Saggar atmosphere, or concentrate the effects of salts, metal oxides and other materials on the surface of their ware. Some pots may be carefully prepared for saggar firing. One method creates a smooth surface covered with clay slip, terra sigillata, which responds particularly well to the saggar technique. This slip covering may be burnished to achieve a gloss.

These materials ignite or fume during firing, leaving the pot buried in layers of fine ash. Ware produced in filled saggars
