During a week we created samples of bioplastic with gelatin base, experimenting and testing the limits of this material.
Bioplastic made with gelatin base is a hydroscopic, low temperature biopolymer. It's a simple recipe than anyone can try at home you just need gelatin, glycerol and water. You can find the recipe and the explanations step by step of how to make bioplastic in the pdf "The secrets of bioplastic" at the end of this post.
You can get different harness or (elasticity) depending on the quantity of glycerol you put inside your mixture. You can also change the opacity and the texture by creating foam with spitting air inside the heated mix.
You can try to mix bioplastic with many materials like fabrics, fibers, threads, pigments, tape, wood, metal...
You can also decide to not put any other material than bioplastic and just play with the textures and the patterns you can make.
During our experimentation we discovered than bioplastic : - can take any shape (volume, surface, sheet...) - can have different performance by changing the dosages of water, gelatin and glycerol (elastic -> rigid) - can be transparent & smooth or opaque & fluffy if you add air inside the mix - can dissolve in the water (it is not water resistant) - can be easily recycled and reused by warming it again - don’t smell good (especially when you cook it, once dry the smell begins to fade) - glues to wood, metal, cardboard but not on glass of plastic surface - doesn’t resist the heat (never put bioplastic in the oven, it will melt !) - if you create a large volume of bioplastic it will tend to mold - it will shrink and change its shape while it dries (use a frame if you don't want it to lose it's shape)
