Thanks to the laboratory's modern equipment, a painting can be subjected to analysis using infrared reflectography, Wood's light, a stereoscopic microscope, IR spectroscopy and other instrumental techniques.3 e 4 - Microscopic analysis to examine the signs of ageing in the paint layer: the nature of the craquelure (natural or artificial - deep or superficial), the pigments (crystallinity, purity and size), restoration and other factors.Wood's light and monochromatic lights permit an evaluation of the extent to which the painting has been restored, touched up and overpainted, as well as the identification of various fluorescent substances.7, 8 e 9 - Infrared reflectography permits an in-depth examination of the painting bringing to light underdrawings or grids, pentimenti, the depth of the craquelure, and identification of restoration work or the use of different materials.3) with Woods Light and microscope for the examination of restored areas 4) with IR-Reflectography for the examination of the deepest painting layers 5) with microscope, Woods Light and reflectography in order to verify the material uniformity and the ageing of the signature 6) with IR-Spectroscopy for establishing the pigments used and examining the drying of the paint binder attempt to determine the authenticity of a painting must begin with tests and analyses to establish whether the age of the painting and the materials and techniques used are compatible with the presumed date of execution.The Museum laboratorys mission is to improve existing scientific methods and elaborate new methods for the ascertainment of the authenticity of art objects.Ancient DNA used to track the mass exodus of Ancestral Pueblo people from Colorado's Mesa Verde region in the late 13th century indicates many wound up in the Northern Rio Grande area north of Santa Fe, New Mexico, inhabited ...Imagine a rhinoceros-like beast with a sprawling, lizard-like gait and you will picture quite a good portrait of what Moschops looked like.They are certainly among the most fascinating monsters of the South African prehistoric ...
The city's long history, dating back to the Greeks in the eighth century BC, included Byzantine, French, Spanish, and Austrian rule, each of which left its mark.
The ascertainment of the authenticity of this painting has been carried out with scientific tests on the material and through the study of techniques and signs of wear.
In detail: 1) with the spectroscopic dating of the wooden stretcher once proved its originality 2) with stereo microscopic analyses for the study of the painting layer: the drying of the paint binder, the craquelure, the sign left by the stretcher, etc.
However, human beings love to see factual precision, and we want to know how old something is.
Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.
