Hi Karin,
Something fishy here - it already totals 100.03 but there is no Fe2O3 which
must be there for a tenmoku.
My tenmoku has 7.69% iron for instance.

A lot of glaze formulas will not count the oxides in the 100% total of =
the base glaze. This may have been one of them. It does make a major =
difference especially with fluxes like iron in the tenmoku glazes. Like =
Ron said, just run some tests.=20
