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

In the old days, it was a cotton rag paper which was heavily beaten and
then run through a sulfuric acid bath until it began to gell and then run
through an alkaline bath to neutralize the acid.

These days, it means any cellulose fiber which has been really been beaten
to a pulp to the extent that it is translucent.

In general, it does not react with paper which it may come into contact with.
