ABSTRACT:
A means of permanently characterizing a glass workpiece (1) which is subjected to a heat treatment period during processing. An organic paint is utilized to apply identifying characteristics (3), and an inorganic bake-on paint is used to create an opaque permanent layer (5) in the region of the identifying characteristics (3). Heat treatment is utilized to create surface marks (4) on the workpiece (1) from the vaporization and burning of the organic paint into the inorganic paint.
