The invention relates to the enamelling industry, in particular to a mass composition for obtaining a solar irradiance low reflective silicate enamel coating on chromium-nickel steel. The coating obtained reflects less than 10 % of solar irradiance in the wavelength range of 300–2500 nm. The low reflective coating is obtained by further introduction of Cr2O3, Fe2O3 and CuO into mass composition in the following proportion of components (wt % per 100 wt % of frit): frit 100, ground SiO2 30–70, Cr2O3 30–40, Fe2O3 20–30 and CuO 30.
