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)
Recipe:
10,5 Gerstly Borate
25 Neph. Syenite
36,5 Flint
18,5 Whiting
9,5 EPK
Add
7,5 Tin oxide
0,325 Chrome oxide
=20
All measurements measured up or down to the nearest whole decimal.
Substitutions:
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,
Alisa in Denmark
