X Ray In Marble Conservation

Foreign body ingestion in children is common.

X ray in marble conservation.

Authentication of stone sculpture can focus on materials techniques by which the materials were worked and weathering layers. Thus analysis of x ray images of the body is a valuable medical diagnostic tool. The analyses are conducted by visual inspection chemical analyses x ray diffraction and mercury porazimeter for pore size distribution. The metasomatic reaction between monocalcium phosphate solution and marble substrate was explored to prepare hydroxyapatite film.

Thermal gradients and temperature fluctuations cause high stress particularly in calcitic marbles like carrara marble. The passage of x rays through materials including biological tissue can be recorded. An x ray of the ghent altarpiece painted by jan van eyck in saint bavo cathedral in ghent belgium revealed the structure and details of the large altarpiece s painting scheme. Microfocus x rays synchrotron x ray absorption x ray fluorescence conservation marble glass ship timbers.

The results of the studies and their role in developing conservation strategies are described. In this case the foreign body a marble was too large to exit the pylorus of the stomach. Lytical chemistry to x ray tomography. 2067 533x international journal of conservation science volume 3 issue 3 july september 2012.

Ini tial analyses were performed using the naked eye and a binocular surgical microscope as well as ultraviolet light and x. The prepared hydroxyapatite film was characterized by scanning electron microscopy sem x ray diffraction xrd and energy dispersive x ray edx spectroscopy. Radiographs are often used to identify the foreign body and observe its excretion from the gi tract. X ray electromagnetic radiation of extremely short wavelength and high frequency with wavelengths ranging from about 10 8 to 10 12 metre.

Conservation practices should be directed towards reducing temperature fluctuations. Elemental analyses carried out by instrumental neutron activation x ray fluorescence inductively coupled plasma icp techniques and others often provide the most useful information. The individual grains of marble fig. The complete radiography of the altarpiece was conducted between 2010 and 2011 as part of a project largely funded by the getty institute the x rays and other technical information that was gathered were used to.

I began the research for the second edition in may 2007 as an. It is an overview that maps the landscape of stone conservation cites interesting and representative research and is intended to serve as a useful point of entry to the field.
