Carbon dating not useful artifacts made metal
Characteristics: Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity.
Harmful effects: Iron is considered to be non-toxic.Iron corrodes easily, so iron artifacts from ancient times are much rarer that objects made of silver or gold.This makes it harder to trace the history of iron than the less reactive metals.Alpha iron, also known as ferrite, is the stable form of iron at normal temperatures.Iron is the cheapest and most important of all metals – important in the sense that iron is overwhelmingly the most commonly used metal, accounting for 95 percent of worldwide metal production.
