In 1984 I used a clay that Paul Soldnre had used for whatever he was
doing at the time, one of several clays. low salt mostly.
What I found interesting was that at a cone 9/10, salt firing this clay
seemed to repel the salt, it really did not achieve any type of glazed
surface at all.
I still have a few bowls that I had made. The clay was:
equal parts: fireclay, ball clay, kaolin, talc and sand.
I felt it was the talc that resisted the salt glazing.
I wondered how this may factor in any way of treating the inside of a
salt kiln?
Talc?
Just a thought,
Maggie
