What is the primary use of ribbon or loop tools in ceramics?

Ribbon or loop tools are essential implements used primarily in ceramics for carving, trimming, and hollowing out shapes in clay. They feature a curved, looped cutting edge, which allows artists to create intricate details and refine the surface of their work. This capability makes them especially valuable during the hand-building stage, where precision is necessary to achieve the desired form and surface texture.

These tools facilitate the removal of excess clay and the smoothing of surfaces, contributing to the overall craftsmanship of ceramic pieces. Artists employ them to add depth, refine edges, and enhance decorative elements on their pottery. Their versatility is especially advantageous when working with larger or more complex forms, as they can reach into areas that other tools might not easily access.

In contrast to the other options, measuring the thickness of clay involves different types of tools, while molding clay is more typically associated with hands or shaping tools rather than ribbon tools. Applying glaze is generally accomplished with brushes, sponges, or sprayers specifically designed for glazing rather than using carving tools. Thus, option B accurately highlights the primary function of ribbon or loop tools in the ceramics process.
