Fired at cone 6 using the C6DHSC schedule. On Plainsman M340 and Buffstone. Left: Alberta slip with 20% Ferro frit 3195 (GA6-B). Right: Alberta Slip with 20% Fusion Frit FZ-16 (G3903). This Fusion zinc frit is a super-melter, much better than 3195. A picture cannot do this glaze surface justice! The zinc brings out the red coloration much better. Frit FZ-16 is not readily available, we are hoping companies will eventually stock it. And it produces a more brilliant glassy surface that highlights thickness variations even better. Adding a little extra iron oxide (e.g. 1-2%) would make the effect even richer.
GA6-B - Alberta Slip Cone 6 Amber Base 2
An amber-colored glaze that produces a clean, micro-bubble-free transparent glass. Works well on brown and red burning stonewares.
