Abstract

On an electric insulator of porcelain (2), in particular an electric high-voltage insulator, with at least one opaque, 0,1-1 mm thick glaze layer (3), is a film (4), which consists mainly of tin oxide, SnO2, deposited on the said opaque glaze layer, wherein the tin oxide film deposited on the glaze layer has a thickness that is considerably less than that of the glaze layer. The tin oxide film can be deposited onto the glaze layer after completed firing at a temperature of between 1150 and 1450 DEG C in the firing kiln, when the temperature of the glaze layer has decreased to a temperature below the softening temperature of the glaze layer, preferably to a temperature between 300 and 800 DEG C.
