How Leather Is Made
The raw material of leather is the skin, or hide, of an animal such as the cow or horse. First, it is scraped clean of all the bits of fat and flesh on the inside, and then the hair is taken off from the outside. What is left is a clean skin, but one which would soon rot if left untreated. The treatment it gets is called 'tanning'. The two most common forms of tanning are vegetable, or bark, tanning and chrome tanning.
