Proportions vary based on the intended use and firing temperature:
Generally contains 25% kaolin, 45% quartz, and 30% feldspar, firing at lower temperatures. Porcelain
The foundational ingredient. It provides structural integrity and maintains the white color at high temperatures. Proportions vary based on the intended use and
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). and 30% feldspar
Specifically added to Bone China recipes (up to 50%) to allow for thinner, lighter, and more translucent pieces. Common Formulations
Often reinforced with alumina or ball clay for extreme durability in commercial use.
The specific "recipe" or content for porcelain determines its final properties like whiteness, strength, and translucency.
