A friend several years back created a very nice cone non -glossy black
glaze based on Alberta slip. My recollection is he started with a regular
cone 10 clear made with feldspar, whiting, silica, clay, and a touch of
zinc (which if left out makes no difference in appearance or clarity) and
did a line blend with the Alberta slip. He used Alberta's slip because
Albany was not available.
From another approach, I make a nice non-gloss black with addition of 15 %
wt red iron oxide to my standard shino glaze at cone 10 reduction. It does
tend to move where thick (two dips). Fifteen percent was chosen because
15% is the nominal loading of RIO added to our studio clear for our glossy
Cola Black glaze.
Do you need the recipes?
