Despite the fact that this research project should be considered as a pilot study, this tends to support the thesis that the lid and the soundboard originate from the same instrument, or at least were painted at a similar period. She placed the sewn canvas over a stretcher and primed it with a white acrylic emulsion gesso, applying the primer in several layers and working over it until it had an extremely smooth finish. Samples from this artefact had been examined before by Fourier transform FT Raman spectroscopy [ 19 ]. Break Point is a large painting comprising sixty-six rows of red text written horizontally on a white background, which collectively describe a car chase. Vermilion HgS was observed in the red areas, whereas orange areas merely contained red lead Pb 3 O 4. During the latter survey the articulating arm was used to allow analysis of a large artefact displayed horizontally.
Non-destructive analysis of museum objects by fibre-optic Raman spectroscopy
View by appointment P The article was first published on 24 Feb J. The data in each section are the characteristic information of the color and topography in sequence. The E1 and E2 data appear to be similar; however, the forgery data were totally different. The intensities of color information at each wavelength were converted from 0 to to decimal numbers, which were measured in the center of each section.

The bifurcated graphs in Fig 5F are the features in region F; however, we were able to differentiate between the original and forgery using the ARs. Most Watched on Vulture. This article focuses on the use of LA-ICP-MS analysis as a new methodological approach for the chemical investigation of black crusts covering the stone surface of monuments and buildings. The advantage of combining two techniques is that the characteristics of the all surface of the paintings about both color and appearance can be observed with this simple system. Investigates the evolution of lead antimonate production during different periods of History, highlighting the different production techniques. Since paper artefacts are fragile, special care has to be taken not to damage them during handling and positioning of the spectrometer.
Working in the gallery also meant that the ambient conditions were far from ideal. In addition there was a large amount of background radiation, both from the gallery lights and from fluorescence, which was probably caused by the varnish layer. Khang's art practice is informed by educational backgrounds in psychology, theology, and dentistry. First , East Asian calligraphy. A high-speed connection is required.
