Kurt,
I do not know the answer, but pyroceram - Corning ware,which is
specifically made for use in the microwave, gets hot enough that the only
way to handle it is with a kitchen towl. Mia in ABQ

Been searching the archives and can't find an answer. Seems to me that at
one time it was posted (on Clayart) that if a stoneware piece feels hot
after heating it in a microwave (with food on it), that is an indication of
something? My question - indication of what about the stoneware piece?

dear kurt, and clayarters,
it could be from water soaking into the clay & steam
forming. or even the glaze being made with a metal
oxide. i am not an expert ~ just spent the night at a
holiday inn express. :-) best regard, lynn

Hi Kurt,
I heard this as well. My memory of it is that if the stoneware is hot
WITHOUT food in it, then the piece is porous and has retained enough
moisture to be heated by the microwave. If it does have food in it and gets
hot then it may be conducting the heat from the food, in which case some
might think it too thin. Microwaves generally don't work on dry objects.
Regards,
Jim

Hi Kurt,
Well it could be that the hot food has heated the pot, but I think what you
are referring to is that it is an indication that the clay is not very well
vitrified. Microwaves are best at heating water and any clay that absorbs
more than 2-3 % moisture will heat up in a microwave. That is why
earthenware is not satisfactory in a microwave unless it is completely
encased in an excellent glaze (which it almost never is).
Regards,
John
