Webster's 1913 Dictionary
  1. \I"ron\ ([imac]"[u^]rn), n. [OE. iren, AS. [=i]ren,
    [=i]sen, [=i]sern; akin to D. ijzer, OS. [=i]sarn, OHG.
    [=i]sarn, [=i]san, G. eisen, Icel. [=i]sarn, j[=a]rn, Sw. &
    Dan. jern, and perh. to E. ice; cf. Ir. iarann, W. haiarn,
    Armor. houarn.]
    1. (Chem.) The most common and most useful metallic element,
       being of almost universal occurrence, usually in the form
       of an oxide (as hematite, magnetite, etc.), or a hydrous
       oxide (as limonite, turgite, etc.). It is reduced on an
       enormous scale in three principal forms; viz., cast iron,
       steel, and wrought iron. Iron usually appears dark brown,
       from oxidation or impurity, but when pure, or on a fresh
       surface, is a gray or white metal. It is easily oxidized
       (rusted) by moisture, and is attacked by many corrosive
       agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9.
       Specific gravity, pure iron, 7.86; cast iron, 7.1. In
       magnetic properties, it is superior to all other
    Note: The value of iron is largely due to the facility with
          which it can be worked. Thus, when heated it is
          malleable and ductile, and can be easily welded and
          forged at a high temperature. As cast iron, it is
          easily fusible; as steel, is very tough, and (when
          tempered) very hard and elastic. Chemically, iron is
          grouped with cobalt and nickel. Steel is a variety of
          iron containing more carbon than wrought iron, but less
          that cast iron. It is made either from wrought iron, by
          roasting in a packing of carbon (cementation) or from
          cast iron, by burning off the impurities in a Bessemer
          converter (then called Bessemer steel), or directly
          from the iron ore (as in the Siemens rotatory and
          generating furnace).
    2. An instrument or utensil made of iron; -- chiefly in
       composition; as, a flatiron, a smoothing iron, etc.
             My young soldier, put up your iron.   --Shak.
    3. pl. Fetters; chains; handcuffs; manacles.
             Four of the sufferers were left to rot in irons.
    4. Strength; power; firmness; inflexibility; as, to rule with
       a rod of iron.
    {Bar iron}. See {Wrought iron} (below).
    {Bog iron}, bog ore; limonite. See {Bog ore}, under {Bog}.
    {Cast iron} (Metal.), an impure variety of iron, containing
       from three to six percent of carbon, part of which is
       united with a part of the iron, as a carbide, and the rest
       is uncombined, as graphite. It there is little free
       carbon, the product is white iron; if much of the carbon
       has separated as graphite, it is called gray iron. See
       also {Cast iron}, in the Vocabulary.
    {Fire irons}. See under {Fire}, n.
    {Gray irons}. See under {Fire}, n.
    {Gray iron}. See {Cast iron} (above).

       tacking, she comes up head to the wind and will not fill
       away on either tack.
    {Magnetic iron}. See {Magnetite}.
    {Malleable iron} (Metal.), iron sufficiently pure or soft to
       be capable of extension under the hammer; also, specif., a
       kind of iron produced by removing a portion of the carbon
       or other impurities from cast iron, rendering it less
       brittle, and to some extent malleable.
    {Meteoric iron} (Chem.), iron forming a large, and often the
       chief, ingredient of meteorites. It invariably contains a
       small amount of nickel and cobalt. Cf. {Meteorite}.
    {Pig iron}, the form in which cast iron is made at the blast
       furnace, being run into molds, called pigs.
    {Reduced iron}. See under {Reduced}.
    {Specular iron}. See {Hematite}.
    {Too many irons in the fire}, too many objects requiring the
       attention at once.
    {White iron}. See {Cast iron} (above).
    {Wrought iron} (Metal.), the purest form of iron commonly
       known in the arts, containing only about half of one per
       cent of carbon. It is made either directly from the ore,
       as in the Catalan forge or bloomery, or by purifying
       (puddling) cast iron in a reverberatory furnace or
       refinery. It is tough, malleable, and ductile. When formed
       into bars, it is called bar iron.

Tubal-Cain is the first-mentioned worker in iron (Gen. 4:22). The Egyptians wrought it at Sinai before the Exodus. David prepared it in great abundance for the temple (1 Chr. 22:3: 29:7). The merchants of Dan and Javan brought it to the market of Tyre (Ezek. 27:19). Various instruments are mentioned as made of iron (Deut. 27:5; 19:5; Josh. 17:16, 18; 1 Sam. 17:7; 2 Sam. 12:31; 2 Kings 6:5, 6; 1 Chr. 22:3; Isa. 10:34).
