7 ARCHAEOMETRIC ANALYSIS OF ARCHAEOLOGICAL MORTARS AND PLASTERS FROM KYME (TURKEY) Introduction Domenico MIRIELLO* Andrea BLOISE Gino M. CRISCI Carmine APOLLARO Luca CARACCIOLO Antonio LA MARCA Mortars and plasters, which are mixtures obtained by mixing a binder, water and sand in suitable proportions are used to bond diverse types of stone materials or bricks in ancient and modern masonry 1. Because they are artificial materials, mortars have diverse compositional and material characteristics, as a result of different construction needs and the technological knowledge of the workers who produced them. Recent reports have shown that mortars * Domenico MIRIELLO: assistant professor of Analytical methods applied to stone materials to the course of Science and Techniques for the Conservation and Restoration of Cultural Heritage at the University of Calabria (Italy), tel ; miriello@unical.it.

8 are excellent sources for identifying the provenance of materials used in historical edifices and for information on the construction history of specific monuments 2. Mortars in particular have always attracted the attention of many scientists. The historical and archaeological importance of mortar can only be understood if we consider some of the most important monuments in the world, such as the Colosseum, the Great Wall of China, the Leaning Tower of Pisa, or great cities of antiquity like Troy, Mycenae and Rome. Without mortar, it is probable that neither the Colosseum or many of the splendid Pre- Aztec cities of Mexico could have lasted until now 3. This lecture summarizes the results of archaeometric analysis performed of Roman, proto Byzantine and Medieval mortars, sampled in the archaeological site of Kyme (Turkey), an Aeolian city, founded in the middle of the XI century BC by Greek populations. The present study, which is part of a wider project, aims to supply the first compositional data on the mortars of the archaeological area of Kyme, and to highlight the chemical, petrographic and mineralogical differences between the Roman, Proto-Byzantine and Medieval mortars. Some of these results have been recently published by our scientific team 4. Sampling and Analytical Techniques One plaster and eight mortars were sampled from the archaeological area of Kyme (Fig. 1) and they were marked with the following abbreviations: M1, M3, M4, M5, M6, M7, M8 and Kmo. 2 Miriello D., Barca D., Bloise A., Ciarallo A., Crisci G.

9 The samples were studied in thin section by polarised light microscopy with a Zeiss petrographic microscope, and analysed by XRF (X-Ray Fluorescence) on pressed pellets to determine the chemical composition of major elements, on a Bruker S8 Tiger WD X-ray fluorescence spectrometer. The binder (size<1/16 mm) of the samples, volcanic aggregates and lime lumps were also analysed on polished thin sections to determine major chemical composition by SEM-EDS microanalysis on a FEI Quanta 200 instrument, equipped with an EDAX Si (Li detector). To better point out the similarities and the geochemical differences of the binder of the mortars, we calculated the hydraulicity index (H.I.) in agreement with Boynton 5. The mineralogical composition of the samples was studied using a Bruker D8 Advance XRD Diffractometer operating at 40 kv and 40 ma, Cu Kα radiation monochromated with a graphite sample monochromator. Scans were collected on powder samples in the range θ using a step interval of θ, with a step-counting time of 3 seconds. A semi-quantitative estimate of the aggregate/binder ratio and macroporosity was obtained by comparing the thin sections observed by optical microscopy with charts to aid visual estimation of modal proportions of minerals in rocks 6. The calcium carbonate content was determined by De Astis calcimeter. Summary of the Results - M1 and M6 are chemically and petrographically similar. The historical attribution of sample M6, belonging to the Roman-Imperial period, allows us to locate sample M1 to the same period. As regards the mortars sampled on the proto-byzantine floor, M2 and M5 samples, are both cocciopesto mortars. They are compositionally similar, while sample M4, another mortar sampled from the proto-byzantine floor, has no cocciopesto (Fig. 2). 5 Bonyton R.S., Chemistry and technology of lime and limestone.

10 - Another important result concerns M3 sample. Among all the mortars, M3 (sampled on the wall of the Medieval castle) is definitely the sample with the worst technological features. As a matter of fact, the sample, which is particularly friable, is made of a mixture of clay, lime and aggregate; thus denoting a loss of technological knowledge compared to the mortars prepared in previous historical periods. - Marble powder artificially added to the mixture was found in sample Kmo (Fig. 3). This procedure was particularly appreciated by Roman workers, who wanted the plaster to have a marble brightness 7. - As concerns provenance studies, heulandite and echinoid spine traces found in some sample, may be used in the future to determine the provenance of the aggregate. - It is useful to point out how, among the Roman mortars in Kyme, the use of natural pozzolanas can be excluded. As a matter of fact, the Romans used to abundantly use pozzolanas in mixtures mainly in bedding mortars. This practice could be justified by the difficulty of finding natural pozzolanas in the area, rather than cocciopesto. This hypothesis, however, needs to be verified in future studies mainly focusing on the provenance of raw materials used to prepare mortars. - Moreover, Romans in Kyme used inert material coming from old constructions, as an aggregate in the new mortarsas suggested by the occurrence of recycled mortar fragments in sample M8 (Fig. 4). - Concerning lime typology, the analysis on binder pointed out that natural slaked lime was used in Kyme, but, to increase mortars performance, the lime was made hydraulic by adding cocciopesto to the mixture. - Thanks to the present study, the first compositional data concerning the mortars in the archaeological area of Kyme were produced.
