ELECTROSTATIC METHOD OF COATING GLASS ARTICLES WITH A POWDER OF GLASS ENAMEL TO SIMULATE A BLASTED OR ETCHED APPEARANCE

摘要

METHOD OF SIMULATING A SANDBLASTED OR ETCHED APPEARANCE ON GLASS ARTICLES A method of simulating the appearance of a sandblasted or chemically etched surface on a glass article. A glass enamel which includes both a glass frit component and an inorganic pigment component is prepared in dry powder form, and is applied to the heated article by the electrostatic dry powder spray process. After coating the article is fired to fuse the frit, but the firing is carried out incompletely and at a temperature insufficient for the frit to flow out as smooth continuous film, so that the enamel presents a matte appearance.
