Soda glaze has been praised as an alternative to salt glaze, and steam glaze is also one of the main creative methods of modern ceramics. The development potential of soda glaze in ceramic creation has exceeded the simple purpose of replacing salt glaze.

Basic information

This is a ceramic firing process. After the unglazed ceramic body reaches a certain temperature, baking soda powder or soda water is put into the kiln. When the soda evaporates, a special chemical atmosphere is formed in the kiln, and a glass glaze layer is formed on the surface of the ceramic body. Soda glaze is a ceramic firing method evolved from salt glaze.

It is said that the air pollution and toxicity are great when the salt glaze is fired. During the period of 1970s, a graduate student of Alfred University in new york, USA, successfully developed the firing process of replacing salt glaze with soda glaze.
