OD-XAS (300 K) of archaeological black-gloss pottery over the Ca L2,3 edges, for samples with different Ca content. Curves (i) and (ii) are from the gloss, where the CaO concentrations are 0.55 and 1.20 wt%, respectively. Curve (iii) is from the ceramic body whose CaO content is 11.3 wt%. Inset top left: the simulated excitation spectra (normalized) for a range of values of the concentration parameter over an order of magnitude. Inset bottom left: emission spectrum from the ceramic body: this is dominated by the emission of Mn2+.
