How Dalí’s Amber Varnish May Have Caused This Painting to Decay

A new scientific study has revealed the cause of deterioration in Salvador Dalí's 1946 painting 'The Temptation of Saint Anthony.' Researchers from the Royal Museums of Fine Arts of Belgium and an international team used advanced imaging techniques to determine that the degradation, which includes areas becoming transparent or textured, is linked to the chemical interaction between a zinc white paint layer and an amber varnish layer, both materials specifically advocated by Dalí in his own artistic manual.
