Salt glaze is a ceramic glazing technique that involves adding salt to the kiln during the firing process. When the salt vaporizes, it reacts with the silica in the clay, forming a glossy, textured surface. This method is often used for stoneware, giving it a distinctive, rustic appearance. The salt glazing process typically occurs at high temperatures, around 1,200 degrees Celsius (2,192 degrees Fahrenheit). The result is a durable and water-resistant finish, making salt-glazed pottery ideal for functional items like jugs, bowls, and tiles. This technique has historical roots in various cultures, particularly in German and English pottery traditions.
