Porcelain

Acts as a framework for the fired material, increasing mechanical strength and resistance to thermal shock.

Porcelain is a highly refined ceramic material primarily composed of , feldspar , and quartz . It is valued for its unique combination of strength, delicate translucency, and pure white color, often being referred to as "the noblest form of ceramics". Key Raw Materials

Generally contains 25% kaolin, 45% quartz, and 30% feldspar, firing at lower temperatures. Porcelain

Acts as a "flux," melting during firing to create a glassy matrix that bonds the other ingredients together, making the final piece non-porous (vitrified).

Typically 50% kaolin, 25% quartz, and 25% feldspar. Acts as a framework for the fired material,

Often reinforced with alumina or ball clay for extreme durability in commercial use.

Specifically added to Bone China recipes (up to 50%) to allow for thinner, lighter, and more translucent pieces. Common Formulations Key Raw Materials Generally contains 25% kaolin, 45%

Higher feldspar content (70–85%) mixed with quartz and a small amount of kaolin for aesthetic translucency.
