 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.

 +===== 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.
