Hi Fellow Clayarters.
I have a potter friend, who is not as yet on Clayart, but who hopes
to be soon. In the meantime, he is looking the recipe for a green glaze,
and I wondered if anyone on Clayart knew of this glaze, had the recipe, or
had the recipe for something very similar. It is called Bower's Green and
was used by a pottery at the turn of the century, which has since closed
down. It is a matt greenish blue or bluish green. He thinks it might have
been cone 6 but is not at all sure of this. Can anyone help? If so, he and
I would really appreciate you help.
Thank you in advance.
Hope at least some of you are having cooler weather than we are having here
in New York, where it is hot hot and humid humid!
All the best.
Veena

Hi,Veena
Here is a glaze recipe that I've sent ut before that is matt at cone 5.
Your friend may need to cut back the GB or frit a bit at cone 6.
Raspberry Base
Custer 27
EPK 9
Whiting 21
Silica 18
Frit 3134 9
Talc 8
Ger Bor 8
To make it blue-green, I'd put in maybe 1% cobalt carbonate, and then,
in one series of tests, add copper carbonate in 1% increments up to
about 5%. Then I'd make another batch, with the cobalt, and do the same
thing with chrome oxide. Somewhere in there should be a shade of
blue-green to your friend's liking.
And here in Seattle, we are indeed having weather that's not as hot as
yours. We had the furnace on for a while this morning. Once again,
we'll need coats to watch the fireworks.
