I guess the dirt (lead oxide mostly) on the pool of lead, is both insulating the molten lead and keeping the oxygen away to some degree, so slowing down the formation of more lead oxide.
they simply collect waste from batteries, like destroyed positive sells, they crush them to dust, then they use a fire stove to bake it and at the end this thing changes color from black to orange-like and they again crush it to paste-like substance with water. lead simply stays at the stove, they later collect it and use to make lead rods with which they solder the cells back. it's like they constantly use batteries to rebuild themselves. if you noticed, all the negative poles are used ones, they cannot make them from scrap, they can only re-use them. making negative plates is impossible. unlike positive plates.

This is so awesome to watch.. Today, ppl call them selves mechanics when they only change parts in vehicles and have all the fancy tools. These guys make the parts and repair them for real on the floor.... Mindblowing.
People saying no masks no gloves its this simple moan and you do t work dont work dont eat dont eat well ye no the rest , this is not the west with all the health and safety crap
The lead 4 oxide and the metal is less dangerous but the yellow or orange lead 2 oxide is very toxic and easily absorbed through skin and metabolized. Just to make it safer they can pre wet the lead 2 oxide and wet mil it instead of dry mil. Working with dry lead 2 oxide is very very unsafe.
