Eyeball for austenitizing, then tempering in the kitchen oven. I heat the blade for austenitizing inside of a black iron pipe in the forge. It helps even out and control the heat as well as letting me keep a reducing atmosphere by putting some charcoal in the pipe. I've only worked with 0-1 to this point, but my results have been excellent. The curie temp, where the steel becomes non-magnetic, is a bit low for austenitizing 0-1.
