Product Benefits

Sibelco extracts high-quality kaolins which are partly refined in a kaolin preparation unit and sold as refined kaolin noodles. Due to the kaolinitic structure of our kaolins, they can improve the firing process and yield at all. Furthermore the kaolin as a powder can easy be solve in water to create specific colour effects on the surface, especially for bricks.

Kaolins are characterized by:

  • Good firing process
  • Coloring effects in the body and on the product surface
