Abstract
There is provided a method for adhering precious metal to vitreous substances or bodies. Precious metal (including but not limited to, gold, palladium or platinum) is deposited or applied to the surface of the vitreous body. After such initial application, which may include a preheating step, the outer skin or membrane of the glass is made plastic and sticky by superheating. This change in viscosity allows the glass to bond to the deposited precious metal. The superheating process is completed quickly before distortion of the contour of the vitreous object and unwanted vaporization of the deposited metal take place. After the superheating process is completed, the object is annealed conventionally to room temperature.
