Kovar, Steel, and Corning Specialty Glass 7056
2’1”h x 2’4”w x 1’5”d
The glass element was created during the Corning Museum of Glass/Corning Incorporated Specialty Glass Residency Program in Corning, New York. During the year-long residency, Albert Paley explored furnace-working and casting of Corning Specialty Glass 7056, a borosilicate glass that was engineered to bond tightly to a metal alloy called Kovar. Corning 7056 is used industrially in special electronic circuit packages that need the durability of the metal, and the transparency of glass, with a perfect, air-tight seal between the two. The coefficient of expansion for the materials is the same allowing an integral bond of the specialty glass and the Kovar. This is not possible with traditional materials.
