Glass, Glazes & Ceramics

Fused Silica, also known as fused quartz, is a glass consisting of almost pure amorphous silica. It has a high working and melting temperature. It has high strength, electrical resistivity, thermal stability and UV transparency properties. It is used in high power vacuum tubes, lithography projection masks, data storage, and refractory applications such as steel making, investment casting and glass manufacture.

Spodumene is a pyroxene mineral and a source of lithia. It is used in glasses, ceramics, porcelain enamels, whitewares and glazes due to its powerful fluxing properties. It has low thermal expansion, reduces the melt viscosity, melting temperature and contributes to brilliancy and strength of the glass.

Petalite, also known as castorite, is a lithium aluminium phyllosilicate mineral. It is used in ceramics, glass and enamels. The addition of petalite improves strength, density, acid resistance, heat resistance and gloss. It reduces melt viscosity, melting temperature and thermal expansion and promotes melt homogenization.

Lithium Carbonate is an excellent source of lithia for use in glazes, ceramics and glass. The addition of lithium carbonate improves strength, density, acid resistance, heat resistance and gloss. It reduces melt viscosity, melting temperature and thermal expansion and promotes melt homogenization. Bisley supplies the Xeolith® range, available with a variety of specifications.

Potassium Feldspar is used as a flux in glassmaking and ceramics. It melts well at temperatures between 600 °C and 750 °C. Feldspars reduce the melting temperature, viscosity and helps create a glassy phase in ceramics. Feldspars increase the hardness, durability and chemical resistance of the finished product.

Green Chromic Oxide is a green pigment used in glass and ceramics. It can be used in temperatures up to 1200 °C.

Manganese umber is a natural brown or reddish-brown pigment that is composed of manganese oxide and iron oxide. Manganese umber is used as a pigment in the production of glass, glazes and ceramics. It is suitable for use in the production of bricks, pavers, roof tiles and many other ceramics.
