Also, the melting point of aluminum is not all *that* much higher than lead (Lead is 327.5 deg C and Aluminum is 660.3 deg C - compare this to Copper at 1085 deg C and Iron at 1538 deg C). It is possible that you were beginning to melt the aluminum on the kitchen stove, too. As it approached its melting point, it is likely that it would alloy more easily with the already molten lead.
