    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..

    @@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!

    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.

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

    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 😄

    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...

    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, you have to use warm water. The more hot, the more elastic is will become. Keep working it in the water.

    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.
