Advances and limitations of 14C dating in the field of heritage sciences
In heritage sciences, the ability to obtain information about the origin and dating of cultural heritage objects is fundamental for placing an object into its historical context. Radiocarbon (14C) dating can help to identify the period during which a work of art was created by dating its constitutive materials. Such information can, however, only be obtained by removing a sample from the object, which is critical since art is irreplaceable and de…
Selective Dating of Paint Components: Radiocarbon Dating of Lead White Pigment
Lead white is a man-made white pigment commonly used in works of art. In this study, the possibility of radiocarbon dating lead white pigments alone and in oil paints was explored using well-dated lead white pigments and paints. Resulting 14 C ages on lead white pigments produced following the traditional stack process, where carbonate groups results from the incorporation of CO 2 originating from fermentation, matched the production years, while…
Combined 14 C Analysis of Canvas and Organic Binder for Dating a Painting
The use of accelerator mass spectrometry (AMS) for age determinations of paintings is growing due to decreasing sample size requirements. However, as only the support material is usually dated, the validity of the results may be questioned. This work describes a novel sampling and preparation technique for dating the natural organic binder using radiocarbon ( 14 C) AMS. In the particular case of oil paintings, the natural oil used has a high prob…
Investigation of the foil structure and corrosion mechanisms of modern Zwischgold using advanced analysis techniques
Zwischgold is a two-sided metal foil made by adhering a gold leaf over a silver leaf to present a gold surface while using less gold than gold foils. Corroded Zwischgold surfaces appear dark, accompanied by gloss loss and possible mechanical stability issues. Zwischgold applied artefacts are commonly found in museums and churches across Europe and they currently face an uncertain future as conservators have little knowledge to base conservation t…
An XPS study into sulphur speciation in blue and green ultramarine
The lost city of north‐west Queensland: A test of the model of giant Grikeland development in semi‐arid Karst
Jennings and Sweeting's (1963) model of landscape evolution in the Limestone Ranges of Western Australia has been proposed as a general scheme of semi‐arid karstification by Williams (1978) and Ford and Williams (1989). The model involves an initial plateau surface which undergoes progressive karstic dissection. The resultant landscape is characterised first by giant grikelands, then by box valleys and finally by karst towers. The depth of dissec…
