Obs. I have much difficulty in buying glycerol , because here in Brazil it is forbidden, and controlled. The only glycerol I could buy was for skin hydration, that is dissolved in water and not pure, so I calculate the correct amount I should insert , that was the double, because it was 50% solution in water in the origin, and discounted the amount of water from the total amount I should put in the original recipe. | Obs.

While it was still warm I put some drops of a mixture made with cochineal to tint the bioplastic , put some hibiscus petals, in other sample I put some silk threads, in other some dry petals of flowers , in other some saffron in powder and in the last one I overlapped a plastic net to create a texture. | + | 05.

+ | ===== Relation between Glycerol concentration and final results ===== | ||
+ | |||
+ | Ingredients | ||
+ | |||
+ | Distilled Water 100 ml | ||
+ | |||
+ | Gelatin 20 g | ||
+ | |||
+ | Glycerol 5 ml | ||
+ | |||
+ | Resuming the solution should have the following concentrations | ||
+ | |||
+ | Gelatin 20% | ||
+ | |||
+ | Glycerol 5% for the basic Bio-Plastic | ||
+ | |||
+ | We can change glycerol concentration according to need, the more glycerol the more modest the plastic and the more resistant, the less Glycerol the more rigid and more brittle (brittle). | ||
+ | |||
+ | With 3.3% glycerol we have what we call Bio-Resin | ||
+ | |||
+ | and 10% Bio-Silicone | ||
+ | |||
+ | Adding 4% detergent will have the Bio-Foam. | ||
