This glaze is from "Glazes for the Potter" by
Emmanuel Cooper next to color picture #4
adjacent to page 65.
Barium carbonate glaze with copper carbonate
(stoneware 2300 f.)
soda feldspar 25
dolomite 15
china clay 25
bone ash 10
flint 25
+1.5% copper carbonate
Is it me or should there be a quantity of Barium
Carbonate?

I am starting a series of crater glaze and slip tests so just happened to
have the book on my kitchen table. My book says "Deep turquoise glaze with
copper carbonate" and gives the recipe as you have it. It photographs a
nice blue. Please let me know how it turns out.

Dear James L Bowen,
I think this is an editing error on the part of the authors. Usually due =
to poor proof reading. They do give a Barium Blue in the appendix.
Ivor.
