Over the last few decades, carbon-14 dating has regularly been used to authenticate art objects, and has proved its worth as a tool for identifying fakes made from modern materials.
Faced with the constant refinement of forgery techniques however, this method has its limitations, and a constant dialogue has to be kept up between scientists and art-world experts.
Following questions posed by certain problematic objects, some erroneous ideas began to circulate, and a number of false underlying assumptions came to light. Emmanuel Vartanian and Céline Roque will confront these with scientific fact and unveil some new advances that enable them to be overcome.
