Bentonite

Just 1% bentonite has a suspending strength almost equivalent to 5% kaolin or ball clay. So if your glaze contains 0–5% clay, then it will likely need 2% bentonite to keep it in suspension. If your glaze contains 5% clay or more and it's having trouble staying suspended, 1% bentonite is probably all it will need to stay in suspension.

Furthermore, as a traditional and still popular ceramic product, how the property of fired clay bricks is influenced by kaolinite defects remains unclear, although kaolinite is one of the most essential clay minerals in raw materials for brick making [21], [22], [23]. A lack of this knowledge makes it challenging to select appropriate raw ...

Fluxes

In ceramics, the addition of a flux lowers the melting point of the body or glaze. In particular they affect the melting point of silica (SiO 2), which melts to form a glassy phase during firing/sintering which bonds the ceramic body or forms the basis of a glaze.The addition of a flux also promotes fusion or vitrification (formation of a glassy …

Working with Ash in Glazes

Ash can be added unwashed or washed to a glaze mix as a dry ingredient. It can also be mixed with water to make a wash, and sprayed or brushed over a glaze. The advantage of using washed ash is the removal of soluble sodium/salt. Since ash is a variable material, we can at least remove the soluble sodium.
