Sodium Silicate is a chemical used in a variety of industries, such as in car exhaust and head gasket repair, sand casting and as a component in drilling fluids. It is also used as an adhesive in the production of cardboard and when bonding glass.
In the pottery industry, sodium silicate is mainly used as a deflocculant during the preparation of casting slips. It reduces the viscosity of the slip, preventing need for a large volume of water to liquidise the clay. It is often used alongside Soda Ash in the creation of casting slips.
There are other uses for sodium silicate in the pottery industry. These include creating a cracked effect on bottles or vases and the creation of ‘magic water’. This is used to join pieces of clay together, especially if the pieces have different moisture levels.
