Detail

 

The project examines the deterioration of cadmium sulphide yellow pigments used in artists paints. The investigation included identification of the pigment in paintings, including works by George Seurat and Vincent van Gogh, and associated colour and surface changes in the paintings.

 

This is combined with an experimental study of historical and modern examples of the pigment, prepared in a range of binding media, and artificial aged to characterise the changes that may occur on ageing.

The images below show Scanning Electron Microscopy (SEM) images of these deteriorated pigments.
