In this study, the possibility of radiocarbon dating lead white pigments alone and in oil paints was explored using well-dated lead white pigments and paints. This study thus proposes new strategies for 14C dating of artworks.ĪB - Lead white is a man-made white pigment commonly used in works of art. A single lead white paint sample can yield two distinct radiocarbon ages, one from the carbonate and one from the natural organic binder. Additionally, a two-step method was developed to allow 14C analysis of both the lead white pigment and oil binder from the same sample. We hereby show that the lead white pigment can be dated by 14C and used as proxy for the time of creation of an artwork. The method was applied to two case studies, where lead carbonate samples were dated in two oil paintings, one Baroque and one from the 20th century. Resulting 14C ages on lead white pigments produced following the traditional stack process, where carbonate groups results from the incorporation of CO2 originating from fermentation, matched the production years, while radiocarbon dating of lead white made using other industrial processes indicate that 14C depleted CO2 was used in their production.
