Glass and Ceramics

This group covers the batch raw materials, fluxes and body auxiliaries used in glass, ceramic, glaze and enamel production.

Batch and melting aids

• Soda ash in light and dense grades, the dense grade being preferred in glass production for low dust loss and easier dosing.
• Sodium silicate solutions in modulus 2, modulus 2 at 40 Baume and modulus 3, potassium carbonate as a flux and refined sodium sulfate.

Glaze, enamel and body raw materials

• Borax decahydrate and boric acid as boron sources for glass, ceramics and enamel, barium carbonate for glazes, frits and enamel, and potassium sulfate.
• Zinc oxide in Gold Seal and White Seal 99.7% grades for ceramic glazes.

Deflocculants and binders

• Sodium tripolyphosphate in powder and low-density granule form, tetrasodium pyrophosphate and sodium hexametaphosphate as dispersants in ceramic slips.
• PEG 4000 as a ceramic and metal casting binder.
