IMO the biggest mistake people make pouring lead is getting it too hot. the amount of fumes coming off the lead is like a square of the temp above the melting point. That means you get about 100 times more fumes if you are 400 degrees above the melting point than if you are just 100 dgerees above the melting point. if the jigs don't fill the mold , don't up the lead temp....preheat the mold instead. Also turn the setting down on the automatic lead pits whenthe pots gets about 1/2 empty. the temp of the remaining lead goes up when the pot is not full and this sets it fumimg heavily. We always pour outside. never pour lead with small children around.Lead is bad for adults but for some reason , babies and kids suck up the lead fumes like a sponge. In a child , lead leads to permanent brain damage. Don't take any chances.
