ABSTRACT:
A method for preparing a decorative glass using a glass etching composition, wherein a frosting of elaborate patterns and designs is applied on the surface of the glass having an arbitrary shape, such a plane, a curved plane or a tube, by utilizing the silk-screen process or the like, using a glass etching composition characterized as comprising 1 to 20 w/v % (preferably, 2 to 5 w/v %) of a fluoride, 20 to 80 v/v % (preferably, 20 to 50 v/v %) of water and 20 to 80 v/v % (preferably, 50 to 80 v/v %) of an organic solvent miscible with water or another glass etching composition comprising the former composition and an additive. The glass etching composition is free from the problems of the danger to a human body and environmental pollution.
