<asked me to put a search out for a lost glaze. She calls it Cobalt Green,
is cone l0, "almost black green satin matte" found in Ceramics Monthly
several years ago(a search through my collection did not turn it up), uses
cobalt and rutile and may have been under the questions section. If this
rings a bell with any one, could you please send it to me or the whole group
and I shall send it on to her via snail mail. Thanks a bunch.

This seems same glaze to me; I find it fires a very nice
blue (instead of green) in oxydation:
REITZ GREEN MATT (via Val Cushing): ^9-10 Reduction.
70 Neph Sy
15 Petalite
8 Ball Clay
5 Whiting
2 Gerstley Borate
Add: 1% cobalt carbonate, 1% Rutile
Thin: dark, near black; thick: smooth deep green. Opaque.
