Salt glaze, in ceramics, a glaze having the texture of
orange peel, formed on stoneware by throwing common salt into the kiln at
the peak temperature. Sodium from the salt combines with silica in the
clay to form a glassy coating of sodium silicate.
"Many thousands of tons of shipping, and seamen in proportion, which in summer trade to the northern seas, are employed in winter in carrying materials for the Burslem ware; and, as much salt is consumed in glazing one species of it, as pays annually near £5,000 duty to Government."
