For what purposes are the different kinds? What properties of iron make it especially useful ? Can it be readily shaped as desired ? Can it be welded ? What iron industries are there in your community? What sort of raw material do they use? What are their chief products? Cast iron, which is converted into useful objects in very many localities, is easily worked and has a comparatively low fusing tem- perature. Visit, if possible, an iron foundry. Study the kinds of molds or patterns. What are t...he chief products of the foundry? What sort of iron is used for castings? How is it prepared in the foundry? How long a time is required to melt the cast iron? In what kind of furnace is this done ? What fuel is used ? Why ? World production. The relative tonnage of iron and other metals for a year shows the importance of iron in the world's production. We may take pig iron as equivalent to the total output of metallic iron. The production of pig iron in 1910 amounted to more than 96 per cent of the world's total output in tonnage of metals.
