Oil paint
In 2011 Burnstock was member of a team that confirmed in the BBC One television series "Fake or Fortune?" that the painting "The Procuress" in the Courtauld's collection – a version of a 1622 work by Dirck van Baburen now in the Museum of Fine Arts, Boston – is an Oil paint-Bakelite forgery by Han van Meegeren made in the 30s or 40s of the 20th century.
