- Ceramic glass
Ceramic glass is made from a controlled crystallization of a base glass to form a polycrystalline.
To create ceramic glass the base glass is heated so that it partly crystalizes. This gives it its high working temperature of 750 deg C. Ceramic glass is also resistant to differing temperatures and can withstand repeated quick temperature changes.
Also glass ceramic usually has a very close to zero thermal expansion coefficients.
Application: Glass Ceramic is predominantly used for cook tops due to its ability to withstand repeated and quick temperature changes.
Their ability to having different heat reduction coefficients means they are perfectly suited for electric stoves whereby sections of the stove remain cold whilst other sections heat up.
Laminated glass or safety glass is a type of glass which holds together when broken or shattered.
This is because of a special film in between two sheets of glass. This film is a material called PVB (Poly Vinyl Butyral) which prevents the glass from breaking up into large sharp dangerous pieces of glass.
Application: Laminated glass is used primarily for its safety capability. The most common use is for vehicle windscreens. Other uses include bullet proof manufacturing and airline windows.
4.4, 6.4, 8.8, 10.8, 11.5 and 12.8mm re standard thicknesses.
However any thickness can be made to order.
- Optical White Crown Spectacle B270 Glass
White Crown Spectacle is a clear, high transparent crown glass with very high transmission in the visible light range as well as the infrared and ultraviolet region.
0.9-17mm thickness available from stock.
- Optical Materials
Sapphire, BK7, KG1, Quartz glass, coloured filters all in stock.
- Quartz Corning Vycor Glass
4mm thickness, 900°C maximum working temperature.
- Alkali-Free Glass AF45
Ideally suited for opto-electronic products, available in thin sheets of 0.7 to 1.1mm in thickness.
AF45 is a modified borosilicate glass, alkali free and suitable for flat display applications such as LCD and electroluminescence displays (ELD).
It also serves as an excellent substratum for solar cells and electronic thin film work.
- Optivex UV blocker
The UV Blocker works in a different way to Optivex as it absorbs the UV radiation. Hence the transmission of light is lower and will absorb about 350nm of radiation (not suitable for museum or gallery use; ideally suited for commercial applications where 100% protection is not required).
The maximum temperature is 600°C. Please note the higher the light source, the more UV radiation output. 3mm and 4mm thicknesses available from stock.
