Question---I heard that Ajax is a suitable subsitiute for calinated kaolin.
Is this true? And at what ratio ?

You mean "Ajax, the foaming cleanser, wash the dirt right down the drain"
(old singing commercial)? That Ajax? As far as I know it contains
chlorine and you really don't want that stuff in the air. I have heard that
these scouring powders contain either silica or spar as their "gritty"
ingredient, but why not put a bowl of kaolin in your bisque kiln and get it
over with?

Lyn - Do you mean "calcined" kaolin? That, in simple terms, means the
chemically combined water has been removed. You can do this by firing
the kaolin in a bisqued bowl, in your next bisque firing.
