1. KERATIN POWDER & TAPIOCA¶

a.	b.	c.	d.
Keratin powder	Tapioca	Glycerol	Distilled Water
60 g	50 ml	5 g	120 ml

glass jar, weight, spoon, magnetic stirrer, baking paper, acrylic sheet or wooden board

Turn on the magnetic stirrer and place the glass jar with the distilled water on the top - turn on preheating.
Turn it on 300-500 rpm and slowly add keratin powder - spoon by spoon. Wait till it will dissolve and add more powder. You can also add citric acid and glycerol.
Stirr the solution at 60-70'C for 2 h so all the ingredients will be well mixed.
Let it cool down and mix it with the tapioca powder. You can play with the mixture with your hands to check if it forms solid paste.
Place the biocomposite into a syringe and place it to the holder.

The biocomposite did not hold its shape and disintegrated. Do not recommend. However I used it after for bioplastic recipe.
