Clay

Product Benefits

The properties of ball clays are down to their relatively high content of colloidal and organic matter.

Ball clays will provide :

  • Rheological stability
  • Unfired strength
  • Plasticity
  • Workability
  • Higher bending strength on both green and dried stage
  • White-fired colour
  • Low level of organic matter that allows fast firing cycle
  • High fusibility features, that can reduce the final porosity of ceramic body and increase the speed of the firing cycle with natural gas saving and more production yield
