 + ===== Recipes =====
 +
 +  * Gelatine powder 48 g
 +  * Cold Water 240 ml
 +  * Glycerol 12g
 +
 +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.
 +
 +
 + ===== Preparing =====
 +
 +01. First of all I prepared very well a clean ambient and  glass surfaces to receive the bioplastic.
 +
 +02. I dissolve the gelatin powder in cold water, putting first the gelatin in the pan and after the water, stirring with a spoon and adding water until the gelatin dissolved as better as possible.
 +
 +03. Than I turn on the fire of the cooker and heated the mixture until the solution was clear, or all the gelatine dissolved.
 +
 +04. After I poured the liquid over the glass in a thin layer.
 +
 +05. While it was still warm I put some drops of a mixture made with cochineal to tint the bioplastic and over 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.
 +
 +06. After that I let they dry from one day to another, than pulled them up from the glass and let they dry for one more day, hanged in a clean wood surface, changing during the day , the point of hanging, to let they dry regularly.
 +
 +07. After three days, the structure was not changing anymore, and the material was very interesting,​ with a good aspect and very easy to manipulate. ​
 +
 +The process can be seen in the video below.

 +===== Relation between the recipe ingredients and the 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.
