It is the most precious metal in the world because it is the most useful. Without iron to make our stoves, kettles, knives, tools, engines, and railroads, we would be living today very much as the Indians lived when Columbus discovered America. Our cooking utensils, our tools, and our weapons would, to this very day, be of clay or wood or stone. Pound for pound, pure gold is, to be sure, worth more than pure iron. But when it is made up into useful articles, iron may be worth more than a corresponding weight of gold. A bar of iron, for example, worth five dollars, is worth ten when made into horseshoes, fifty-five dollars when made into needles, three thousand dollars when made into knife pen blades, and twenty-five thousand dollars when made into balance springs for watches. © Copyright 2022 Adamorbis, LLC.
