Where does one get shale or what would a decent sub be?

Yo Lee,

I get mine on a road cut in Johnson City TN, but you could just use redart.

Old post I've just caught up on... Shales are fascinating in their variation, mostly being similar to clay in composition but having different oxides present indicated by their colour. I've tries a yellow shale as a glaze additive changing the base glaze from a glossy translucent to a stiffish opaque pale green in reduction (+10% shale). Another shale, grey this time, produced a chun when I substituted it for the kaolin, iron & manganese oxides in a translucent mid-green glaze. I've also seen red and purplish shales (manganese bearing perhaps?), white shale and shales with visible hematite crystals imbedded, all of which would be wonderful fun to experiment with when I can find the time.
