China Clay, also known as kaolin, is a naturally occurring, soft, whitish clay substance. It's a hydrated aluminum silicate crystalline mineral that's formed over millions of years by the hydrothermal decomposition of granite rocks.
China Clay is known for its creamy-white color and smooth surface. These characteristics, coupled with its fine particle size, make it a popular choice in industries that require refined materials. Kaolin exhibits exceptional heat resistance, making it suitable for applications involving exposure to high temperatures.
In the realm of ceramics, China Clay plays a pivotal role. Its remarkable ability to remain stable at high temperatures makes it an indispensable ingredient in producing porcelain, earthenware, and other ceramics. Often associated with luxury and refinement, porcelain owes its elegance to China Clay. The clay’s purity and plasticity allow artisans to shape intricate designs, and its white color acts as a pristine canvas for decorative glazes.
