Just perusing raw materials inventory to make some glaze recipes and I've g=
ot a lot more cobalt oxide than carbonate and recipes call for cobalt carbo=
nate. Here's a very handy conversion formula: divide carbonate amount in re=
cipe by 100 X 63 =3D oxide amount; divide oxide amount in recipe by 63 X 10=
0 =3D carbonate amount. Please note that this is for cobalt only. It beats =
the if you're looking for stable and safe glazes for dome=
stic use.

Very useful
Is there a similar conversion formula for Copper oxide/carbonate?

Thanks again!
This gets me thinking about other colourants we use! What is the
difference between Yellow Iron Oxide and Yellow Ochre? Is it just that th=
e
oxide is constant, the ochre can vary(and have metals other than iron in
it) and possibly have some clay in it , from the feel of it.
What is special about Black Iron Oxide?
