Well, I got a new mold and had to try it out of course, and so far its doing real well. My question is, if you are only half way done casting the number of boolets you want, and you have to run in and eat lunch, what do you do with your hot, electric lead furnace while you are in eating for a half hour? Do you leave the mold on the heating tray on top and turn the temperature down a little and go eat? Warming it back up to casting temperature when you get back? Or turn it all the way off and then back on again when you get back? Mine takes about 20 minutes to get up to temperature when it is cold.
