| Material | Amount | Percent |
|---|---|---|
| Alberta Slip 1000F Roasted | 33.00 | 35.5 |
| Alberta Slip | 40.00 | 43.0 |
| Ferro Frit 3134 | 20.00 | 21.5 |
| Added | ||
| Zircopax | 4.00 | 4.30 |
| Mason 6666 Black Stain | 3.00 | 3.23 |
| 100.00 | 100 | |
Notes
A glossy black. The small amount of frit needed is due to the fact that Alberta slip is a dark burning material already. If it is not black enough, increase the percentage of stain. If you need a glossier surface, increase the frit. If it crazes switch to Ferro Frit 3195. Should be ball milled.
For mixing instructions please see the master recipe, GA6-A.

Roasted Alberta Slip (right) and raw powder (left). These are thin-walled 5 inch cast bowls, each holds about 1 kg. I hold the kiln at 1000F for 30 minutes. Why do this? Because Alberta Slip is a clay, it shrinks on drying (if used raw the GA6-B and similar recipes will crack as they dry and then crawl during firing). Roasting eliminates that. Calcining to 1850F sinters some particles together (creating a gritty material) while roasting to 1000F produces a smooth, fluffy powder. Technically, Alberta Slip losses 3% of its weight on roasting so I should use 3% less than a recipe calls for. But I often just swap them gram-for-gram.
