e (1947: 10) writes, “in the field paraffin wax is often used to strengthen bones … in some cases the wax was put on too hot and penetrated so deeply that it could only be removed with difficulty”; she concludes “it is best to avoid the use of wax for bones, though an exception may be made in the case of paraffin wax bandages”. As conservators, we often find remnants of these treatments, but much more rarely can rely on photographic or written documentation describing the materials used for stabilisation.
The film also documents reconstruction of ceramics recovered at Tell-ed Duweir. In the second sequence, a woman applies thick, dark adhesive to sherds allowing them to dry by propping them up and using gravity to aid tight joins – a technique I and many other conservators continue to use during fieldwork. After the vessel is completely reconstructed and adhesive dried, we see her making plaster fills to fill losses.
Despite not being able to see her face, it is likely that this is Olive Starkey, sister of James and sister-in-law of Marjorie. Olive was responsible for much of the restoration of finds on site and in London and she is directly thanked by Olga and colleagues for her work in the “repair and reconstruction of pottery since 1933” (Tufnell et al. 1940: 12). This practice was not uncommon; many wives and other female relations of archaeologists worked at “mending”, “sticking” and “restoring” artefacts in the field during this early period. The IoA hired Olive Starkey to work in the Repair Department in December 1945. In this capacity, she and Gedye taught students how to conserve recently excavated artefacts from Tell-ed Duweir as well as other sites.
The animation is followed by a clip of Ione Gedye herself demonstrating this technique on iron artefacts in the laboratory. Critically, students are advised to control the treatment process by monitoring the presence of chlorides in soak water.
Work is conducted in an open laboratory and without personal protective equipment such as gloves. As with the Lachish films, health and safety in the handling of chemicals is not a priority. While some steps utilise harsher chemicals and tools than we may use now, the approach as demonstrated is not very different from electrolytic methods used to treat metals today.
Professional photographer Maurice Cookson, former director of the IoA Photographic Department and author of the ground-breaking Photography for Archaeologists (1954), and Sheppard Frere, Professor of Archaeology of the Roman Empire at University of London created the film “Lifting a Mosaic Pavement” in 1957 to document the removal of an in situ mosaic and its subsequent treatment. The mosaic was recovered in Building 3 of Insula XXVII at Verulamium, a Roman site in St. Albans, Hertfordshire.
The film is interesting in that it documents the reflexive practice of conservation where process is assessed in real time and modified to better influence results. This is clear in the titles state that the use of solvent in removing the PVC adhesive was not as successful as removal without solvent.
We are fortunate that the mosaic lifting and backing procedure is further described in publication (Frere 1958) with specific information regarding the intervention materials using the lifting and backing processes including cement mortar recipes.
As Frere states (158: 116), discovery of the mosaic offered those involved the opportunity to develop a new method in collaboration with chemists working in industry. Treatments of this type are very destructive, and not as commonly utilised, but remain attractive to archaeologists interested in recovering coins and pottery in order to date the mosaic, as well as stratigraphic layers from earlier occupations.
However, the technique continues to have a place in salvage and rescue archaeology. For example, conservators and archaeologists used a similar approach (though with more stable conservation materials) to recover numerous Roman mosaics from Zeugma, located near Gaziantepe, Turkey, following the construction of the Birecik Dam on t
