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 )
