Leather

alters the protein structure to preserve for use

hair has been removed, epidermis remains

-hide must be dehydrated with salts or brines to prevent decay -hair must be removed at the tannery

-hide soaked in water to remove materials and rehydrate the skin -hair removed through liming -hairless hide is washed and delimed and pickled to preserve suppleness -”tanning” comes from tannic acid/tannins found in plants -displaces water in the protein of the skin and joins the skin fibers together -leather than dried and rehydrated to 20% moisture, then stretched and softened

very thick- strap leather
