Though it has become a generic term used for all formal dinnerware, porcelain is actually a hard, translucent clayware body usually comprised of 50 percent kaolin, 25 percent feldspar and 25 percent quartz.
Kaolin gives the body a bright white color and is the base for plasticity, durability, and consistency. Quartz keeps porcelain stable and feldspar makes it hard and glossy like glass through a process called vitrification. A decorative glaze is fused to the clay body at a temperature of 2700 to 2800 degrees Fahrenheit.
Porcelain is impervious to bacterial growth. Ideal for all uses at the table and in the kitchen, porcelain is dishwasher, oven, and microwave safe.
