Corning Museum of Glass

The Corning Museum of Glass has a very large collection of ancient glass. Many of the pieces have been repaired and restored over the 65 years of the museum’s history, especially since there was a devastating flood in 1972.

Traditional materials such as epoxy and polyester resin were used in the early years of conservation, but since 1993, almost all of the ancient glass has been re-treated using Paraloid B-72 adhesive.

Epoxy resin is still used, especially for filling losses, and new techniques have been developed including “detachable restorations”, which are not as damaging as previous direct castings.

Other new techniques and materials are being used, especially the casting of Paraloid B-72 into films that can be shaped, cut, and inserted for losses.
