During the course of this firing, table salt is introduced into the atmosphere of the kiln. The salt vaporizes in the kiln, and flames spread the vapor. At this time, part of the salt molecules combine with the silica and alumina in the raw clay to create sodium silicate, which provides the coveted orange peel glaze coating on the unglazed portion of the pots.
Salt-fired pots are food safe and can contain liquid. These pots are dishwasher and microwave safe and can also be used in the oven.
