Lead smelting pots come in two types: those heated over fire and electric versions. The latter is commonly used for home projects, while industrial smelting uses both. Protective gear is necessary due to toxic fumes. Electric pots are the most efficient and can use chemical additives to prevent sticking.
Lead pans come in two basic types: the type that is held over a fire until the lead melts, and the electric version that uses an electric heating coil to heat the lead pans to melt the lead ingots into the lead pan. ‘internal. The electric version of lead smelting pots is the most common in use for home smelting projects, while industrial grade smelting uses a blend of both versions, albeit on a much larger scale. Lead smelting can be performed to produce a wide variety of components, from wheel balance weights to fishing sinkers and muzzle-loading accessories.
Typically made of heavy cast iron, lead cookware can survive the repeated heating and cooling cycles associated with lead smelting. Lead is commonly purchased in large blocks requiring the use of lead smelting pots to smelt it for pouring into casting molds. The danger in lead smelting is in the toxic fumes escaping from the lead pool. Protective clothing, respirators and goggles should always be worn regardless of the type of lead smelting cookware used. While small household lead smelting pots use ordinary household current to melt lead, large industrial lead smelting pots commonly use carbon or extra high voltage rods to create enough heat to melt large quantities of lead in a single pot. .
Carbon arc lead smelting pots use carbon rods and electricity to create an arc much like a welding arc to create the heat needed to melt large quantities of lead ingots. As the charcoal arc burns under the large cast iron cauldron, care must be taken not to burn through the cast iron. Experienced workers ensure that the heat is controlled and that the lead melts as quickly as possible. Some old mills use a coal or oil fire to heat large cast iron pots to temperature.
The most efficient type of melt pot is the electric pot. These lead pots use electricity to heat and melt lead similar to a small household pot, but on a much larger scale. The elements can be placed under the pot or inside the pot, depending on the design, and can reach the desired temperature in a very short time. Chemical additives are often used to prevent lead from sticking to the pot, however, in an industrial grade cauldron, the lead is melted round the clock, thus eliminating any problems with lead left in the pot.
