Thanks. I will get some WSO but also will try a little Red Calico with
sand to see what it does.

lake with friend
Barbara, some clays are much better at surviving the thermal shock
of
raku than others, though as your friend says just about any clay will
work.
THe difference will be the survival rate of the pots.
I currently use Black Jack clay and Laguna's WSO. I used to my own
mix
which was a 100 lb bag of Hawthorn Bond, a 50 lb bag of ball clay, a 50
lb
bag of Gold Art and grog to taste. The grog content will range from less
than 10 to 20%. I mixed the body in a Soldner Mixer and de-aired it in a
Venco de-airing pugmill.
Any ready made clay with a resonable amount of grog or kyanite will
do.
Just tell your clay supplier what you are attempting. If you want to use
the
clay that you have on hand just wedge some sand and/or grog into it. It
will
probably work just fine.
