FIELD: chemistry.
SUBSTANCE: invention relates to the enamel compositions used in coating the cast iron and steel made articles. The enamel contains in mass percent: 44.0-47.0 of SiO2; 15.0-20.0 of Al2O3; 2.0-4.0 of Na2O; 2.0-4.0 of K2O; 2.0-4.0 of CaO; 2.8-4.8 of MgO; 10.0-15.0 of B2O3; 4.0-6.0 of TiO2; 1.0-2.0 of F; 0.1-0.2 of As2O3; 4.0-6.0 of ZrO2.
EFFECT: thermal resistibility of enamel is increased.
