In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.The method could eventually be used for a variety of other analyses."Potentially, you could date any other material that has preserved organic compounds," like pitches from wood products or collagen from bones, according to Evershed."We're taking a piece of pot and grinding it to a powder, and then extracting lipid that's penetrated right down into the fabric." The researchers used a technique called preparative capillary gas chromatography to isolate the lipids, then they radiocarbon dated purified compounds with an accelerator mass spectrometer located at the Oxford University Radiocarbon Accelerator Unit. In all cases, their results were in good agreement with the sample history.

Ceramics, however, have a long and stable lifespan.

"If you go to a site and you find large amounts of Roman pottery, then you know you've got a Roman site," says Richard Evershed, Ph.

Archaeologists have unearthed the oldest known pottery from Papua New Guinea in a surprisingly remote location in the rugged highlands.

"A lot of Egyptian mummies were exported out of Egypt by the Victorians, and they often applied modern treatments to preserve them," Evershed says.
