Lol. Also, if the lead is hot enough, the flux will catch fire. As a rule, I start my flux aflame anyway, as it helps the cleaning process. Wear gloves, long shirt, pants, boots, eye protection. Stir with a long handled stainless steel spoon. Use it to drag/dip off your dross. You can't be too careful while fluxing and cleaning lead. Always outside, no chance of rain(molten lead and water don't mix), and stand upwind. Don't breath the airborne flux compound/mix. Use precautions and understand the process and you'll be fine.
