Salt glazing

Salt glazing is a pottery process where salt is introduced into a hot kiln during firing, typically at high temperatures (around 2300°F or 1260°C). The sodium from the salt vaporizes and reacts with silica in the clay, forming a glassy, often orange-brown surface. This technique creates a unique, durable finish with a slightly textured appearance and enhances the pots' resistance to moisture. Salt glazing originated in Germany and became popular in England, particularly for utilitarian stoneware. The method not only serves aesthetic purposes but also improves the functionality of the pottery, making it suitable for food and drink.
