How to depilate and cook sheepskin at home?

Preparation of nitrate solution: dissolve 10 kg of sodium sulfate (mirabilite) in 100 kg of water, then add 25 kg of flour and stir evenly.

Nitrification: soak the softened fur in nitrate solution, stir and soak it evenly, press the organism to immerse it under the liquid surface, and turn it once a day. The curing time depends on the temperature. After soaking for about 15 days, you can hang the cylinder. The inspection method of the finished product is to fold the leather board in half or squeeze the nitrate solution by hand. If the hide is white and dehydrated well, it means it has been nitrated.
