test 5

V.C. "D" Base with Cobalt Carb
Cone 6 Oxidation

Kona F-4 51.0
Whiting 19.0
Zinc Oxide 9.0
EPK 15.0
Flint 6.0
Cobalt Carb 1.0

Semi-Satin Glaze. Charming glaze that transitions from a subtle periwinkle (i cant think of a word to describe this purplish blue, and I apologize that I chose periwinkle as a descriptor)to a strong saturated pastel blue. The transition between colors marks and highlights the movement of this glaze that again adds exciting depth to a traditional satin blue.

This glaze is one of 18 tests. Students of the fall 2009 semester tested in 100 g. batches, recalculated to assure glaze stability, then further tested 500 g. batches, and finally compiled a list of 18 glazes to go through a uniformed batch test. All batches of this 18 recipe set were mixed through a process of precise measurements, 60 and 80 mesh screening, were dipped on cone 04 bisque for 3 seconds, and were finally fired to a witnessed cone 6 oxidation in an electric kiln. (Firing schedules are to follow shortly).
