>Jan: Regarding your recipe for Rutile Blue (Clayart Feb. 7/98), where is
>the cobalt?

Laurie: There is no cobalt in this formula. The glaze is a frosty,
creamy,pale blue in reduction, and looks very good over temmoku. Anyone
wanting a deep blue shouldn't expect it from this glaze. In fact, without
proper reduction, the result is more of a tan/cream. The article in
Ceramics Monthly described it as a Rutile Blue.
