Glaze test for William Edwards' Red #3=A9 , cone 6, oxidation.
Tested on light, mid-range stoneware, with iron flecks. Fired to 1220c =
(2228f) oxidation, at this ramp:
100c to 600c 212f to 1112f
150c to 1100c 300f to 2012f
100c to 1220c 212f to 2228f
soak at 1220c for 30 minutes =20
cool down 100c per hour to 900c (212f/1652f)=20
soak at 900c for one hour
shut off and cool down (aprox. 40 hours)
Recipe
24 3134
10 Neph. Sye
16 EPK
20 Whiting
26 Flint
2.5 Talc
1.5 G200
ADD
5 Tin ox.
0.35 Chrome oxide
Subs: =20
Frit 169 for 3134
Forshammer for G200
Resulted in a smooth gloss glaze, with an underlying grey to pink fluid =
colors under gloss "shell". Some signs of burgandy where thickest at =
top of tile. Stayed where dipped and no discernable difference where =
thicker. I believe like the Rosenrot, I should let this glaze soak =
longer before using to get the deep burgandy. However, it is quite =
understated and nice on this test.
Best regards,
