This category is for non-commercial sites focusing the techniques of Soda or Salt glazing. Salt-glazing is a once-fire technique where common salt is added to the kiln at the end of a firing, forming a glaze on any exposed surface of the work. The result produces an “orange-peel” effect. Soda-glazing is a chloride-free alternative to salt-glazing. Sodium carbonate or bicarbonate is added into the kiln at a high temperature to create soda-vapor resulting in a variety of surface effects.
