FIELD: chemistry.
SUBSTANCE: invention relates to compositions of enamel coatings for depositing on objects made from silver based alloys. The enamel coating contains, wt %: PbO 46.0-48.0; K2O 4.0-4.6; ZnO 0.2-0.3; B2O3 4.0-6.0; Sb2O3 0.02-0.04; Ag 0.05-0.2; Na2O 0.5-1.0; SrO 2.0-3.0; CaO 1.0-1.5; SiO2 38.36-39.23. The enamel coating has adhesive strength of 0.03 kgm.
EFFECT: increased adhesive strength of enamel with the surface of objects made from silver based alloys.
