👉 Porcelain fluid, also known as porcelain slip or kaolin-based slip, is a fine, translucent, and highly absorbent material primarily composed of kaolin clay, often mixed with other additives like feldspar and quartz. This substance is crucial in the ceramic process, particularly in the creation of porcelain, as it serves as a slip—a liquid or semi-liquid mixture applied to the surface of the clay body before firing. When porcelain fluid is applied, it helps to smooth out surface irregularities, enhance the slip's adhesion to the clay, and create a uniform, slip-cast surface. This process is fundamental for achieving the delicate, glossy finish characteristic of porcelain, as it allows for precise shaping and detailed decoration before the final firing.
