So John, when are you adding a cone 6 (Reduction, Oxidation & salt fire) to your class schedule???? June could be a guest speaker. Oh,Happy Gregorian New Year.
Working on it!

And a book, as well!!!
Is there something missing or should the formula add to 90?
June tells me that someone may have left out the ball clay to make it less refractory. She thinks she got it from the cone 6 google group :
