Dear Xavier

 

The best product I have seen used with ordinary clay is sodium silicate.
There are two forms of it available, one is a liquid. Use that one if you
can get it.

 

It makes the clay very hard and resistant to thermal shock.

Crispin

  Potasium salt !  

Potasium chloride salt cement is used with quartsite to make mais mill
stones .

Strong it must be .
