The specific "recipe" or content for porcelain determines its final properties like whiteness, strength, and translucency.
The foundational ingredient. It provides structural integrity and maintains the white color at high temperatures. Porcelain
Generally contains 25% kaolin, 45% quartz, and 30% feldspar, firing at lower temperatures. The specific "recipe" or content for porcelain determines
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
Typically 50% kaolin, 25% quartz, and 25% feldspar.
Higher feldspar content (70–85%) mixed with quartz and a small amount of kaolin for aesthetic translucency.
Acts as a framework for the fired material, increasing mechanical strength and resistance to thermal shock.
