Hi Sean,
Yes, they are a good idea. They save a lot of space. The ones I have are
flat discs with small extensions, for detachable feet,
giving you options of how high you want the space between to be. I usuall=
y
just go three plates high, but I can get six plates per shelf.
Two stacks per shelf. The shelf is 12 x 24. I think. Or thereabouts.
Advancers tend to be a bit skimpy.
I have had my setters for several years now, no warpage yet, but you have t=
o
be careful with them.
I use alumina in my wax and am careful to clean the plate bottoms. I don't
use kiln wash.
Hope this helps.

Subject: plate setters... good idea?
Hi All,
Does anyone use plate setters?
Considering a set from Bailey to save kiln space..........but I know
no one who actually uses such equipment.
Your knowledge on this would be appreciated.
Thanks,
Sean

I have not used plate setters, though I expect they would be good to use.
I have two Paragons that are 24 inches and will accept 22 inch shelves.
I fire my plates on them. The plates are large, 14 inches, and I fire a
single plate on each shelf. By the time I get them stacked, with a two
inch post between, the internal mass is considerable. This requires a
very slow firing up and cooling down so the heat distribution remains
fairly constant. I learned the hard way that with this load I should
NEVER EVER raise the lid for a peek. I succeeded in breaking every plate
in a full load once - and I won't repeat that mistake. Each plate
cracked in half - straight through the middle.
I fire my plates on clean circular shelves with no kiln wash. I do,
however, spread a very thin layer of alumina hydrate on each shelf
before placing a plate on a shelf. This permits movement during firing
and eliminates the possibility of a plate hanging up during shrinkage
and cracking. The alumina hydrate act like little tiny ball bearings and
allows the clay to move. All my plates have a foot ring and are glazed
inside the ring, so I am very careful about where the glaze line is, so
that no alumina gets into the glaze during the process of firing.
I turn my shelves over after each firing to avoid the warping that seems
to always eventually happen over time, if steps aren't taken.
This is my way - works for me.
