In a salt firing, salt is introduced into the kiln between 2250 and 2350 degrees Fahrenheit. The salt volatilizes and the sodium chloride splits into sodium and small quantities of chlorine gas. The chlorine combines with moisture to form hydrochloric acid which escapes into the kiln atmosphere and exits through the chimney, while the sodium combines with aluminum oxide and silica oxide in the clay, forming a glaze on any exposed surface of the work. Often a typical 'orange peel' effect occurs. A liner glaze that is food safe was used in these works.
