imitation parchment

A type of relatively strong paper first produced by W. E. Gaine in 1857. It is made entirely of chemical wood pulp and is called imitation parchment in order to distinguish it from parchment paper made in imitation of true (animal) parchment. Imitation parchment now bears little resemblance to that paper, nor does it possess any of its qualities. The paper may be rendered partially transparent, greaseproof, and somewhat waterproof by prolonged beating (hydration) of the pulp or by treating the paper with sulfuric acid. The usual basis weight is 30 pounds (24 X 35�). (17 , 156 )
