Underglaze is a coloured decorating medium applied to pottery before a clear glaze, allowing detailed painting, patterns, and designs that remain protected and durable once fired.
Underglaze is typically applied before a clear glaze and used for decoration and detail, while glaze is often used on its own as a glassy, protective coating over the whole piece.
Underglaze can generally be applied to both greenware and bisque-fired pottery, though bisque ware is more commonly used as it's easier to handle and produces more predictable colour results.
Yes, in most cases a clear glaze is applied over underglaze to seal the surface, make it food-safe and waterproof, and add durability and shine.
Yes, some underglaze colours can shift slightly depending on firing temperature, especially above 1080°C, so it's recommended to test colours under your specific firing conditions.
Underglaze can be applied by brush, sponge, or dipping, similar to painting, allowing for fine detail work, solid colour blocks, or layered decorative techniques.
