After a few days of experimenting with various plastics, re-cycling, dissolving and casting, cooking and buring, i want to share some of the experiments on the Casein Plastic, aka Galalith, aka Milkstone, in this thread.
we started to collect first instrucitons and links in an earlier general topic and on the wiki.
During the preparation and the workshop we explored different “fat contents” of milk, seems like the lowest fat milk gave the best results. Also adding “plastisizer” such as glycerol seems to make it more malleable. The drying of the casein plastic still needs a lot of time, so it’s not something to do in a short workshop, can take days… also the final cross-linking using e.g. formaldehyde is a bit questionable due it’s carcinogenic properties. There seems to be less dangerous alternatives using Acetaldehyd, tannic acid or natural enymes (transglutaminase), definately something to look further into.
We also explored to by this big pots of extraced “100%” Casein used for muscle dietary uses. but it has loads of other stuff in it for taste and emugators… we see what we can do with it.
Other great resources we explored:
- Galalith in fashion
- Industrial Bible of Galalith from the 1906 “Casein; its preparation and technical utilisation”
- There is a lot of recent interest in using casein in food packaging. just google: “Edible food packaging made from milk proteins”
