Flameware Glaze #2

Original Recipe by Rob Probst (source)
Adaptation by Tetsuya Yamada

Orange-White Flameware #2 Cone 9/10

Custer Feldspar 6
Spodumene 4
Dolomite 4.5
Kaolin 5
Whiting 0.75
Tin Oxide 1

Total = 21.25

Matte opaque white with a very subtle blooming sheen on some portions. Breaks to ruddy orange. Oxide washes and stains run a LOT on the surface.

I've fired to Cone 11 (since that's when the clay body vitrifies) and it's been fine; no change in colour.

~Colorants~

Add 2% Cobalt for a nice blue that breaks to black.

Most stains burn out. Other colorants that work: Vanadium or Ferrous oxide, black mason stain (number unknown), Copper Oxide

Update: Test tiles
Glaze brushed on over some colored spots. Thin to thick.
Some washes applied on top.Most burned out.
Fired Gas Cone 10 unless otherwise noted.
From to, left to right: Vanadium Yellow or Yellow FE oxide; Tin oxide (bubbles); CuCo2; Al Pink (?); Crimson stain; Black stain; 3% Cobalt Oxide Electric Oxidation Cone 10/11
