Tin-based opacifiers in archaeological glass and ceramic glazes…
2018年11月12日 · Tin-based opacifiers and colourants, namely lead-tin-oxide and tin oxide, were used to produce, respectively, yellow and white glass and glazes. They were also used as opacifiers in glass and glazes coloured by other metallic oxides, such as oxides of copper, manganese, and cobalt.
Opacifier - Wikipedia
An opacifier is a substance added to a material in order to make the ensuing system opaque. An example of a chemical opacifier is titanium dioxide (TiO 2), which is used as an opacifier in paints, in paper, and in plastics. It has very high refraction index (rutile modification 2.7 and anatase modification 2.55) and optimum refraction is ...
Silicone Spandrel Glass Opacifiers - Facade Tectonics Institute
Silicone spandrel glass coatings have been examined as a solution to prevent the strength reduction in heat-treated glass when ceramic enamel frit is applied as an opacifier. Four-point bending tests were used to investigate the flexural strength of coated heat-strengthened and fully-tempered glass.

Spandrel Glass | Vitro Architectural Glass - VitroGlazings.com
Unlike vision glass, which is meant to be transparent, spandrel glass is a non‑vision application designed to be opaque in order to help obscure the spaces between the floors of a building, including insulation, vents, wires, slab ends and mechanical equipment.
Tin-based opacifiers in archaeological glass and ceramic glazes: a ...
Tin-based opacification by tin oxide and lead-tin-oxide particles was used in glass production since the first millennium BC and in ceramic glazes since the eighth century AD. Opacification process is often characterised by significant amounts of tin
Traditionally, the opaqueness is created by applying an opaque coating or film to the indoor surface of the glass. Ceramic enamel frits, silicone based paints, and plastic or metal films are typically used as opacifying materials.
