Bomb 14C on paper and detection of the Forged Paintings of T’ang Haywen

The bomb-peak signal preserved in the Arches® cotton paper was used to detect art forgeries imitating the work of Chinese artist T’ang Haywen (1927–1991). The dating of seven legitimate T’ang Haywen art pieces showed that the timing of the paper production was consistent with the artist’s use of Arches® paper starting in the early 1980s. The measured F14C of the paper from the 14 suspected forged paintings shows that the support material was produced in the last decade (2008–2011), therefore the art pieces could not be genuine T’ang Haywen works.
