Soda firing is an atmospheric firing technique where "soda" (sodium carbonate) is introduced into the wood fired kiln near top temperature (2350°, Δ10). The soda combines with the silica, alumina, iron, and other elements in the surface of the wares to produce a glazed or flashed surface. The soda (sodium carbonate) vaporizes and is carried on the flame throughout the kiln. The soda vapors create a glaze when it lands on a piece. Wherever the flame goes so does the soda.
