Carbon-14 dating method
Carbon-14 dating [aka Radiocarbon dating] is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
Following the request for authentication by several buyers of paintings presented to them as authentic works of T'ang Haywen, and because a number of these paintings presented serious flaws, T'ang Haywen Archives has decided, in a first step, to proceed with the Carbon-14 dating for a total 20 paintings in order to prove the date of execution scientifically.
All these paintings are diptychs, ink and/or watercolours, executed on Arches paper, therefore in principal belonging to the final period of the oeuvre of T'ang.
The task of dating the works was entrusted to the Laboratory of Ion Beam Physics of the Swiss Federal Institute of Technology in Zurich, Switzerland, also known as ETH University.
