I was thinking maybe Silicon Carbide in 420 mesh would be useful in kiln
wash. I wonder though, if it would be too conductive to use in an electric
kiln. Any thoughts?

To the best of my knowledge, finely divided Silicon Carbide decomposes =

Finely divided Silicon carbide reacts readily in contact with molten =

There may be other, better informed, opinions.
