I've used this glaze before, I found it in John Britt's Cone 10 glaze book. Its an extremely interesting glaze, being light tan, pink, white over light clay bodies, and with more green and blue flecks over dark stoneware. A friend of mine sprayed a temmoku very lightly over this glaze, giving it a deep iron blue gradient.
