This is Amaco PC-20 Rutile Blue. These mugs are the same clay, Plainsman M390. Both were brush-on glazed the same way. The one on the left was fired to cone 6 using the C6DHSC (drop-and-hold, slow-cool) schedule. The one on the right with the PLC6DS (drop-and-hold and free-fall) schedule. The label on the jar just says to fire to cone 6. But this is a rutile blue, and behaves like one. Since most people would fire fully loaded kilns slow cooling is a natural consequence of this and the color should be blue. That being said, variations in density of pack will still produce variations in the way this turns out. If you fire in a small kiln, the way we do, then it is necessary to program the cool cycle of the firing to be sure it does not drop too fast.
