Re: So, what then is "glassine" really?



>From Bookbinding and the Conservation of Books
A Dictionary of Descriptive Terminology

Glassine paper

A supercalendered paper manufactured principally from chemical wood pulps
which have been beaten to secure a high degree of stock hydration. Glassine
paper is grease resistant, has a high resistance to the passage of air, and
is almost impervious to the passage of water vapor. It is also smooth and
transparent, or semi-transparent. It is made in white and various colors,
and may also be made opaque by the addition of fillers. Basis weights range
from 12 to 90 pounds (24 X 36--500), with the ordinary range being from 15
to 40 pounds. Glassine tape, which is the paper backed, with a
water-soluble adhesive, is sometimes used to repair torn book leaves,
although it will eventually turn yellow and may damage the paper. It is
also used in lieu of cellulose acetate in the SUNDEX PROCESS of lamination.
