Ceramic frit process.

Silk screening is done. Before the glass is heat strengthened or tempered ceramic frit is applied to the glass through a fine mesh screen with glass enamel. 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. This process known as fritting was developed to render any soluble and or toxic components insoluble and or nontoxic.

Standard patterns high performance glazing inc. 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. 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. 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.

Moiré is not a defect in the glass silk screen or digital printing process but rather a pattern formed by the eye. 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. Silk screen ceramic frit patterns consist of holes dots stripes gradients and many other custom designs. After tempering or heat strengthening the glass enamel becomes a permanent coating which cannot be further damaged or removed by cleaning scrubbing etc.

Thermosol glass ceramic frit glass is made by printing ceramic frit on float glass by a silk screen process before tempering or heat strengthening. The development of inks is a highly controlled production process to remove any variability in the final product. Ceramic enamel frits contain finely ground glass mixed with inorganic pigments to produce a desired color. 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.

The inks used in digital printing on glass mimic the cmyk color model and are made of ceramic frit and inorganic pigments and elements. It is formed when two regularly spaced non aligned patterns overlap. Ceramic fritting is a process by which glass enamel is fused on the glass surface.
