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.
Available in C100, C140 and NS 75 Grades
Preparation & Safety
Health & Safety: This is a chemical product and can be corrosive or irritating. Always wear appropriate PPE, including gloves and eye protection, and ensure the area is well-ventilated. Refer to the Material Safety Data Sheet (MSDS) before use.
Pottery Use: Often used in conjunction with Soda Ash to create casting slips.
Compatibility: Used across various industries including car repair (exhausts/head gaskets), sand casting, drilling fluids, and as an adhesive for cardboard or glass.
Application
Deflocculant (Pottery): Used to reduce the viscosity of casting slips, allowing clay to liquidize without the need for large volumes of water.
“Magic Water”: Can be mixed with water to join pieces of clay together, particularly useful when bonding pieces with different moisture levels.
Decorative Effects: Applied to pottery to create a cracked effect on items like bottles or vases.
Adhesive: Used for bonding glass or in the production of cardboard.
Industrial Repair: Applied as a component in car exhaust and head gasket repair systems.
Overcoat: N/A. Usage varies by industry (e.g., pottery, adhesive, or industrial repair).
Theoretical Coverage: N/A (Usage rate determined by specific industrial application or mixture).
(Coverage rate can be affected by such variables as type and condition of substrate, type of application equipment and individual method of application.)
Thinning and Cleaning
Thinning: Liquid solution. Can be diluted with water depending on the application (e.g., creating ‘magic water’ in pottery).
Cleaning: Clean all equipment immediately after use with water.
Q: What is the main purpose of Palatine Sodium Silicate?
A: Sodium Silicate (water glass) is a versatile chemical used across many industries. Its primary uses include car exhaust and head gasket repair, sand casting, adhesive for cardboard, and as a component in drilling fluids.
Q: How is it used in the pottery and ceramics industry?
A: It is mainly used as a deflocculant to reduce the viscosity of casting slips, allowing the clay to liquidise without needing large volumes of water. It is also used to create “magic water” for joining clay pieces and to create a cracked effect on decorative items like vases.
Q: What safety precautions should I take?
A: Sodium Silicate is a chemical product and can be corrosive or irritating. Always refer to the provided MSDS (Material Safety Data Sheet) before use, wear appropriate PPE (gloves and eye protection), and use in a well-ventilated area.
Q: What is “magic water”?
A: In pottery, “magic water” is a mixture using sodium silicate that helps bond pieces of clay together, particularly when those pieces have different moisture levels.
Q: Is it used with other chemicals?
A: In the pottery industry, it is frequently used in conjunction with Soda Ash to create effective casting slips.
