The February issue of Ceramic's Monthly has a nice article (page 45) on
a glaze combination that simulates a wood-fired look in an electric kiln
by Richard Busch. The pictures are beautiful, so I tried it. (I won't
post the recipe - check the magazine.)
The results were really nice. It's a nice red-brown color and feels
really good. The best part is that it brushes on really well. For
those of you who like to brush on your glazes, this Nutmeg is a good
one.
I tried the same Nutmeg base and changed the colorants to 1% RIO, 1/2%
cobalt carb, 4% tin and .25% ilminite, and got a really nice muted light
blue with tiny speckles, which also brushed on like a dream. No brush
strokes or anything and a smooth buttery feel.
I have only used this on decorative stuff (since I don't know about the
food-safe aspect of the glaze). Maybe some of the glaze gurus out there
could give us some thoughts on this.
Also, the article has the recipe for the black stain he uses, but it is
chocked full of nasty stuff (manganese, nickel, black copper oxide).
Does anybody have suggestions for a "healthier" black stain?

Sylvia,
I picked up a tip from another Clayarter, Bonnie Hellman (sp?). Use a clear
glaze and add a prepared stain, like Mason's Black 6600. Try increments of
5% to 10%.
I use Tony Hansen's 5 X 20 clear glaze at 5% Black Mason.

Hello Sylvia
After the massive use of Manganese - not knowing it's danger I got this advise from
Ron Roy, to use 8-9 black iron oxide and 1-2 cobalt oxide. It was for imprints but I use
it for engob too.
This is not the point: Sometimes you use manganese, when it is needed.
The way I see it , I use manganese as less as possible, The last time I bought this
material was probably 3 years ago, but when it is a must I use it. You want to make
wood fire in electric kiln?
I see it as a decorative glaze!
