There have probably been about a hundred reds posted here, but here's another
we commonly use at the Potters Studio in Berkeley. It gives a bright red
normally - a little darker perhaps than a real strawberry red, but is pretty
reliable. We start the reduction early in the firing, usually by the time
010 is going down..

Pablo's Red

Custer Spar 46.8
Flint 20.0
EPK 2.5
Whiting 8.3
Gerstley 13.7
Zinc Oxide 4.0
Dolomite 6.0
Tin Oxide 3.0
Copper Carbonate 1.5
Ferric Oxide 0.5
