Dear Clayart,
I tested this recipe a while a go when it was posted to the list.

Phila Green, redux. cone 6

58 Neph. Sye.
26 Strontium Carb.
10 Ball Clay
5 Silica
1 Lithium Carb.

4 Rutile
4 Copper carb.
4 Bentonite
1 Epsom salt.


The test showed a matte green with a slight pink tinge on the surface in =
some areas of the tiles.
John H. told me this glaze is an underfired matte at cone 6.

I painted some small bowls with the left over glaze, thickly.

They fired to a red pink matte.

The red pink color is similar to the Pink and Blue Matte glaze in Hamer =
and Hamer, page 401 by Emmanuel Copper.
That glaze has Nickel ox. as the colorant. He says that 1-3% Nickel, =
20-50% Barium carb and 10 Zinc oxide can produce these pinks, blues and =
greens (in the same glaze)

I am wondering what property Phila Green glaze has to produce such a =
broad spectrum of colors with a varied application?
