  Ball clay is a type of clay with high plasticity, rich in organic matter. Mainly
  consisting of unprocessed kaolin,mineral such as quartz,glimmer are accompanied
  and grown. The content of the organic matter is up to 15%. Main chemical
  composition is SiO2, Al2O3, H2O, C,and H2.A small amount of Fe2O3, TiO2,
  Na2O, K2O. The colour is varied, depending mainly on the content of black,
  gray. After firing, it is white, yellow or reddish brown.It differs dependingon
  the impurity content.The quality is soft, the viscidity is great and it is an important

  combination clay in the ceramic industry.

  Packing：25kg P.P.Bag
