    1 day ago  The first problem is time: carbon absorption for hot-but-solid iron (like an iron-bar in the forge) is relatively slow, often taking hours (one experiment suggests about three hours to completely steel a 3mm thick piece of iron, with thickness increasing the time required non-linearly). But irons are generally left in the forge fire only for minutes, which would mean that even if any ...

  • Ferrous metallurgy - Wikipedia

    Iron smelting—the extraction of usable metal from oxidized iron ores—is more difficult than tin and copper smelting. While these metals and their alloys can be cold-worked or melted in relatively simple furnaces (such as the kilns used for pottery) and cast into molds, smelted iron requires hot-working and can be melted only in specially designed furnaces. Iron is a common impurity in ...
