You can place the elements on a shelf in the kiln and fire to red heat
(1200F) for the purpose of burning off oil used during the manufacturing
process. This will not make the elements brittle.
Mix ITC with water, thin mix, pour in dry wall tray (cheap plastic), drag
elements though the mix, applying a very thin coating. Do not coat the pig
tails.
Allow to dry, install.
First firing may cause some black flaking during the cooling cycle.

I want to try out various electric kiln reduction techniques.
Coincidentally, my elements are due for replacement. At least the top
two definitely are. I would like to treat the new elements with ITC, but
the advice as to how exactly is conflicting at best.
Some recommend firing the new elements for a few minutes, then treating
them. But that makes them fragile, doesn't it? So how can I fire them,
then take out? They will probably fall apart. Besides, I'd rather not
remove and replace elements an extra turn, because the brick groves are
pretty fragile.
I could potentially coil the new ones and put them on a shelf and fire
with the old ones, but again, wont the new ones become fragile? Will I
be able to put them in without destroying?
Next comes the application. Dipping, painting or spraying? I would think
dipping should produce the most even coat.
People who have done this, please speak up!
Any advice greatly appreciated!
Dennis
