What is the fine white day used to make porcelain?

The fine white clay used to make porcelain is called kaolin. It is a key ingredient in porcelain production, providing the necessary plasticity and strength when fired. Kaolin is valued for its purity and ability to withstand high temperatures, giving porcelain its characteristic translucence and durability. This clay is typically found in deposits formed by the weathering of feldspar-rich rocks.
