on the floor when you revealed them man i dont know how you kept a straight face when talking about them
Wait what? You heated the glass for several days?
Yeah that one made me "WaitWHAT?!" in real life :P
Olari Tsernobrovkin probably to avoid the seeding that ultimately ruined his glasses
I'm thinking it's because of his potash either being a low quantity or not so pure. Without a proper mixture, the melting point of the silica (which isn't pure either) remains relatively high (pure silica's melting point is 1723°C).
I like how the dog just goes 'nope nope why is this gate here GET OUT OF MY WAYYY'
Wow.
Whatever changes to production You guys made, the finished product looks polished and dope. The graphics and music are on point.
Couple of months ago I written mean-ish comment about moderator, and I take it back. And I am sorry :)
In the beginning - the skype call - could use a bit less jumping, just leave the moderator in the small window, it took away from the actual conversation.
And to whoever edited this video: I wish I could buy You a beer.
Thanks! I actually did the final edit myself. The call with Dartnell wasn't filmed until the day before we released and I had to spend the next 30 hours straight finishing the editing to have it ready to release in time.
This is our first series we've shot entirely with the new format we've been trying to do (coffee was mostly already shot before we decided to change it), so it's definitely satisfying to see it being well received. I think we've learned a lot the past year about what does and doesn't work and this new format should hopefully fit the youtube format better and also play better to my strengths as the host (less trying to be a TV host, more just documenting my own journey)
Man I’ve been watching this on and off for a long time, and I’m always impressed by your videos. I’ve got a wide variety of skills…( none of them I’m that great at). However if you’re ever near north Georgia, I’d be glad to help you with any of your projects however I can. I’ve got everything from lamp work and glass work equipment, metal machining equipment like lathes and mills, a massive amount of woodworking equipment that I can’t seem to stop acquiring, also a lot of jewelry equipment such as casting gear and such… i’ve been lucky to acquire a lot of the stuff at a very low price over the last 15 years, and restored most of it myself. Otherwise it wouldn’t have been affordable… So if you’re ever in need of any help near my neck of the woods feel free to reach out!
Everyone complaining about him chopping down ONE tree, but when millions are chopped down every day, no-one seems to care.
SwiftAtaraxy exactly. not to mention the tree was dead and needed to be cut anyway!
Wetgasm "The tree was already dead and needed to be cut. The leftover wood will be reused in other projects, because wood can be used for more then one thing." - How To Make Everything himself
QUIT THIS CHANNEL yea it's like trees won't grow back or anything
Wetgasm It's not like he just threw the rest of the tree in the trash when he's done lmao
Yeah same thing with turkeys on thanksgiving
This channel is awesome. It will take time but this channel will get what it deserves.
That's basically Dr. Stone in real life. One word AWESOME
1 billion percent awesome
The glasses with the clearer glass look really good on you, and what a great story to be able to tell about a pair of glasses
3:06 I bet the dog was like "I better get my ass outta here"
The work you put into you videos is inspiring. I need to step up my game.
That was so much work, I no longer feel bad for paying $300 for my prescription glasses 😳
Prescription glasses are insanely expensive. Although in America (and probs other places) that’s not just the production costs... And manufacturing is quite optimised tbh
Because he trying to make it from scratch , with right tool those company can make your glasses in less than 10 usd , my prescription lens + double beam frame cost only 75 cents from factory , 300 USD is a insanely mark up price.
This dude deserves his own tv show. This is amazing and very educational.
just as a word, I live near the quarry where the silica sand was was harvested for the glass that made the mirrors for the Hubble telescope.
does walking in their front door and buying a couple pounds of sand count as doing it from scratch?
by the way, great idea to team up with Picciuto. I'd never have found your channel otherwise.
Everyone like this video hats off to you man lots of hard work goes to making a video such like this
The fire explosion when lighting the pit with an accelerant was likely from the debris in the pit trapping vapors and them igniting violently. Can be very dangerous.
Actually had a pile of leaves and gas go off like an m80 because of this.
The guy he is Skyping with, Dr. Lewis Dartnell, should start a TV show where he gives guidance to three teams which are competing to build a village from scratch. In each episode they race to produce something new as fast as possible and of the highest quality possible.
it's fun how the camera keeps getting out of focus once he tries the new eyeglasses
That fire ball was crazy awesome!!!!!
I like how this guy cuts down an entire tree just to make a frame
You do know he keeps everything to use in others projects, right?
Whoa that’s some fire 🔥
3:03 lol the dog was out of there 😂
Those ones that the wood expert guy made were actually pretty cool. Bet u gucci will use something like that in the shows next year
Dude, this is great. Your videos are a must watch for proving the comparative advantages of commerce. I mean, free market with it's own price system and division of labour is the best way to get better societies. Greetings from Mexico :)
Why do people say sorry when their dog comes over to say hi
what do you mean you're sorry
this is the best thing that has happened to me all day
hello doggo
3:01 the dog is like "iam outta here"
This is brilliant! I just need to make new frames for my lens....and came across this... fascinating!
5:46
*casually drops molten glass on floor*
Catches fire and burns too
Very interesting - I enjoyed watching. Well done.
2:05 the dogs like "I'm outta here" 🖕🏿🙂
Harry 🤣🤣
Dude! You deserve so many more subscribers. This was actually really interesting 😁
I attended a TED talk event where Lewis Dartnell was speaking. it blew my mind away.
The trick to purifying your potash is called re-crystallization. It only requires water, heat, a filter, and patience. You boil the water and add in as much of your crude potash as will dissolve. Then pass the hot solution through a paper filter and let it cool. As it cools, it will (should) grow crystals of relatively pure potassium carbonate.
Unfortunately I don't know a good way to get cleaner sand. If you find out I'd love to know.
His channel should be on tv
I was just thinking about that! :)
This channel is a gem. Hell yeah
doggo is like fuck this shit iam out of here
3:05 the dog didnt care about anything else and just left like he did not want to die
This channel is insane, deservs so much more subs
This channel is underrated
HE MICROWAVED THE WOOD.
Yeah dude, have you never tried it before? Tastes great! I like siding it with a bit of stewed mold.
Oscar Gonzalez Mold is alright, but smoked mildew is far better.
Bro I read it right as the microwave beeped and he pulled it out
The dog made my day🐕🐕🐕🐶🐶🐶🐾🐾🐾
Side note: The pitbull not when his dog got scared
Lewis: try to make a telescope.
Me: he couldn't even make the glass for the glasses. How is he going to pass that challenge if he can't even get the first part right.
Yeah im TOTALLY gonna make it
Awesome, although I don't feel like the intro should imply post apocalyptic applications or whatever, if using electric kilns, power grinders, chainsaws, etc. Not that it's worth anybody's time to do all this with hand tools, rather the context being a bit at issue. Anyway, I've done some homemade glass before, and did repurify the potash and it did not help with the bubbles, still had your same issue. One possible alternative might be an even hotter furnace and attempting quartz-only "glass"?
Gavin Jenkins, or make real Coke bottle glasses.
I really like to laugh first thing in the morning. You did it for me today! That glass in your first pair, Fred Flintstone's 2022. I'm old. When the dog jumped up due to the explosion LOL!
Shouldn’t the How To Rebuild The World book be written in pictures which would teach how to read and write because if the world did end, after years after the end no one would know how to read and write.
Was that an Emmy award in the background when he was unboxing the frames?
