I’m a bit cloudy on the source of this glaze, but I seem to remember receiving it from Karen Sullivan who taught ceramics at Cal Poly Pamona College in California (I think) when I attended a firing there with Phil Cornelius. I know I wrote the recipe down wrong as the %’s were way off, so I played around and made a few adjustments and this is what I got, which I really like. If anyone has Phil’s email address I would love to send him this image and see if he would help me get back to the original.
Notes: This is a ∆10 Reduction glaze that loves a 30 minute soak at the end of the firing with the kiln being closed in reduction. This glaze is more of a specialty shino type glaze, that depending on clay body and thickness of glaze application will range from a golden almost metallic to a light yellow with an unctuous soft finish. Really looks good over high iron clays. This glaze will carbon trap. For carbon trapping start your reduction at 1560-1570F. Please test this glaze for your firing conditions.
