Salt Firing and Soda Firing
In this section, ceramic artists will share the results of their experimentation with the salt and soda firing process. You’ll find everything from firing schedules to glaze recipes, to beautiful examples of salt and soda fired work.
And if you haven’t already, be sure to download your free copy of the Soda Firing Techniques, Tips and Soda Glaze Recipes, which includes soda firing information for the studio artist – professional or amateur, student or teacher.
Salt firing is a vapor-glazing process where salt (sodium chloride) is introduced into kiln firebox at high temperature. The salt vaporizes, and sodium vapor combines with silica in clay surface, forming extremely hard sodium-silicate glaze.
Soda firing has been touted as modern-day nontoxic replacement for salt firing, but has proven to be much more than that. Potters have discovered that soda firing has endless exciting aesthetic possibilities rather than just being a more environmentally friendly! In the soda firing process, soda ash (sodium carbonate) in water solution, instead of salt, is sprayed into kiln at maturing temperature, and sodium vapor combines with silica in clay to form sodium-silicate glaze.
