What is ceramic frit glass?

Ceramic Fritting is a process by which glass enamel is fused on the glass surface. Before the glass is heat strengthened or tempered, Ceramic frit is applied to the glass through a fine mesh screen with glass enamel. Silk-screening is done by printing a layer of ceramic ink on the glass surface through a screen mesh.

Does spandrel glass need to be tempered?

Spandrel glass must be HEAT TREATED to withstand high thermal stress. If the Spandrel is intended for an opening where safety glass is required by law or code or where human impact is a concern, the glass substrate should be TEMPERED.

What does glass frit do?

Glass Frit Bonding During the cooling process, a strong hermetic wafer bond is formed. At the bonding temperature the glass is soft enough to flow and cover surface steps and roughness, such that the glass frit acts as a planarizing and sealing interlayer between the two wafer surfaces to bond.
