Abstract

A selective doping technique allows localized heating of glass for the purpose of sealing, shaping, joining, etc. As shown in A and B, a bead of glass is doped with copper or iron to make it infrared absorbent. The bead is subjected to infrared radiation, becomes softened, and by conduction melts the glass beneath it, thus allowing the bead to sink into the substrate. The resulting inlay defines a sharp interface. In C, two glass plates are joined via intermediate spots of doped infrared absorbent glass when subjected to irradiation. In D in a forming application, a line of doped infrared absorbent glass is applied across a glass plate. When subjected to infrared radiation the plate is caused to bend along this line.
