Special Study Of Glazes

To produce white glaze, transparent glaze is mixed with tin oxide, a common opacifier. It scatters light through the glaze, making it appear white. Other oxides like copper, zinc, and manganese do not produce white glaze.

White Peel forms when rock salt reacts with clay at high temperatures. This interaction creates a natural glaze with a unique textured appearance. Other colors like pink, orange, or purple do not occur in this method.

• Barium Carbonate has the highest melting temperature.
• Soda Ash follows next in melting temperature.
• Tin Oxide melts at a lower temperature than Soda Ash but higher than Silica.
• Silica melts at a lower temperature than Tin Oxide.
• Zinc Oxide has the lowest melting point.

The correct order is: Barium Carbonate > Soda Ash > Tin Oxide > Silica > Zinc Oxide.

Reduction firing creates a low-oxygen atmosphere that enhances the chemical reactions of metallic oxides in glazes, resulting in bright, vivid colors. Other effects like crystalline surfaces or crazing occur in different firing processes.
