I am new to pottery, I am in need of a blue glaze that breaks brown for cone
6 oxidation. Any help would be appriciated.

Hi Gene,
You probably have all the blue glazes you
want by now, but just in case you don't here
is one called 'Blue with brown spots'. We used
it a lot at one time (don't really know why we
semi-retired it as it is a good glaze).
Zircopax---------10
Cobalt Carb-------1
Rutile------------1 (!/2gran. & 1/2ceramic is
Coemanite(or GB)-50 good)
EPK (Kaolin)-----20
Flint------------30

Another glaze that we do use a lot is an
Amy's Blue. It is a washed denium blue and
is a great semi-matt. It does have a lot of
Barium however, so Ron Roy would suggest you
work with Strontium Carb instead. We do non-
functionals and haven't tried the Sr yet.
Amy's Blue:
Barium Carb------18.4
Dolomite---------11.1
Whiting----------4.7
Nephsy Synite----28.6
EPK--------------7.4
Flint------------21.5
Tin Oxide--------2.8
Zinc Oxide-------2.8
Copper Carb------1
Add Cobalt Carb--0.35

Hope they work for you-let us know.

Hi Reg,

You are right - Ron says don't use it where it can come in contact with
food - it's short of silica and the copper is going to make it worse. I'll
bet I can make it change colour with some foods.

Even if you sub in Strontium - it may still change colour under some
circumstances.

Just so you all know - RR

Ultrox, and rutile are "spot materials" I believe it will work work other
bases too, no need to dig G.B.
