In oxidation, Alberta Slip creates a glaze that is more transparent and lighter in color. It also melts less than in cone 10R so a little flux is needed (thus the use of the frit here). Since Alberta Slip is plastic, you need to use a mix of calcined and raw powder (see for information on preparation of the calcine).

Roasting Alberta Slip at 1000F

Roasting Alberta Slip at 1000F

Roasted Alberta Slip (right) and raw powder (left). These are thin-walled 5 inch cast bowls, each holds about one kg. I hold the kiln at 1000F for 30 minutes. Why do this? Because Alberta Slip is a clay, it shrinks on drying. Roasting eliminates that, a 50:50 raw:roast mix works well for most recipes having high percentages of Alberta Slip. And 1000F? Calcining to 1850F sinters some particles together (creating a gritty material) while 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.
