Radiocarbon dating iron is not technically feasible, but cast iron does contain about 4% carbon. Before 1700, it was made by adding charcoal to the molten ore. Charcoal is made from organic material which can be radiocarbon-dated to give the time of manufacture of the object.
Can iron be carbon dated?
Iron artefacts are generally dated by association or on stylistic grounds. If the fuel is of a material containing contemporaneous carbon, i.e. has an ambient radiocarbon signature, e.g. charcoal, then we may reliably radiocarbon date the artefact by extracting this carbon.
There isnt an intrinsic method of dating metal as there is for wooden objects such as radiocarbon-dating or tree-ring dating. Much depends on the assessment of the object. For instance, an axehead made of bronze is likely to date from the Bronze Age, before knowledge of how to make iron.
For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
Can you carbon date rust?
The role of rust in the radiocarbon dating of iron artefacts has been examined experimentally. The results demonstrate that in at least some circumstances the carbon in rust can be reliably used for radiocarbon dating.

There are three main types of metals ferrous metals, non ferrous metals and alloys. Ferrous metals are metals that consist mostly of iron and small amounts of other elements.
Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite .Diamond and graphite.DiamondGraphiteHardSoft1 more row
The Metal Age is divided into three stages: the Copper Age, the Bronze Age and the Iron Age. During the Metal Ages, people made a variety of metal objects. They also invented new techniques for making clay pottery. During the Metal Ages, people started using large blocks of stone called megaliths to build monuments.
approximately 5000 years BC Ancient man first found and began using Native Metals approximately 5000 years BC. Over the next 2000 years, leading up to the Bronze age, man mastered how to find, manipulate and use these native metals in better ways and in a range of applications.
