kaolin or china clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing al₂o₃.2sio₂.2h₂o.

kaolin was first discovered in the mountainous province of kiangsi, china in a.d. 500. The word "kaolin" derives from the chinese character 'kao lin' which means high ridge. It was first used by the chinese to make high quality porcelain.

at ashapura china clay, processed or refined kaolin is available in white powder form, granule cum powder form, and in lumps form. The various grades and their applications are:

The chemical compound silica, also known as silicon dioxide, is the oxide of silicon, chemical formula SiO₂. Siliceous is an adjective meaning "referring to silica".

Silica is found in nature in several forms, including quartz and opal. In fact, it has 17 crystalline forms. The most common constituent of sand in inland continental settings and non-tropical coastal settings is silica, usually in the form of quartz because the considerable hardness of this mineral resists erosion. However, the composition of sand varies according to local rock sources and conditions.

At Ashapura China Clay, processed or refined silica sand is available in white powder form. The various grades and their applications are:

Dolomite is the name of both a carbonate rock and a mineral consisting of calcium magnesium carbonate (CaMg(CO₃)₂) found in crystals.
