cone 9-10 tile setters and thermocouple flaking

Hi!

I have been firing tiles to cone 9. I actually bought a larger kiln so that
I could fire more tiles at once, and keep them away from the elements. The
problem that I am now having is that I can only fit about 21 - 6.5"
tiles/load in my ConeArt 2823 if I take into account that they must be well
away from from the flaking thermocouples, not spanning the positions where
the half shelves come together, and not firing anything in that section of
the kiln that does not have elements (about 2/3 of the way to the top). They
are flat and unwarped, but it seems like a waste of time energy to only be
able to fire such a small number. In order to fire more tiles at one time, I
would like to use tile setters rather than shelves. Because I am firing to
cone 9, I need the setters that would be like miniture shelves with feet at
the edges, so that the tiles are fully supported to prevent warping,and they
must be rated for cone 10... something like plate setters, only square. Does
anyone know where I can get these type of setters?

By the way, is it common for thermocouples to flake? This happens at both
cone 04 and cone 9. I welcome all suggestions.

Thanks in advance for the info.

My best,
Paulette Carr

RE the tile setters: I know Seattle Pottery Supply (you'd think I work
for them! I don't) has these, and you could probably mail-order them:
www.seattlepotterysupply.com. I'm sure you could find a vendor on the
web, too, perhaps close to where you live.

Hi, Paulette.
I have gotten these from AMACO in he past. I hope they still have them,
because I'm going to need to replace some soon.

You can also make your own setters for a lot less money. I had to make 60 -
8" tile setters for a mural project with the city. I bought the clay 2272
from Laguna which is their refractory clay. I bought the clay dry but I
would think you could get it wet. These setters have weathered their
firings very well.
