The New Glass Frosting Paste

Russian scientists have developed an acid-free material for frosting patterns onto glass. The paste does not contain hydrofluoric acid or its compounds. The frosting process occurs at around 300 deg C and leads to the modifying of the glass layer under the surface and to the surface with a certain number of cracks created. This structure changes the optical properties of the surface frosted area which becomes a milk-like colour, but the glass surface remains completely smooth. The new frosting paste may be used in the decoration process either separately, or in combination with the etching compositions for common frosting.
