Glazing in ceramics refers to the process of applying a liquid glass coating to the surface of a ceramic object before firing it. Glazes serve multiple purposes, including enhancing the aesthetic appeal of the piece, creating a smooth and durable surface, and providing a protective layer against moisture, stains, and chemical reactions. Glazes can be transparent, translucent, or opaque, and they come in a wide range of colors and finishes, allowing artists and potters to add depth, texture, and visual interest to their creations.
