The art detectives
Emma Stoye finds out how spectroscopic techniques allow scientists to look over the shoulders of old masters
The scientific scrutiny of art dates back hundreds of years. Accounts from as early as the 16th century describe collectors grinding up and analysing the creations of painters and sculptors – sometimes for restoration, but often just out of interest. Most of the techniques now used have been borrowed and adapted from other fields – x-rays, for example, were used on paintings shortly after they were developed for medical imaging.
Nowadays, the main challenge is to investigate without causing damage. There is unfortunately no silver bullet for this, and different pieces require different techniques because of the vast range of materials used to make paints. There may be limitations, but art historians are increasingly recognising the value that science can bring.
Emma Stoye meets with the art detectives, using science to discover the secret history of paintings.
