Note the redder appearance? I figured out I could get all kinds of different colors if I first sprayed the porcelain with my oribe glaze -- basically coat it with lots of copper.
These were some of the bowls I did for the Goshen Empty Bowls a couple of years ago. One third were lined in oribe, one third in cobalt, and one third plain.
Celadon is hard to photograph, but again you can see the depth of color added when sprayed with oribe glaze first.
What is the oribe glaze? It looks beautifully dark and luscious! I have one similar that takes 15% of yellow ochre !!
ReplyDeletelove the bowl with the cut rim. very subtle and beautiful.
ReplyDeleteyou had me at amber.....
ReplyDeleteI'm with you, Meredith. :)
ReplyDeleteIt IS a nice glaze. Here's the recipe if you are interested. If you substitute Alberta or any other Albany Slip substitute, you will just get a green celadon.
ReplyDeleteOhio Slip 330
Custer Feldspar 200
Wollastonite 130
Gerstley Borate 30
Whiting 70
EPK 30
SIlica 130
Yellow Ochre 70
Oh, and an oribe glaze is a glaze that's VERY high in copper -- usually it ends up with an almost iridescent, transparent, dark green surface.
ReplyDeletedreamy glazing
ReplyDeleteThanks for the recipe. I'll have a try in the next glaze firing, any day now
ReplyDeleteDo you mean sub for the Ohio slip?
What does the GB do in the glaze? It isn't something I'd normally use
Since you don't have access to Ohio Slip, you can try whatever "self glazing clay" like Albany Slip is available. I've just noticed that the subs available on this side of the pond make a nice glaze -- but it's definitely NOT amber with the other substitutes. It IS amber with Ohio Slip and with the now extinct Albany.
ReplyDeleteAs far as Gerstley Borate: I think the British equivalent was Colemanite, but I think that may be extinct as well. Here's a discussion of substitutes that might be useful:

I was wondering if there was anything without Boron that would do it. I googled and found the old threads on clayart.
ReplyDeleteGB provided much calcium and sodium if I remember rightly, too.
I think Colemanite is still available-I've used it before and it was a nightmare!!
