3 methods of dating artefacts

Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past.The process of radiocarbon dating starts with the analysis of the carbon 14 left in a sample.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.The sample-context relationship is not always straightforward.Date of a sample pre-dates the context it is found.

Carbon 14 dating remains to be a powerful, dependable, and widely applicable technique that is invaluable to archaeologists and other scientists.Other potential contaminants include paper, cardboard, cotton wool, string, and cigarette ash.Samples must be stored in packaging materials that will protect them during transport and even during prolonged storage.Contaminants must not be introduced to the samples during collection and storing.Hydrocarbons, glue, biocides, polyethylene glycol, or polyvinylacetate must not come in contact with samples for radiocarbon dating.
