Pennsylvania iron industry stood on the brink of a new era. The basic process of smelting iron in a blast furnace was fairly simple. The goal was to remove impurities from the raw iron ore by applying intense heat under controlled conditions, producing a purer and more workable product that could be further refined and shaped at a forge.

In this way, we can insure complete decomposition of the ore. One of the components is a lead oxide that is reduced to metallic lead. This metallic element collects gold and silver. The weight of flux is 25 grams. Basically, the flux must be able to control viscosity, degree of acidity, change the melting point of the ore and decompose the ore.
