Rare Len Castle Salt Glaze Pottery Lamp Base

• Oviform /ovoid - The outline loosely resembling the shape of an egg.
• Salt Glazed - Salt glazing involves throwing salt into the kiln when it is at its highest temperature, usually around 2,300 to 2,400 degrees Fahrenheit (1,260 to 1,320 degrees Celsius). The salt vaporizes and forms a glaze on the surface of the pottery, creating a range of effects depending on how the salt is applied and the firing conditions. This glazing method was first developed in Germany in the 15th century and quickly became popular throughout Europe and North America. It was particularly popular for making stoneware pottery, such as jugs, crocks, and other utilitarian objects.
  
  Salt glazes can produce a range of colors, including gray, brown, blue, and even pink or purple in some cases. The texture of the glaze is typically rough and pebbled, with a matte or satin finish. The process of salt glazing can be unpredictable, with variations in temperature and salt application leading to subtle variations in the finished product.
  
  Salt glazing is still used by potters and ceramic artists although it is less common than it was in the past.
