Clayarters:
I recently got about 100 lbs of someone's old green clay tennis court.
It was being resurfaced so I decided to grab some and see how much
'clay' it contained.
After slaking I notice there is a claylike substance, but it is
minimal in %age . . about 90% seems to be larger particles (up to
large grit size) made of some already fired green substance (or a
shale) . . .
Anyway the finer stuff is certainly fine, and seductive. Any advice
about usage? Crafting into a glaze, an overglaze for painting?
