test 8


"72" Base with 10% Crimson Mason Stain
Cone 6 Oxidation

Recipe:
Neph Sye 24
Dolomite 11
Gerst Bor. 12
Whiting 4
Zinc Oxide 2
EPK 7
Flint 40
+
Crimson Mason Stain 10

Evaluation:
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.

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).
