I was taken with the CM article on Chun Blues. Anyone have a good recipe for
this type of glaze? I work in oxidation cone 9-10 but I don't think
atmosphere is vital, is it?

Malone,
Atmosphere is very important in cleadon and chun blues. Without stong
reduction the iron (1 - 2 %) will make the glaze green rather than blue.
I could refer you to several books on the subject, like Tichane, "Those
Celadon Blues" or "Stoneware Glazes " by Ian Currie. Both are awesome
reference manuals.

Aloha Tom (and others);
Have you seen the Ceramics monthly article on Chun blues? Issue before last,
I think. The author states that similar results were obtained in oxidation
and reduction. This seems like a different type of glaze than a celedon.
Anybody ever made one with commercial ingrediants? The author uses local,
African, ash which is hard to obtain on Kauai
