Cone 6 Oxidation
This glaze is a rich black with exciting depth. It has the characteristics of gas pooling in water. An extremely stable glaze with a visualy oily or tar like movement that captures time. From a distance caries a strong gloss black presence, however when viewed up close is expressive and transitions with iridescent(ish)movement. In this test the overall gravity and application of 3 seconds was a hair too long. The dripping view within the immage is not a result of an unstable glaze, rather application should be changed, or a small addition of water would produce a more stable hold on the cup.
NOT FOOD SAFE
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).
