The technique of salt glazing was discovered sometime in the 14th century in Germany. The process was originally used with low-fire ceramics, but quickly became a favorite technique with stoneware. Western Europeans used the salt glaze process in salt kilns quite extensively during the 16th and 17th centuries.
Americans have produced salt ware since early 1700s in Pennsylvania, Virginia and American Stoneware became the predominant American houseware during the 19th century. Today, North and South Carolina are well known for continuing salt fire production.
Salt firing is one ceramic process that was created outside of Japan and carried to their culture in the early 1900s. This method is one that is continuing to be used for experimentation and creativity in the field of ceramics and pottery. Modern potters and ceramists continue to explore many of the old techniques. One should keep in mind that this method is hard on contemporary electric kilns in that the fumes are corrosive and destructive to the kiln interiors. Most craftsmen opt to use gas kilns, specialty or home made kilns when using various salt methods.
