Roger & Dave - here's the recipe for KAREN'S TOUCH GLAZE.
C/10 OX or REDTN
Kona F-4 feldspar 45
Dolomite 18
Whiting 4
EPK 9
Calcined kaolin 10
Tin oxide 4
Flint 10
Total 100%
Red iron oxide 1
Bone ash 4
Should read 7 ingredients totalling 100% plus two additives.
Surface: Satin Matt Light transmission: Opaque
Color: on porcelain in OX THIN = warm rusty beige breaking to
copper rust on rim & ridges THICK = warm beige w/ copper
rusty rim Both thin & thick show very fine rusty flecks
On porcelain in REDTN THICK = almost sea foam greenish w/
orangey copper rust w/ flecks where thin
I consider this to be a glaze which in OX looks like REDTN -
for those of you who pine for that.
As I previously mentioned, in OX put it over PORCELAIN SHINO
& you get a funky rough surface in solid copper w/ fine
rusty flecks - this is thin. Thick edges are unattractive (?)
white.
If firing in REDTN, slow cool for max. orange.
This is a variant of the famous Mamo glaze. If you want to
try other colorants, drop out the tin (it's incl. to promote
ornage) from the base as well as dropping the RIO & bone ash.
But BE CAREFUL - this glaze pulls apart if too thick in big
fatal crawls. I abandoned it as a white for this reason
& I swear it once pulled so badly it broke (?) the pot it
was on. This was not the above version however.
Good luck & enjoy. Karen Gringhuis
