Glaze test for Cranberry Glaze, cone 6, oxidation.
Source. Don Goodrich sent by Ababi.
Tested on light, mid-range stoneware, with iron flecks. Fired to 1215c =
(22219) 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)

10,5 Gerstly Borate
25 Neph. Syenite
36,5 Flint
18,5 Whiting
9,5 EPK

7,5 Tin oxide
0,325 Chrome oxide
All measurements measured up or down to the nearest whole decimal.
Local frit for G.B.

Resulted in a haxy pink gloss. No difference where double dipped. Iron =
flecks came through and glaze stayed where appiled.

Added 10% Alumina Hydrate.
Matted above glaze with a slightly dry texture.
Need to retest both above after glaze has soaked longer for hopefully a =
darker plum.

Best regards,
