Victorian Salt Glaze Jar

Traditional salt glaze stoneware jar. Carefully potted with chamfered base and collar rings, this pot has a lustrous finish even finish. Slight sagging to the neck in firing. Otherwise, in excellent, clean condition.

High quality salt-glazed stoneware was produced in Derbyshire, Nottinghamshire, London and Staffordshire from the 17th century.

The salt glaze is formed on the unglazed body by reaction of common salt with the clay body constituents, particularly silica, toward the end of firing. The body should ideally be richer in silica than normal stoneware, and iron impurities can help produce good salt glazes. The introduction of environmental clean air restrictions led to the demise of widespread use of salt glazing.
