Frequently Asked Questions

Q: What is the difference between washed and calcined kaolin clay?

Washed kaolin is purified through water to remove impurities, while calcined kaolin is heated to high temperatures to remove chemically bound water, resulting in higher stability, whiteness, and fire resistance.

Q: How does 325 mesh calcined kaolin improve paint quality?

It acts as a high-efficiency filler and extender, improving opacity, preventing sagging, and enhancing the overall texture and durability of the paint film.

Q: Why is Kaolin Clay essential for high-end ceramics?

Due to its high plasticity and ability to withstand extreme temperatures, it allows for the creation of strong, crack-resistant porcelain and sanitaryware with a refined finish.

Q: What factors influence the bulk price of Kaolin clay?

Pricing is primarily driven by the purity of the source, the processing method (e.g., calcination temperature), particle size requirements (mesh), and the total volume of the order.

Q: Can this material be used in the cosmetics industry?

Yes, Kaolin is a natural mineral widely used in cosmetics for its high oil and water absorption and its ability to adjust brightness for a natural skin-tone appearance.

Q: What packaging options are available for industrial shipments?

We offer standard 25kg PP or paper bags for small-to-medium orders and 500kg to 1000kg jumbo bags for large-scale industrial bulk shipments, with customization available.
