Variegation was also being tested on this piece. This is also a single application, with additional glaze loaded on the neck. At the base of the neck, I had applied a chemical barrier to prevent the glaze from running any further than I had marked. The copper broke to the blue side, and likewise cream colors broke through as well (in a single application). The more remarkable result: this glaze has a Si/AL ratio of 9.25; which should have produced a very high gloss. I add 2% of an optically negative element, which resulted in a nearly matte glaze.

Brushing, not spraying. The base glaze is blended well, sieved. Then I come back and add oxides and some other elements that causes the oxides to separate. The variegation is chemically induced.. in easy terms.

Babs: I stumbled upon a little secret years ago while doing crystalline glazes. There are two rare earth oxides; if added in the proper portions causes other oxides to separate. in lieu of their usual blending.
