Hi Everyone,
I'm considering not kiln washing my new nitride bonded silicon
carbide shelves. I'd love to be able to flip the shelves periodically.
But my sneaking suspicion is that even if my glazes are well behaved,
my clay body might stick to the shelf and crack off little pieces of
pots.....any thoughts ?
TIA

If you use hot wax on the bottoms of your pots you could just sit your pots on
a thin layer of sand just before you load them on the shelves. Care should be
taken not to scrape the sand off while loading and ending up with sand in a
bowl below it.

Does this mean just regular, run of the mill sand? We have
a pile beside the house waiting to be bagged up. Will this
survive to ^10? I've been looking for a better way than kiln
wash as the new clay I've chosen to use tends to attach itself
to the kiln shelf (and I mean the clay - I wax carefully, and
my chosen glazes do not run).
TIA!

Jennifer,
I spread a little silver sand on my shelves. This will brush off when
you want to turn over your shelves.

We use Alumina Hydrate or fine molochite on our shelves at work, comb it
flat with an old hacksaw blade and wipe the edges. It tips off onto a
newspaper after the firing and is re-used. Means you can flip your
shelves without problems.

We also use alumina hydrate, and while it won't protect against major
drips,it seems to prevent the clay body from sticking to the shelves. It
does mean a lot of dust on the bottoms of pots,however, and we wonder about
breathing it. (I wear a mask. When I remember to...) I also dip my bisque
cones that go in the electric cone sitter in alumina hydrate for a
dusting,to prevent them from sticking.

I have been using a mixture of 1/2 aluminum hydrate and 1/2 EPK for
years and it works for me. I put on a thin wash and can flip the
shelves with no trouble. I use both silicon carbide and mullite but
don't flip the former. I have the mullite shelves marked so I flip them
four ways. If I have a new glaze I am not certain about, I put some
placing sand under it. Seems to work.

Tracy, Years ago I used desert sand as a cheap substitute for grog & ended up
with a pebbly glassy, pop out problem. Interesting on sculptural works, awful
on functional pieces. What kind of sand are you using?

Jennifer,
One word of caution concerning nitride bonded silicon carbide; frequent
movement may cause cracking. Clay bonded silcon carbide can handle regular
loading and unloading, but nitride bonded seems a little fussier. Some folks
have this problem....some don't. I guess it's the phase of the moon when
they're made or something. If you start getting cracks, try to leave as many
shelves as possible in place. If you don't get any cracks, flip away.

By product from the feldspar and silica mining which goes on there in Mitchal
county NC. They give it away by the dump loads or use it for land fills. I
would always test the sand you get before using it in a whole kiln load of
pots. Do one pot next time you fire your kiln. Play sand sold at hardware
stores by the bag full should also work.
Good luck Tracy

Jennifer...
I suspect that you have New Castle Refractory's SiC Nitrided bonded
shelves which we also use. I use the Lee's Kiln wash from Axner's. I only
coat one side of the shelf with the Lee's and obviously don't flip the
shelves. We have had great result with the shelves and have had no
problems over the past couple of years with the shelves cracking... If you
do get glaze drips on an uncoated shelf then you are going to have "hell to
pay" in trying to remove the molten glaze... ...Marshall

Most sand is silica.....Mucho high fire until it melts about 3000 deg....put a
little in a dish and fire it in your next fire. Should work ok. Or try it
on the foot of a small pot first.
