How are frosting jars made?
The frosted jar is a glass-colored glaze powder adhered to a certain size area on the product glass. The glass bottle factory is baked at a high temperature of 580~600 °C, so that the glass-colored glaze coating is condensed on the surface of the glass, and shows that it has the same characteristics as the glass. A decoration method of different colors of the main body. Adhesion to glass-colored glaze powder can be applied with a brush or a rubber roller. After silk-screen processing, the floor-to-ceiling pattern of the frosted surface can be obtained. The method is: on the surface of the glass product, silk screen a layer of patterns composed of a melt inhibitor.
After the printed patterns are air-dried, the frosting process is stopped. Then after high temperature baking, the frosted surface without the pattern pattern will be melted on the glass surface, and the center of the silk screen pattern will not be melted and separated from the glass surface due to the effect of the melt inhibitor. After baking, the transparent floor-space pattern is revealed through the translucent sand surface, forming a special decorative effect. Frosted screen printing flux inhibitor, which is composed of ferric oxide, talc, clay, etc., is ground with a ball mill, the fineness is 350 mesh, and is blended with a binder before screen printing.
