hi,
im a potter out here in calif.... i picked up your address from an article
on slip stuff
im looking for recomendations for grogs to be mixed with earthen ware clay
(06 or less) to help withstand open pit firing ...
but will not mess up the ability to burnish the clay to that lovely
sheen-polish .
anyway...
hope this message makes its way thru the telephone lines or where ever it
goes.
thanks!
Michael

Hi,
You could add up to 50% grog of different sizes to help withstand the shock
of pit firing. 25% works well. I think the burnishing will push the grog
back in below the surface so you will still get a smooth surface.

On this subject, I have added coffee grounds and tea leaves (from bags) to
clay to open it up and lighten it up, and it works fine, both as a grog to
help in building, and to lighten the piece. Has anyone tried this to help
with heat shock resistance? If so, I bet you could burnish over these, since
they are soft, especially the tea leaves.

This reminds me of an article I read some time ago
about adding vermiculite.. And the vermiculite adds
little golden flecks too..But make sure those suckers
are dry!!!
