Expert conclusion COMPLEX is a full scientific and technological research with a detailed description and report.
The volume of the document starts from 50 pages, including the recorded spectra and tables. Examination allows you to determinate the time of creation of an art object in the range of 25-35 years.
An expert conclusion COMPLEX includes:
- complete visual analysis including microscopic study of an object by dividing the surface in quadrants: a study of texture, features of brushstrokes, shape and type of craquelure in different areas with photographic images, description and preliminary conclusions based on the research findings.
- a detailed analysis in the ultraviolet (UV) range with photo-fixation of the fluorescence of individual pigments, organic dyes and varnishes and their preliminary identification. Isolation of the areas that have been exposed to the restoration and re-writing in order to exclude them from the research process and / or to select them in a separate category.
- full investigation in the infrared (IR) range with dividing the object into quadrants with photo-fixation and detailed description of each area.
- complete X-ray fluorescence (XRF) analysis of ground and paint layer composition (at least 20 samples depending on the size of the object of study) with printing out an enlarged photo, indexing and coordinates of sampling as well as the attachment of XFA spectra for each area with the complete identification and preliminary conclusions.
- full analysis by Fourier transform infrared (ATR-FTIR) allows to determine the type of binder in the paints, organic dyes, coatings and pigments not detected by the XRF analysis the samples were examined, and their complex identification. The table with full results of ATR-FTIR studies is presented in Appendix. The Appendix contains with indexation and coordinates of sampling and the attachment of IR spectra of each sample with the complete identification and preliminary findings.
