New ceramic dating process unearthed By Lewis Brindley20 May No comments By measuring moisture recombination in ceramics, scientists have found a new way to date ancient pottery and brickwork A new way to find the age of ceramic objects, such as ancient pottery, has been developed by scientists in the UK. The technique measures how much water the items have absorbed since they were fired – simply and accurately revealing when they were made.

Broken pottery, brickwork or tiles are unearthed at almost every archaeological dig site, but they are often of little use to archaeologists as determining how old they are is difficult. Carbon dating cannot be used because ceramics are made from finely-grained mineral clay, and alternative dating methods are complex and costly. Now, UK scientists have found a way to date these artefacts and thus give fresh insight into the history and construction of excavated ruins or items.

The laboratory procedure is simple: Then, because mineral clay composition can vary wildly between different ceramics, the sample is monitored to determine the rate at which it picks up water – allowing the age to be calculated. The researchers indicate that the technique may also find uses in spotting fake objects or uncovering whether buildings have been re-built or experienced a fire.

For example, while testing a variety of bricks and tiles provided by the Museum of London – including Roman, medieval and modern samples – all but one of the samples were accurately dated. The sample that threw the results was a clay brick from a medieval priory in Canterbury, UK, which was dated at only 66 years old instead of several hundred.
