Glazes are a special type of coating applied to pottery and ceramics to give them a shiny finish and vibrant colors. They are made from a mixture of minerals, water, and sometimes colorants, which are applied to the surface of the clay before it is fired in a kiln. When heated, the glaze melts and forms a smooth, glass-like surface that enhances the beauty of the piece and makes it more durable. In addition to aesthetics, glazes can also serve practical purposes. For example, they can make pottery waterproof, allowing it to hold liquids without leaking. Different types of glazes, such as matte, glossy, or transparent, can create various effects, making each piece unique and adding to the artistry of ceramics.
