The production and dyeing of any clothing material must be carefully regulated to protect the environment. Fur tanning (‘dressing’) and coloring, however, are designed to preserve fur hairs and follicles, rather than remove them from the hide, as in leather tanning. The main chemicals are alum salts, including aluminum sulfate. These are quite benign chemicals, as they have to be to protect the fur. Alums have been used for hundreds of years for water purification, to reduce the pH of garden soil, and for medicinal uses. Aluminum sulfate is the active ingredient in many antiperspirants and it is used in styptic pencils to stop bleeding when shaving and to relieve pain from insect bites. We also use regular table salt (NaCI), lanoline and other natural ingredients.
