What is the receipt for porcelain eggshell?

Porcelain eggshell refers to a type of porcelain that is extremely thin and delicate, often characterized by its translucent quality. To create porcelain eggshell, a mixture of kaolin clay, feldspar, and quartz is used, which is then shaped and fired at high temperatures. The firing process renders the material strong yet lightweight, allowing it to achieve its signature thinness. It's often used in fine china and decorative pieces due to its elegant appearance.
