The Soda firing family. A really unique and special firing process with unpalleled results. Soda firing is a dynamic and variable process wherein liquified soda carbonate is sprayed into the kiln at 2,280 F through several ports (openings) on each side. The soda spray immediately vaporizes and is swept up in the path of the flame, painting on the ware and creating a glaze. Each firing results in completely organic and unique interaction of the flame and vapor.
