SODA ASH GRADE 100 NATURAL: 1 Pound
GRADE 100 SODA ASH for sale (a.k.a. soda ash light) - Na2CO3 (m.p. 900o F/490o C) anhydrous sodium carbonate is a very active flux for low temperature glazes (below cone 5). However, it is water soluble and is generally used in fritted form to prevent recrystallization in the glaze suspension. Glazes which use raw Soda Ash should be well-ground and used immediately, or dry-ground and only the amount needed mixed with water. Soda Ash is also used in small amounts as a deflocculant (see Darvan #7) in clay slips to reduce the amount of water needed to make the slip fluid. Sodium bicarbonate (NaHCO3) can be substituted as a deflocculant for Soda Ash, however, the amount should be doubled.
