Radiocarbon Dating Historical Mortars
Lime lumps and bulk mortars show different 14 C contamination when analyzed in several CO 2 fractions isolated from the effervescence of an ongoing hydrolysis reaction. Age profiles of both materials are therefore highly complementary and together they can provide a reliable date. Furthermore, they can also reveal the complexity of the radiocarbon ( 14 C) distribution within the mortar and thus prevent over-interpretation of the data. The lime lu…
Mortar Dating Methodology
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 ( 14 C) dating of mortars as well as to compare different dating methods, i.e. 14 C and optically stimulated luminescence (OSL), a mortar dating intercomparis…
Years of Mortar Dating
Since 1994, our team has gained extensive experience applying accelerator mass spectrometry (AMS) radiocarbon analysis for mortar dating, totaling over 465 samples and 1800+ measured CO 2 fractions. Several samples have been analyzed repeatedly. The research covers both Medieval and Classical archaeology. We therefore believe our experience can be helpful when developing preparation procedures for different kinds of mortars in different areas and…
Successful AMS 14 C Dating of Non-Hydraulic Lime Mortars from the Medieval Churches of the Åland Islands, Finland
Fifteen years of research on accelerator mass spectrometry (AMS) radiocarbon dating of non-hydraulic mortar has now led to the establishment of a chronology for the medieval stone churches of the Åland Islands (Finland), where no contemporary written records could shed light on the first building phases. In contrast to other material for dating, well-preserved mortar is abundantly available from every building stage. We have gathered experience f…
Mortar Dating Using AMS 14 C and Sequential Dissolution
Non-hydraulic mortars contain datable binder carbonate with a direct relation to the time when it was used in a building, but they also contain contaminants that disturb radiocarbon dating attempts. The most relevant contaminants either have a geological provenance and age or they can be related to delayed carbonate formation or devitrification and recrystallization of the mortar. We studied the mortars using cathodoluminescence (CL), mass spectr…
