gallnuts

Ingredients

ground gallnuts, water, bran (optional)

Preparation Steps

Original Recipe Text

To remove oil, sprinkle ground gallnuts (about two ounces) over the material. Spread it with your hands, wet and dry. Place in a basin of water, weigh it down, and let it stay for a night or a day. Take it out and rub it vigorously. Adding bran is more effective.

Evidence

"If you want to remove the oil from it, take ground gallnuts and sprinkle the gallnuts over all of it, about two ounces, and spread the piece between your hands and spread the gallnuts over all of it, wet and dry, and return some of it to the other, and return it to a basin in which there is water that covers what you have placed in it, and weigh it with something so it does not go away $^{(1)}$, and let it stay for a night or a day $^{(2)}$ until evening, then take it out of the water and rub it vigorously, and if you can put some bran on it, it is more effective."

Remarks

The nature of gallnuts in leather is that if it is soft, it hardens it, and if it is hard, it relaxes it, and if it has oil, it removes its oil, and if it is not oily, it attaches to the oiliness.
