Ceramic Fritting is a process by which glass enamel
is fused on the glass surface. Before the glass is heat strengthened or tempered, Ceramic frit is applied to the glass through a fine mesh screen with glass enamel. After tempering or heat strengthening, the glass enamel becomes a permanent coating which cannot be further damaged or removed by cleaning, scrubbing, etc. Silk-screening is done by printing a layer of ceramic ink on the glass surface through a screen mesh. When silk-screened glass is combined with clear, tinted, Low-E, or reflective glass, it can control light transmittance and reduce solar heat gain while enhancing aesthetic and performance characteristics. Though normally suitable for IGUs, silk-screened glass can be used for both exterior and interior applications. When used on building exteriors, the painted surface must be protected from direct contact with the environment.
Back painted glass is a unique use of glass that has been growing in popularity in recent years.
It is essentially exactly what it sounds like- glass that has been painted on the back side. That way, from the front side, the glass is no longer translucent, but instead a solid color.
