Ceramic Frit Process

Thermosol glass ceramic frit glass is made by printing ceramic frit on float glass by a silk screen process before tempering or heat strengthening.

Ceramic frit process.

Ceramic fritting is a process by which glass enamel is fused on the glass surface. Ceramic enamel frits contain finely ground glass mixed with inorganic pigments to produce a desired color. Ceramic frit manufacturing process 50 silicone 50 water solution is sprayed roller coated or curtain coated onto glass and dried by evaporation of water either ambient or oven curing the silicone to the surface of the glass. After tempering or heat strengthening the glass enamel becomes a permanent coating which cannot be further damaged or removed by cleaning scrubbing etc.

However not all glass that is fused and quenched in water is frit as. The inks used in digital printing on glass mimic the cmyk color model and are made of ceramic frit and inorganic pigments and elements. The ceramic frit is then fused onto the surface of the glass during the toughening or heat strengthening process creating a permanent bond to the glass surface. The coated glass is then heated to about 1 150 f fusing the frit to the glass surface which produces a ceramic coating almost as hard and tough as the glass itself.

A frit is a ceramic composition that has been fused quenched and granulated frits form an important part of the batches used in compounding enamels and ceramic glazes.

According to the website for oldcastle building envelope a building company that supplies frit glass ceramic enamel frits contain finely ground glass mixed with inorganic pigments to produce a desired color the coated glass is then heated to about 1 150 f fusing the frit to the glass surface which produces a ceramic coating almost as hard and tough as the glass itself. Before the glass is heat strengthened or tempered ceramic frit is applied to the glass through a fine mesh screen with glass enamel.

Silk screening is done. This process known as fritting was developed to render any soluble and or toxic components insoluble and or nontoxic. The purpose of this pre fusion is to render any soluble and or toxic components insoluble by causing them to combine with silica and other added oxides. Standard patterns high performance glazing inc.

Moiré is not a defect in the glass silk screen or digital printing process but rather a pattern formed by the eye. After heat strengthening the ceramic frit fuses into the glass and becomes a permanent coating that cannot be removed or damaged by scrubbing or cleaning. It is formed when two regularly spaced non aligned patterns overlap.
