I cannot get enough of these videos. Thank you very much for sharing the info

You can also use acorns for your tannic acid. Quite abundant around here, especially this time of year.

Just discovered your channel, this is so interesting. Thanks.

Thank you sooooo much for your wonderful videis. I have learned so much from you. Love it!

Hi Robert, I am using nearly the same formula in a video on home compostable bioplastic. I would like to give you a shout out for leading me to the book on Casein uses.

Thanks!

So many great interesting videos. Thanks again.

Great video! After so many attempts I finally got the results and it survived for atleast 2 wash. I'm trying to find an alternative for tannic acid though and working on its flammablity.

I'd love to know what the tannic acid does exactly, is it forming crosslinks like formaldehyde would or is something else at work? I know barely anything about chemistry but your videos are motivating me to change that :).

Ah.. that´s better.. Thats even waterproof.. Nice!

Awesomee! I was going to ask if you knew any way to make an eco leather cloth or something similar! Gonna give it a try. Thank you for your videos. Love your channel!

Great video! Would the tannic acid waterproof a piece of cloth covered with gelatine as well?

wow very nice!! thanks!

When you say "all this stuff is food grade", does that include the borax? I only ask because I'm a potter and am experimenting with using milk to seal earthenware pots. It seems to work quite well so far (pour hot milk into a mug and leave it for a couple of days), but casein could be a good idea.

I think the million dollar question after this is... Is the cup of tea safe to drink afterwards? :-D Thanks for another brilliant upload. How safe is this rubber for say...tiny human beings who still think their nose can be detached and re-attached to their face? I know you said all the ingredients are food grade or relatively quite harmless, but would the combination of all those ingredients make the final product less safe than the individual stuff you put in?

what's the best dying phase?

This is interesting. I wonder how well it holds up to UV light?

Hi Robert 🤓We got some commercial tents made in China and the inside of the canvas most likely has this as the coating . They developed mould spots after a few uses from moisture. Probable didn't use the tanic acid or maybe their is an antimould like green banana flour that can be added . Any suggestion for something to prevent mould Robert ?

I was wondering if casein and whey were the same thing? Or if casein can be substituted with whey. I live in Australia and sometimes things are labelled differently.

hi mate_thanks for sharing your knowledge. just a question, i tried it out yesterday. i m not using a cloth 'cause i would like to get a thin layer of plastic just using casein, borax, water, glicerine and tannic acid. but, the result is drying now and it s full of cracks and it doesn t hold together. i follow your instructions, what could be wrong with it? thanks

Apparently micellar casein is not exactly the same is calcium caseinate as it doesn't seem to dissolve in water alone. When I do this experiment I end up with a milky white substance that does eventually dry and get hard but doesn't that go clear. I'm going to substitute some of the water with paper certain percentage of ammonia solution and try and find the right spot to be at. It stays then too it doesn't get gloopy at all it stays perfectly thin so I don't know what's going on in there because it looks like it has a dissolved it all yet it does act like in its forms of film and sets up It claims to be pure casein and clean. I made an alkaline solution and then threw down the case and with a little acid and the water was clear clean. So I don't really know what the difference is other than it will not go clear at all without being in an alkaline solution a little stronger than you get from this recipe

hi interesting video can this b applied to waterproof paper? is it safe for foods? thx

Should our farm industry looking to take their product to the chemical industry to improve on their farm gate price,rather than the super market/dairy conglomerates.Should we be looking more closely and considering this as a green plastics alternative,considering the embedded methane.Borax,good for the hands?

Can you avoid the tea colour with the tanic acid?

Would the rubber itself need a preservative?

how much tannic acid

how much glycerin did you use?
