Fired Stoneware
My
stoneware pieces are wheel thrown. After a usual bisque firing,
I apply a single colored glaze to the entire piece either by
spraying or dipping. Then, without preplaning, I use a variety
of plastic drafting templates as guides and spontaneously scratch
designs on the piece. In addition, some areas are scraped totally
free of glaze. To obtain multicolor effects I stain areas of
the unfired glaze with soluble salt solutions (copper sulfate,
cobalt sulfate, etc.) See my articles, "Using Soluble
Colorants at Stoneware Temperatures" in the Sept. 1996 issue
of Ceramics Monthly magazine and "Wild Decoration"
in the Sept./Oct. 2002 issue of Pottery Making Illustrated
magazine.
I
use the following glaze with various colorant additions almost
exclusively:
| Cornwall
stone |
60 |
| EPK |
20 |
| Dolomite |
20 |
The pieces are then fired to cone 10 (2350 degrees F) in a reduction
atmosphere in my 20 cubic foot propane fired kiln. |
