Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.It is abundant in igneous,  metamorphic, and sedimentary rocks.
Quartz is one of the most useful natural materials. Its usefulness can be linked to its physical and chemical properties. It has a hardness of seven on the Mohs Scale which makes it very durable. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. High-purity quartz sandstone suitable for the manufacture of high-quality glass. "Glass sand" is a sandstone that is composed almost entirely of quartz grains. Much of it has been used for container glass, but some of it has been selected for use in making lenses for the largest telescopes. The high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing. Quartz is very resistant to both chemicals and heat. It is therefore often used as a foundry sand. With a melting temperature higher than most metals, it can be used for the molds and cores of common foundry work. Refractory bricks are often made of quartz sand because of its high heat resistance. Quartz sand is also used as a flux in the smelting of metals. Quartz sand is used as a filler in the manufacture of rubber, paint, and putty. Quartz powder is one of the most important ingredients in glass manufacturing. The high purity and small size of its particles enable the product to be used to produce first-quality glass in bottles, containers, optical glass, etc.  Quartz powder is used in the ceramics industry to improve the properties of ceramic products. It improves strength, decreases shrinkage during firing, and increases thermal stability.Quartz powder functions as both a filler and a thickening agent in the paint and coatings industry. It improves viscosity and texture, enhancing paint durability in its application.
Our quartz powder having low iron and good whiteness. No shrinkage at 1230 degree centigrade temperature. Suitable for glazes, engobes and body preparation of tiles and sanitaryware.

White clay is sedimentary clay having properties of no shrinkage at 1120°C temperature and giving good-fired strength to the tiles fired at low temperature below 1150°C. Because of no shrinkage or expansion, size will not shrink more in firing. Best suited for wall tiles for both single firing and double fast firing. This clay helps in fast degasification in ceramic tiles because of lower loss on ignition (below 4%) compared to any clays.

Feldspars are sodium, potassium and calcium aluminosilicates that constitute 60% of the Earth’s crust. Feldspars of importance to ceramics are aluminosilicates of sodium, potassium and calcium. They are used as fluxes to form a glossy phase in bodies, thus promoting vitrification and translucency. They are also serve as a source of alkalies and alumina in glazes. The pure spars are albite (NaAlSi3O8), orthoclase or microcline (KAlSi3O8) and anorthite(CaAlSi3O8). The soda feldspars are used in glasses and glazes, the high potash feldspars in white ware bodies. Potash feldspar enable the broadest firing range and the best stability of the body against deformation during firing. Sodium feldspar exhibits a lower viscosity than potash feldspar when melted at a given temperature. Feldspars are the main vitrifying or fluxing agents used during the firing process of ceramic bodies. Fluxes melt at an early stage in the firing process, forming a glossy matrix that bonds the other components of the system together, ensuring the durability of firing bodies.
We offer washed potash feldspar with good whiteness. Washed potash feldspar best suited for double charge top bodies and glazes where more whiteness and melting required.
