FIELD: glass industry. SUBSTANCE: method of chemical glass frosting involves preliminary treatment in soda solution, frosting glass, neutralization in sulfuric acid solution, washing off in water. Frosting glass is carried out in the mixture containing ammonium fluoride and hydrofluoric acid at the following ratio of components, vol.%: ammonium fluoride 62.5-63.5, and hydrofluoric acid 37.5-36.5. Method can be used in semiconducting technology, glass industry. EFFECT: increased output of process (up to 225 articles/h), retained frosting glass quality.
