Introduction to the frosted glass bottle technology

Frosting is a decorative method in which a certain area of glass enamel powder is adhered to the surface of a glass product. After baking at a high temperature of 580 - 600℃, the glass enamel coating melts on the glass surface, showing a color different from that of the glass body. The glass enamel powder can be applied by a writing brush or a rubber roller. Through screen - printing, a frosted hollow pattern can be obtained. The method is as follows: A pattern formed by a melting inhibitor is screen - printed on the surface of the glass product. After the printed pattern is air - dried, the frosting process is carried out. Then, after high - temperature baking, the frosted surface where there is no pattern will melt on the glass surface. Due to the effect of the melting inhibitor, the frosted surface on the screen - printed pattern cannot melt on the glass surface. After baking, the transparent hollow pattern will appear through the semi - transparent frosted surface, creating a special decorative effect. The screen - printing melting inhibitor for frosting is composed of ferric oxide, talcum powder, clay, etc. It is ground by a ball mill to a fineness of 350 mesh and is mixed with an adhesive before screen - printing.
