Shera's Copper Rainbow
Cone 6 Oxidation

Recipe:
Custer Feldspar 35
Flint 16
Zinc Oxide 17
Ball Clay 12
Wollastonite 20
+
Copper 4

Evaluation:
This is an expressive glaze that transitions from teal to turquoise, and displays the motion of the glaze. The motion of this glaze is waterfall in effect, and additionally transitions from translucent to opaque on the peeks and ridges of the clay texture that adds a charming depth to the glaze. The translucent sections of this glaze are a leafy organic green celadon that emphasizes the creamy and rich teal/turquoise. It is a bit unstable, however well worth working with. High gloss.

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).

EPK 1.3
Flint 5.2
Gerst Bor. 15.0
+
Red Iron Oxide 9.0

Evaluation:
Very unstable. As an exterior glaze this is incredibly runny and drippy. This may be a nice liner glaze, and pools in the base of a cup to a rich deep black/brown.

+
Red Iron Ox 7.15

Evaluation:
This is an alteration on the traditional tomato red recipe. It is unstable, but spots nicely to rusty red through dark brown. It is high gloss and has nice potential, but needs work on dripping.

Talc 8
Bone Ash 2
+
Copper Carb 6.5

Evaluation:
This is a stable transulent and high gloss glaze that transitions from the lip of a cup to the base with a crisp transparency to a rich deep oribe. Reminds me of the transition from shallow to deep water.

Whiting 4
Zinc Oxide 2
EPK 7
Flint 40
+
Rutile 8

Evaluation:
Again the 72 base glaze is an incredible and stable base glaze. With the addition of Rutile the 72 base is a visually rich buttery glaze. This combination captures the movement of the glaze and highlights the peeks and dips of the clay body texture.

This is an opaque and stable glaze. The 72 Base doesn't allow for rich color translation, however this pale, pale, pale violet is a beautiful twist on pastels.
