For Seju, I used a glaze called Temmoku Gold. In its first mix, seen here, it was black with gold flecks. The next time it was mixed, it came out a sparkly gold color which I also used extensively. The third mix came out a matte gold which I never bothered to use. Unfortunately, the entities responsible for mixing glazes at Tucson Clay Coop have not been able to recreate either of the first two interesting versions of Temmoku Gold.
Zesty has the letters Z - E - S - T - Y imprinted on the points of its base because it's fun to play with letter stamps.
