Tannage, the process of turning animal hides into leather, can be described using a variety of synonyms. The first synonym that comes to mind is "tanning," which is the process of treating the hide with chemicals to preserve it and give it a certain texture. Another synonym is "leather-making," which encompasses all aspects of the process, from rawhide preparation to finishing. "Curing" refers specifically to the preservation of the hide, while "tawing" is a type of tanning that uses alum salts to create a softer, more pliable leather. Finally, "chroming" is a modern method of tanning that uses chromium salts for a faster, more efficient process.
