Chrome tanning is a method used to tan animal hides, primarily using chromium salts. This process is popular because it is faster than traditional tanning methods, allowing hides to be processed in just a few days. The resulting leather is known for its durability, flexibility, and resistance to water. During chrome tanning, the hides are soaked in a solution containing chromium sulfate, which penetrates the fibers and stabilizes them. This technique produces leather that is often used in various products, including shoes, bags, and upholstery, making it a key process in the leather industry.
