Techniques for analysis of art pigments

Popis výsledku v původním jazyce

In our forensic practice, we come across case studies that are focused on recognizing whether it is an original art object or a forgery. Especialy in art paintings, as a basic technique, we use radiographic methods - that is, X-ray. This method will already help us when comparing the questionable work with possible originals by the author, and will also indicate whether it is the author's painting technique, or whether a technique is used, e.g. pre-drawing and then filling in, which the author does not use, etc. It is very easy to detect repaintings . Also, high radiographic contrast can inform us about the pigments used. Analysis of pigments is an important part of forensic expertise for evaluation of authenticity of artworks. Identification is based on similarities or differences in composition between materials detected in questioned artwork and samples or information in databases of originals from authors. For non-destructive analyses, we mainly use mobile technicians - be it Infrared spectrometers or Raman spectrometers. Modern pigments and other materials are mostly prepared for commercial sale and are easy using.We know acording ou analysis, we can find big differences both in the trace materials that these pigments contain (they carry them from current production) and pigments structure that were used. We focused in cooperation of Nationale Gallery Prague on the first half of the 20th century.
