Super nice video, thanks for that! I've been experimenting with casein for a while. What do you think of adding Borax to the mixture?

You have several things I need to answer. Borax is not renewable, so I don't use it. Add Tannin or Silane after it has dried, like a paint. Strength is inherent, you have what you have. Shrinkage may best be controlled with Glycerine. It does slow drying time.

Like all chemical bonding, cross linking takes time, no less than 24 hours, even one week would not surprise me. This would be true for Tannin or Silane as well. Time adds to the water resistence.

Wow, I never knew anything about this! I've seen videos where people claim to fix a plate that was broken into pieces by just using milk but I never believed it because all they did was tape the plate together and they soaked it overnight. Magically the plate was restored as if it was never broken. I found that kinda suspicious lol. But THIS! This makes sense. I wondering if you could do a video showing how to mold this Galalith using say a silicon mold in order to make a stone and how to paint details into it to make it appear as marble or even jade. Can one add paint to the milk before adding the vinegar? Will the casein be colored by the acrylic paint or perhaps food dye? Thanks so much for the video.

How can I polish the galalith? I'm desperate ;-) I'm a pen and pencil collector. I bought a pair of splendid pencils from the UK on Ebay, made in England, I believe in the 1950s by a historic brand, Conway & Stewart, one red and one blue, both with marble-like veins. Unfortunately, this summer one took a while. of water. The surface has become dull with a few tiny scratches. I didn't know that this material was sensitive to water. Then I learned that this model was made for secretaries, because it was only intended for desks, as it was sensitive to water. At the time, for models to be used even outside the office, they used a water resistant material which was Durapoint, a plastic made by Dupont

Still, in my opinion, you have the better deal. Because of the value and rarity of these, I can only recommend you take it to a person that can restore them. A person that restores art would be my first thought. Yes, Galalith is sensitive to water if not finished in formaldehyde. Curious, are you sure they are not fakes? I know Galalith was used for uniform buttons and I am sure they got used and washed a lot. Unfortunately, we are discussing a lost art, one that plastic from DuPont killed. There are folks that still make guitar picks with Galalith, perhaps they would know how to polish it. In the end, restoring it will change the value. Such a shame to hear about your accident.

Thank you for the Tannin and Silane. Believe it or not, I was contemplating meat glue. I knew about the formaldehyde. But nothing about "green" alternatives for cross-links. I would have liked too see how you used the alcohol and water to make the casein rubbery. One suggestion was to use ammonia to get it to be rubbery, if memory serves me right. Hmm... Should I look up how mozzarella cheese is made rubbery? :D Thank you very much.

@GEOsustainable

6 жыл бұрын

Mozzarella cheese is made the same way. Citric Acid is used wherein I use viniger. Both are acids. The alcohol is used to remove any remaining milk fat and milk sugar that are not wanted. What makes the Casein rubbery is the hot water, but it is not permanent. A pure Casein will dry rock hard. Ammonia will dissolve the Casein, forming polymer chains. This is not what you want in the making of Galalith. What I demonstrated was how to coagulate Casein to make a lump. The next video will be on the making of another type of costume jewelry that imitates rubies and emeralds. In that video, I use ammonia to make plastic costume jewery. Watch for that one as that will present your thoughts.

@GEOsustainable

Yes, the alcohol is used to remove the trace fat and milk sugars from the milk. The main function of the alcohol (or ethanol) is to remove the fat and sugar from the curds. (A very important step is precipitating Casein from milk as you want the Casein as pure as possible). It also works great for displacing water by attaching to it. Tannin is found in tea and wine. I buy wine tannin, as it gives less color to the finish. Using tea will of course give your Casein a tea color. Silane is an inexpensive sealer that will not impart any gloss or sheen to the finish.. I read a research paper where it was used to waterproof Casein. As I mentioned in the video, my plan is to use Shellac, which is the secretion of the female Lac bug (as natural as it comes). As for your meat glue. I have heard of Casein used with gelatin, have you considered that?

@abdallahhigazy3203

6 жыл бұрын

GEO-sustainable What I understood from the gentleman who was describing using the formaldehyde is that you soak it in the stuff and there was a formula for thickness vs number of days. I was under the impression that shellac is a polymer liquid (for a lack of better description) that prevents water from seeping into wood. I had no idea that it was natural. Do you just paint it on? Is the casein plastic porous? Would you put it in a vacuum with the shellac? (Not that I have one :)). How were you going to use the shellac? And since you mentioned gelatin, how would it be used? Do you mix it in with the casein? Do you pain with it? What do you do? Thank you very much concerning explaining tannin and silane. :)

There is a book, written in 1906 that details how formaldehyde is used. Before that, it was common trade (craft) knowledge in the making of Galalith. The book I refer to is...Casein; its preparation and technical utilisation by Scherer, Robert; Salter, Charles. Here is the link. archive.org/details/caseinitsprepara00scherich Shellac is a polymer. It is all natural, as it is the secretion of the female Lac bug. You can paint it on, but, it is sold in aerosol form for spraying. Either way will work just fine. Casein is porous. A vacuum is not needed. I plan to spray it on, leaving a clear shine. Yes, you cook the gelatin with the casein. I have not tried it. Perhaps you can do some experiments and share what you discover.

Great video, love the green idea. My question is: you said you spray shellac over it after it has dried completely; do you wait to do this until you have molded and cut it into the desired shape, or before? And how long should one wait until handling heavily? Thanks!
