Back in August, Veronica Shelford posted the following formula for "V's
Tenmoku Gold" (cone 6 ox) to Clayart:
61 Cornwall Stone
8 Whiting
3 Gerstley Borate
10 Red Iron Oxide
5.5 Lithium Carb
7 Dolomite
5.5 Flint
She described it as her own variation on the Richmond (BC) Potters' Club "Red
Tenmoku" and having gold flecks on a red-brown base. I tried it on a warm
brown clay body and really like the results. For me, at ^6, it is a very
deep, glossy chocolate brown with gold flecks. Because of unintentional
uneven temps in subsequent firings, I have found that at ^5 the glaze is
rich, glossy brown with more dense patches of a more matt gold "haze," and at
^7 the gold disappears and the result was glossy dark brown with breaks of
medium tan on high spots. The ^5 and ^7 results were obtained after adding
5% flint to the original formula to try to correct some flowing and crazing.
Just thought this might be of some interest to those experimenting with
Tenmoku glazes in oxidation.
