Opaque tan glaze. This is an interesting glaze with transitions between dusty tan and leather tan. From a distance this glaze translates a solid tan, however up-close this glaze has allot of charcter and expression. A bit unstable, however altering the gravity or thinner application may resolve dripping. This glaze will be tested again under the same name (test 3 from Fall 2009)and re-posted. Inital test showed the gravity and application to be correct, however this is a glaze worth perfecting. Please check back for alternative test results and images.

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).
