...what does wood fired, salt glazed stoneware mean? Salt-glaze, the result of a reaction between common salt and clay, gives a unique finish that forms an integral part of the ceramic object itself. Salt-glazed stoneware acquires it surface formation and colour not only through the chemical oxide composition of the body before firing and mineralogical-physical structure cootings ( engobes) or painting, but for the most part through the process witch occurs in the kiln at high temperatures and during cooling. Common salt is composed of sodium and chlorine; these are both chemically reactive elements witch combine with other elements, either in the clay or in the atmosphere of the kiln. Sodium when then thrown into a hot kiln acts as a flux or melting agent and acts with the silica in clay to form a soda glass or glaze lower on the surface of the clay. To achieve a high gloss orange-peel salt-glaze, the clay is fired to its vitrification temperature. Our pots are fired in a 3.0 m3 ( 106 cu. Ft. ) CROSS DRAFT KILN. The firing from raw to glazed lasts about 36 hrs (day and night)
