I was a bit disappointed with this particular test, I have seen Teadust in pictures and it is basically a gloss black with specks of yellow brown here and there, very nice but my test resulted in what really reminds me of a cone 10 glaze, Reitz Green, only without the green cast.
This was fired on cone 6 porcelain, on both a square extruded cylinder and a small vase. It has a waxy mat surface with no glaze faults except a little pinholing. The color is a deep tone, hard to describe but the red iron oxide and manganese combine to create a dense opaque surface. However no black or nice specks here or there, very much like Reitz green as i said. Thickness also seemed to make little difference, same surface.
Does anyone else have experience with Teadust?

Hi Tracy,
Manganese is not the right oxide - try Magnesium - it certainly works in a
tenmoku glaze to get the tea dust effect - talc should work just fine.
