pie plates and ovenware

I would be interested in hearing whether or not pie plates are a good
item to be making and selling. I was thinking to make pie plates and
sell them with a pie for a fundraising event, but have this "feeling"
about them too. They are wide, flat and probably more stressed in the
making as well as being put into very hot ovens. Admittedly mine might
not be used for pie after the first one. They aren't classic and look
more like a low baking dish. Any other thoughts about these forms?

Hi Autum,

You don't say what temperature you are firing at - if high fire
stoneware make sure there is no cristobalite produced during the
firing in the body you will use. cristobalite goes through it volume
changes at cooking temperatures.

Glaze fit is important - I can help with that!

Hi Autumn,

Let me check out the expansion of that glaze - just to make sure it's
not a low expansion glaze. I do have some dilatometer charts (old) of
plainsman clays so tell me which one it is.

Very rare to have a cristobalite problem at cone 6 by the way.

The shape of the plate where it goes from flat up to the sides should
be as rounded as possible to help transfer any stresses more evenly.

The second firing cracking may be happening on the way up in the
second firing - if the edge of the glaze where it's cracked is rounded
(melted a bit) then that is when the crack happened - if it's sharp
it happened on the way down. Probably well above oven temperatures.

No harm in making some and testing them in your oven to see if they
will work OK.

Hi Ben,

I used to think cristobalite would not be a problem at cone 6 but -
while exploring a problem a potter was having with cracking casseroles
- after checking the expansion of her glaze - it because obvious that
something else had to be wrong.

She sent me some fired clay samples and there was some cristobalite
present - she changed clay suppliers and the problem stopped.

To this day I have not been able to find out why that clay supplier
was getting cristobalite in some of their cone 6 bodies - I suspect it
was coming in with one of their raw materials and was not being
produced during her firings.

I offered to help find the problem but was not taken up on the offer.
