Glazing techniques in ceramics serve distinct purposes depending on whether the piece is functional porcelain or a decorative sculpture. Functional porcelain, such as tableware or vases, prioritizes durability and food safety. Glazes here are often matte or glossy, formulated to withstand daily use, resist chipping, and prevent leaching of harmful materials. Common techniques include dipping, spraying, or brushing, with finishes like celadon or underglaze patterns enhancing aesthetics without compromising utility.

In contrast, decorative sculptures embrace experimental and artistic glazing methods. Artists may layer multiple glazes, use crackle effects, or incorporate metallic lusters to create visual depth and texture. Techniques like raku or pit firing produce unpredictable, vibrant results, prioritizing artistic expression over practicality. The glaze application can be uneven or intentionally flawed to evoke organic, rustic charm.

While functional pieces rely on standardized, tested glazes, sculptures often break conventions, blending glazes with mixed media or unconventional firing processes. Both forms, however, share the transformative magic of glaze—turning clay into timeless art or everyday objects of beauty.
