Description
A substance that assists in the fusing of minerals, metals, ceramic glazes, or glass. A flux may lower the melting point, minimize surface tension, coagulate impurities or prevent the formation of oxides. Examples of fluxes are:
- Alkaline fluxes (used for glazes, glass): sodium carbonate (soda), white lead, red lead, potassium carbonate (potash), borax, sodium oxide, potassium oxide, and lithium oxide.
- Acidic fluxes: sodium bisulfate, potassium bisulfate, and boric oxide.
- Oxidizing fluxes: sodium nitrate, sodium peroxide, and sodium chlorate.
- Reducing fluxes (used in soldering and welding): sodium carbonate, borax mixed with activated charcoal.
