Hey ya'll, one more query. I'm looking for a nice black tenmoku that has a
nice fluidity to it. I used to make one with a local slip and wood ash, but
the slip is proving to be more and more unreliable. It looked great running
into other glazes, similar to Richard Batterhams work. I'd prefer one using
wood ash, if anyone can give me a starting point it would be sooooo helpful.
Thanks in advance!

Brandon,
In "A Potter's Book," Bernard Leach lists using 62 to 68% of a 4-3-2-1
base plus about 10% red iron oxide, 12.5% silica, 9.5 to 17% ash. The base
is 40 feldspar, 30 quartz, 20 limestone, 10 kaolin.
Use with care! The base glaze is very stable up to cone 10. However,
even at the low end of the iron and ash addition the glaze becomes low in
alumina and silica and will want to run. Leach called it a cone 8 to 10
glaze.
Hope this gives you a starting point for testing!

wondering if that's excuse enough to head for the studio instead of the
orchard where the fruit trees are begging to be pruned....

If I'm well informed Batterham's glaze called by you 'fluid tenmoku' could
be a glaze with manganese. I don't think you can keep your tenmoku black on
top of another ash or ironglaze. But if somebody has succeeded I would also
like to hear about it.

PS I'll be without Clayart-email for the next two months, so if somebody
has an answer about this fluid tenmoku, could he or she send a copy of the
answer to my private email address.
