Types of pottery glazes refer to the various types of finishes that can be applied to ceramic pieces to create different effects. Some common types include ash glazes, celadon glazes, salt glazes, shino glazes, raku glazes, matte glazes, glossy glazes, and crystalline glazes. These glazes are made from raw materials such as feldspar, quartz, kaolin, metal oxides, carbonates, and other ingredients, and are fired at different temperatures and atmospheres to achieve the desired results. Different glaze application techniques, firing methods, and cultural influences can also impact the final appearance of the glazed pottery pieces.
