Frosting is to adhere a certain size of glass glaze powder on the product glass. After high temperature baking at 580~600℃, the glass color glaze coating melts on the glass surface and shows a different color from the glass body. A method of decoration. Adhesive glass color glaze powder can be applied with brush or roller. Through silk screen processing, you can get the frosted floor pattern. The method is to silk-print a layer of patterns formed by the flux inhibitor on the surface of the glass product. After the printed patterns are air-dried, frosting is performed. Then after high-temperature baking, the frosted surface without patterns is melted on the glass surface, and the sand surface covered on the pattern cannot be melted on the glass surface due to the effect of the flux inhibitor in the silk-printed pattern. After baking, the transparent pattern of the floor space appears through the translucent sand surface, forming a special decorative effect. Frosted screen printing flux inhibitor, composed of iron oxide, talcum powder, clay, etc., is ground with a ball mill, with a fineness of 350 mesh, and is blended with a binder before screen printing.
