In the glaze fire: the most important firing schedule in this case would be the last 120F: which I would slow down to 60F an hour with a short hold. Getting the clay mature is the most important issue in this case: and then find a glaze that matches the peak temp and the body.
Unless I misread what Infinite said I don't think it can be fired at that speed. Sounded like the only option was full on after hitting 600C. Before then only 4 ramp options, 60C being the lowest. I was suggesting slowing down towards the end of both the bisque and glaze but I don't think it can be done with her kiln.
