Designing of Unconventional Applications and Firing Methods to Obtain Salt Glazes

Abstract

Salt glazes are characterized by high aesthetic effects, and are admired by many potters. To get salt glazes must be burnet in a furnace dedicated to the fire of salt glazes. Because salt glazes are formed when the products are burnet at the degree of maturity, then turn off the kiln, and throw salt (sodium chloride) In the kiln, when the salt moistened with water meets the heat inside the furnace, the salt evaporates and turns into sodium oxide, which in turn reacts with the silica and alumina in the body and forms a transparent salt glazes colored by the body color, and hydrogen chloride is evaporated and moved the color from one place to another in the kiln. There are unexpected effects on the objects and sometimes crystallization of salt glazes if accurse appropriate factors are available. Though practical experiments the researcher could obtain the effects of salt glaze by other nontraditional methods. This identified or developed by different methods of firing and applications. The salt was applied directly to the surface of the products after which methods and then the fire in a normal kiln (the fire was in a tunnel kin for sanitary fire at a temperature of 1260 ° C), Results were obtained close to the traditional results of the salt glazing of a variety of texture and color, except for the salmon color characteristic of the salt glaze because it appears with the traditional fire of salt glaze as a result of the atmosphere of the reducing fire ,and because the experiments were carried out in an oxidized atmosphere did not show this color.
