Hi all,
Here are a couple of C 6 glazes that I use with my speckled brownstone in ox.
Both are from Electric Pottery by E. Cooper.
Hatch Base Matt
potash feldspar 40
zinc oxide 15
china clay 20
whiting 25
A very even matt when well applied. Below C6 can be dry and scaly. The
success of this glaze depends on the clay body. As stated from the book. I
like the way it looks with Randy's Red and I have used it in combination
with other colored glazes with good luck.
Superglaze
georgia kaolin (china clay) 9.9
flint 18.2
zirconium silicate 17.3 I use zircopax
zinc oxide 15.8
lithium carb 8.5
nepheline syenite 15.0
whiting 15.3
A very fine, strong, white glaze with a soft sheen. Opaque. I love the
white color of this glaze. Since it turns to cement when it sits, I have
started adding bentonite, which helps. It works well with other glazes that
have color. jan.
