In 1991, Jared Bark wrote this article on glazing materials for framers and for designers and preparators in museums and galleries. The glazing market was chaotic in the 1980’s and early 90’s, and this text was an attempt to clarify the field. The marketplace for these products has continued to change rapidly, though in a more orderly way, since the article was written; where products and vendors have come on the scene or disappeared, updates have been made. Otherwise, the data in the 1991 is still accurate and has not been altered.
