Typically 50% kaolin, 25% quartz, and 25% feldspar.
Specifically added to Bone China recipes (up to 50%) to allow for thinner, lighter, and more translucent pieces. Common Formulations
Higher feldspar content (70–85%) mixed with quartz and a small amount of kaolin for aesthetic translucency. Porcelain
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. Typically 50% kaolin, 25% quartz, and 25% feldspar
Proportions vary based on the intended use and firing temperature:
Often reinforced with alumina or ball clay for extreme durability in commercial use. Porcelain is a highly refined ceramic material primarily
Acts as a framework for the fired material, increasing mechanical strength and resistance to thermal shock.
