I dug this one out of the Clayart archives:
Perkins Cone 9 oxidation Copper Red
Nepheline Syenite 126.10
EP Kaolin 16.00
*Zinc Oxide Calcined 16.40
Whiting 42.60
Talc 12.50
Flint 84.30
*tin oxide 1.80
*Silicon Carbide 1.20
*Copper Carbonate 1.80
302.70
I divided by three to get convenient numbers to mix a test batch of 1000 =
grams
Ball milled the granular silicon carbide to a nice powder, and used =
regular Zinc Oxide.
Then applied a thick layer by dipping
Fired to cone 9 Electric- (10 in the sitter)
I was accidently paying attention this time and put it up on a stilt so =
just the drippings ran all over the kiln shelf, and were easily removed
The result:

( I'll be doing this again)

From the left:
Rhodes Stony Matt plate
Two Celadon Ash
0.25% Cobalt carbonate in Phil's Nuka (see above) (pasty)
Artifical reduction with Silicon Carbide to get copper red.
10% Rutile in Nuka (it pits)
New batch of Karatsu Tenmoku with rutile decoration
Artifical reduction of John Jelfs Ochre Ash
1% Copper carbonate in Nuka over white slip - I need a gun.
Actually I got the gun, but the compressor was damaged and had to be =
sent back.

Hi Rick,
You might want to try it without the zinc oxide - it may not be necessary.
The reduction may have eliminated it.
