Simon Leach Pottery video - entitled Pitcher double dip + PB glaze recipe

https://www.youtube.com/watch?v=GQgp9FtYoFE&list=PLDDEBe7QOmgGe...

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. :(

cobalt

red iron oxide

manganese dioxide

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.

reply by Simon Leach about Blue Wash recipe on his video:

Hi CP

The blue wash is 

25% of each of these :

Cobalt oxide

iron oxide

manganese dioxide

dry crushed porcelain clay

Sieve all ingredients - 100 mesh

Use as a decorating pigment or watered down as a wash. Experiment with application thickness.
