What is pottery salt glaze?

Pottery salt glaze is a type of glazing technique used in pottery that involves the application of salt vapor during the firing process. Salt is introduced into the kiln at a high temperature, and it reacts with the silica in the clay body, forming a layer of glaze on the surface of the pottery. This technique creates a distinctive, mottled surface with a slight orange-peel texture, which is highly sought after by collectors and enthusiasts.

Salt glaze pottery originated in Germany in the 15th century and was widely used for the production of household items such as crocks, jugs, and other storage vessels. In the 18th century, salt glaze pottery became popular in England and was used for more ornamental items, including figurines and teapots.

Today, salt glaze pottery is still widely produced and valued for its unique texture and appearance. However, the use of salt glazing in pottery production has declined due to concerns about environmental pollution and workplace safety.
