Abstract
There is disclosed a method of producing a transition metal pattern on a glass or glass-ceramic substrate by selective exudation of a transition metal from a glass substrate containing the metal as an oxide. The selective exudation is effected by applying an intense, well-focused source of energy to a glass in a pattern corresponding to the desired metal pattern. This develops localized heating, and thereby causes corresponding localized metal exudation from the glass. The metal pattern may be rendered electroconductive, and may constitute a pattern of interconnecting lines for microcircuitry.
