Ron, can you step in and give Compressive Modulus for Axner's Mary's ^6 Porcelain ?? I assume there is probably a range, depending on moisture content.
Is this one of the measurements that you take when standardizing clay bodies?
Regards,
Jim

Dear Jim Kasper,
Sorry but Axner clays are not, as far as I know, imported "down Under"
From the crude measurements I have been able to get via an "Indentation" =
test using a square 45=B0 pyramid the porcelain clay I use seems to give =
a value less than 1 Kg. per Sq. Cm.
But this will decrease when you start throwing due to adsorbtion of more =
water and the effect of thixotropy.
Interesting to think about.
Best regards.
Ivor.
