Al2O3- Responsible for the mattness or brilliance of glazes. Prevents devitrification and adds strength. Insoluble in water and melts at 3550° F. Use of too much alumina can cause a dry appearance. As the intermediated oxide in glazes, it stabilized the combination of fluxes and glass formers, also helps control the fluidity of the glaze.
Many materials used by potters in glazes and clay are potentially hazardous substances. We at Bailey feel you should take precautions to minimize exposure.
1. Handle materials carefully. Avoid spillage. Keep materials covered.
2. Wear a NIOSH approved respirator. Avoid breathing all dusts.
3. Wear rubber gloves when glazing or painting with oxides or stains.
4. Keep your workspace clean, free of dust.
5. Wash your work clothes separately from other clothing.
6. Do not eat or smoke in your workspace.
7. Use a wet mop for cleaning or a toxic dust vacuum cleaner.
