Overglazing is a ceramic technique where a transparent or semi-transparent glaze is applied over a previously glazed surface. This process enhances the visual appeal of the piece, adding depth and richness to the colors. It can also provide a protective layer, making the pottery more durable. This technique is often used in pottery and ceramics to achieve specific artistic effects. Artists may choose to overglaze to create unique finishes or to highlight certain features of their work. Common materials used in overglazing include ceramic glazes and underglazes, which can produce various textures and colors.
