For a soda glaze firing, pots are raw fired in a gas kiln to Cone 12 over a 30-hour cycle. Reduction commences at Cone 07. The soda is sprayed in as a saturated solution at Cone 8 and there is a 1 1/2 hour soak at the end. A Shino glaze firing lasts approximately 80 hours. Hammond fires 18 hours to 1688F (920C) when a strong reduction commences. Then it is a very slow climb to 2048F (1120C) and then a period of neutral fire to 2300F (1260C). A 5-hour soak is then followed by a slow firing down in reduction to 920C.
