Bio dyes
For bio dyes, I used animal, protein fibre (80% wool, 20% silk) and vegetable, cellulose fibre (100% cotton) bases. The mordant that I used was Tartaric Acid with hibiscus die, and acidic apple vinegar modifier, with time as a variable as well.
It is important to label each fibre. I used a waterproof plasticized labeler
Important to weight the fibres, and take an average to later measure the amount od mordant to put in
Boil the 8 fibre strips for an hour in the wash with 1 spoon of baking soda.
I separated half to put in a boiling water with 6% of the net weight (0.135g of Tartaric Acid in 500mL of water)
Due to transport, I added the dye after 2 days. I boiled water and then letter it simmer on the hibiscus (around 100mL in half a cup of hibiscus flowers) for 30 minutes. Then I added the fibres and let them simmer for 45 minutes and afterwards left them overnight.
After 14 hours I removed half
After 20 hours I removed the other half
I got half of those, and simmered them in 4 spoons of apple vinegar for 5 minutes, with the hibiscus liquid.
I washed the fibres gently with lukewarm water from the tap, and a little bit of detergent.

-when putting in the dyes, all the fibres were in the same boiling container

Biopolymer
Ingredients: 1 L of milk
1 litre of milk is brought to boiling point
4 splashes of vinegar are added after boiling
Silicon spray is put in the plastic petri dishes (this allows for no stick)
For colorants: turmeric (1:1 ratio with water), 2g of glycerol were added in a full petri dish, 12 g of paprika (in 15ml of water), and completely covered onion skin
