"72" Base with Vanadium
Cone 6 oxidation

Recipe:
Neph Sye 24
Dolomite 11
Gerstly Bor. 12
Whiting 4
Zinc Oxide 2
EPK 7
Flint 40
+
Vanadium 5

Evaluation:
Unsure how to describe this glaze. Visually it looks dry, however the pooling and separation of color is quite glossy. Their is an extreme separation of color in this glaze that is visually conflicting with tactile assumptions. Their is almost an oily separation. In places where an initiation of a drip begins, the best analogy I can come up with is olive oil mixed with butter. The opaque coloring (butterish) almost floats on the clear olive oil gloss. Interesting glaze!

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).

Red Iron Oxide 9.0

Evaluation:
Extremly unstable. The positive qualities...transitions nicely from matt to gloss, and the interior pools to a rich and deep black/brown. However this glaze runns! Only use on top half (if not higher, top third).

Evaluation:
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.

Evaluation:
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.

test 1

Black
Cone 6 Oxidation

Recipe:

Evaluation:
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.
