Hello Everybody,
Good black can be obtained with cobalt contacting stain. I wonder if good
black can be obtained with cobalt free black (like Cr-Fe / Cr-Fe-Ni) ? Want
to use at 1020 degree centigrade in Zinc less frit. Somewhat brownish warm
tint is O.K..
Any good recipe ? Can any one suggest good book for it ?
Thanks in advance,
Mehul

In a recient test I tried an overlap with some very interesting results:
a Temnoku over an ash-based Chun. On the overlap the glaze was shiny and
very black. I have not made further tests. Perhaps this may be a
starting point.

Got this out of a CM review book many many moons ago. No
credit given in book. At ^9 is deep chocolate - at hard 10
is almost black
Ox Temoku ^9-10
46.7 Cornwall Stone (mine is blue)
11.1 EPK
20.2 Silica
14.5 Whiting
7.5 Red Iron Oxide
I use 1.5-2% macaloid as a suspender - or it goes brick-hard.
Apply thickly - doesn't run. If thin, then brownish. Breaks
nicely over *sharp* edges.
