New methods or dating archaeology
But, for a single culture site the method is quite reliable.Quite convincing dates are sometimes arrived at by importing parallels from other contemporaneous cultures.Using the time law, it is possible to extrapolate the information collected to calculate the time it will take to regain the mass lost on heating – revealing the sample's age.Lead author Dr Moira Wilson, Senior Lecturer in the School of Mechanical, Aerospace and Civil Engineering (MACE), said: "These findings come after many years of hard work.But new research shows that commonly accepted radiocarbon dating standards ...An exceptional collection of bronze weapons dating from the Iron Age II (900-600 BC) has been uncovered near Adam, in the Sultanate of Oman.
Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.
We are extremely excited by the potential of this new technique, which could become an established way of determining the age of ceramic artefacts of archaeological interest.
"The method could also be turned on its head and used to establish the mean temperature of a material over its lifetime, if a precise date of firing were known.
The technique involves measuring the mass of a sample of ceramic and then heating it to around 500 degrees Celsius in a furnace, which removes the water.
The sample is then monitored in a super-accurate measuring device known as a microbalance, to determine the precise rate at which the ceramic will combine with water over time.
