Simon Leach Pottery video - entitled Pitcher double dip + PB glaze recipe
Simon uses an off white glaze as a base "PB", which he then paints with a blue wash, and "an iron oxide."
the PB off white glaze is discussed in the video, and is a cone 10 reduction
any chance we can modify in oxidation, cone 6 ? (white stoneware)
this is similar to light greyish base pots with cobalt and/or iron oxides applied, which is the general effect i am looking for
recipe listed on the video, and for completeness is listed as follows:
PB glaze - from Bernard Leach’s recipe , he doesn't know what PB stands for
Off white base glaze
Flint 4 lbs
Kaolin 2 lbs 12 oz
Feldspar 3 lbs 14 oz
Whiting 1 lb 14 oz
Talc 1 lb 2 oz
Blue wash: no amounts listed. :(
red iron oxide
iron oxide - no idea what recipe :(
thanx for help,
cp - on the pond, which is overflowing due to beavers blocking the outflow.
The old standby trick to reduce the maturing temp of a cone 9-10 glaze is to replace 50-100% of the feldspar with nepheline syenite. This is guaranteed to work perfectly - Not!
The dipping technique, from the video, where you don't have to wax the feet is terrific.
Adding red iron oxide, however, that might give you gray-green in reduction, is likely to remain brown in oxidation (the celadon variation Simon was talking about). You might need to go to a different colorant or stain.
thank you kindly
