Quartz inversion doesn't result in explosions -my experience has been that =
pots, usually larger plates, crack into 2 or more parts. Way back I had a a=
bowl glazed and fired to cone 10 sit outside through a rain or two. On ref=
ire the bowl lft shards all over the kiln -and in most of the other pots. S=
ounds very much like the event Vince Pitelka posted. i attribute the explos=
ion to H2O in the clay...-Rimas
