Alisa and Claus Clausen on sun 6 aug 00
Tested on a light grey mid range stoneware, fired to cone 6, oxidation.
54.5 Kona F4 feldpar
2.5 Manganese Dioxide
I substituted Kona F4 spar with my local Forshammer spar. I rounded the =
amounts up to the nearest whole decimal.
Results were a deep iron brown glossy glaze with some speckling. This =
glaze in oxidation resembles Chris Wolff's Plum. It could be a good =
substitute for that glaze when the G.B. runs out. It has a nice surface =
with some play in the color, due to the lighter spots. Where it was =
thickest over the rim of the test cup, it had a rougher surface with =
very slight craters.
No dripping or running.
