The term parchment is a general term for an animal skin which has been prepared for writing or printing. Parchment has been made for centuries, and is usually calf, goat, or sheep skin. The term vellum from the French veau refers to a parchment made from calf skin. The manufacture of parchment is quite involved. After the skin is removed from the animal and any hair or flesh is cleaned away, it is stretched on a wooden frame. While it is stretched, the parchment maker or parchminer scrapes the surface of the skin with a special curved knife. In order to create tension in the skin, scraping is alternated by wetting and drying the skin. The parchment is scraped, wetted, and dried several times to bring it to the right thickness and tautness. Sometimes a final finish is achieved using pumice as an abrasive followed by chalk in order to prepare the surface of the skin to accept ink.
