Avril:
Don't put your self in the position of saying for certain that man made
stones will not fracture during a firing. I have used them in lost wax
successfully, however the temperature was not over 1200 to 1300 degrees F.
Rate of increase and decrease are very important factors. Slow rate of
increase and decrease in temperature is mandatory.
Good luck.
Bob
