Water-washed kaolin sits at 2 on the Mohs hardness scale, just above pure talc. Water-washing removes most of the free silica (sand) that occurs as an impurity in kaolin deposits. However, a kaolin that has simply been mined and milled would have sand milled into it and be much more abrasive.

Calcium and magnesium are the hard water minerals resulting in scaling problems and failures in pipelines of boilers and heat transfer equipment (Siger & Bergaut 1995).
On the other hand if the kaolin is transported by running water and deposited elsewhere, one has a secondary deposit.

These deposits are exploited primarily for ceramic …
