Novel chemical compositions for the roughening of the glass, new acid etching baths, roughening of the glass object and frosted

摘要

Composition, characterized in that it comprises 20% to 99% by weight of potassium bifluoride and 1% to 80% by weight, of at least one water-soluble salt of multivalent cation. A solution of frosting glass which can be obtained by dispersing the composition in the water or in an acid solution without the hydrofluoric acid. A solution of frosting glass which can be obtained by dispersing 0, 1 kg to 4, 95 kg of potassium bifluoride and 0, 005 kg to 4 kg, of at least one water soluble multivalent cation salt per liter of water or per liter of an acid solution without the hydrofluoric acid. Method of frosting and glass objects etched by said method.
