From: Unexpected presence of 14C in inorganic pigment for an absolute dating of paintings
Consistency of the calibrated ages for lead white samples from the wall paintings at Château de Germolles, Burgundy, France. Calibrated radiocarbon dates of lead white-based paints are represented in grey and the statistical combination of the three dates in blue (1297–1400 AD). A χ² test value of T = 2.1 (5% 6.0) shows the consistency of the dates. The yellow line represents the expected date (1388–1390).
