I wonder if any of you have had a problem with using alumina hydrate in kiln
wash in an electric kiln. A friend of mine is convinced that the a-h she
used in wax resist as well as kiln wash on the shelves destroyed the
elements. When they needed to be replaced they came out in tiny pieces
instead of in one long coil. It took hours of pulling out all the fragments
with needle-nosed pliers. She says she remembers reading on Clayart a while
back that alumina hydrate gave problems in an electric kiln. Can any of you
enlighten me here?? I have just had my shelves sanded and am looking for a
good dependable wash recipe. TIA!

When I changed the elements in my electric kiln (after years of intensive
firings) I was warned that the old ones would come out in pieces. They get
brittle after long periods of use. I'm pretty ignorant from a chemical
standpoint but I don't think the alumina hydrate was the problem. I was
warned that particles on an element (pieces from an unfortunate pot
explosion for example)can shorten the life of the elements considerably.

Instead of kiln wash one can use grog. Sprinkle it on each shelf as you are
loading (carefully to not get it on the pieces below, perhaps the 1st time do it
in a bisque load) and after the firing it is sufficiently stuck in place on the
shelf that it won't crumble off. You only need to add more is something
sticks. If a pot sticks, it comes off with grog on it. When you load each
time, simply brush off the underside of the shelf so no grog falls on the pots
below. I just got a new kiln and I will use this method. I have worked in
studios that used either method (wash or grog) and I prefer the grog.

Even better is fine Molochite, some grogs have an iron content which can
be a problem a high temperatures.
