Absolute dating of mortars is crucial when trying to pin down
construction phases of archaeological sites and historic stone buildings
to a certain point in time or to confirm, but possibly also challenge,
existing chronologies. To evaluate various sample preparation methods
for radiocarbon (14C) dating of mortars as well as to compare different dating methods, i.e. 14C
and optically stimulated luminescence (OSL), a mortar dating
intercomparison study (MODIS) was set up, exploring existing limits and
needs for further research. Four mortar samples were selected and
distributed among the participating laboratories: one of which was
expected not to present any problem related to the sample preparation
methodologies for anthropogenic lime extraction, whereas all others
addressed specific known sample preparation issues. Data obtained from
the various mortar dating approaches are evaluated relative to the
historical framework of the mortar samples and any deviation observed is
contextualized to the composition and specific mineralogy of the
sampled material.
