I was casting some boolits Sunday AM, and ran down the load in the furnace, so I added another 5 lbs of alloy to the 1-2 lbs already there, cranked the control up high, and went in to check eBay. Ten-fifteen minutes later I went out to resume - and DANG! The thermometer said 900*! I looked in, and the level was pretty far down - ??? Then I looked under the furnace...
I hate it when this happens...
