At the beginning of tanning, take the skin first, remove its hair scale, and ensure cleanliness. It is soaked in the liquid containing aluminum sulfate. The concentration of the liquid and the time of soaking are all fixed. If the concentration is improper, or the length of time is inappropriate, the skin shall not be tanned. When soaking the skin, it is necessary to turn it often, so that all parts of the skin can be matched with the liquid, and the tanned quality is uniform.
When soaking the skin, take out the skin and drain the liquid. At this time, the skin is already slightly tanned, but it is not perfect. Let the skin dry in a ventilated place until it is half dry. After it is half dry, knead it again to make the fibers of the skin soft. After kneading it, dry it again. If it is repeated, the skin becomes tough and smooth, and it can be used.
