    Iron ore subjected to that temperature does not melt, but instead results in a spongy mass (called "sponge" iron) mixed with impurities called slag. The iron worker removed this spongy mass from the furnace and then squeezed the slag out of it by hammering. This "wrought" iron had less tendency to corrode and had a fibrous quality from the stringers of slag which gave it a certain toughness.Онлайн-запрос
