examination timing
I want little to develop this very interesting topic. Experts from the Russian Museum has the highest qualifications in the received data is no doubt - if the analysis showed the presence of paint studied phthalocyanine dye, then before the end of 30-s work can not be dated. At the forum many times wrote that it is desirable to pass the medical examination at least 2 different locations. Also in St. Petersburg, the Hermitage is the specialists of the highest class (including the identification of phthalocyanine in the painting). Just do not know whether (and, most importantly is willing), Mr. Azadovsky there turn. And for 2-3 days to make art history and technological expertise of the two small works really well: having access to a reference database (a Russian museum it is), and using non-destructive methods of analysis, ie without sampling (XRF, IR reflektografiya), all of this equipment in the Russian Museum and there is a sufficiently high level - would wish. As for the dating of the paper, it is the specialists from the Russian Museum were among the first in Russia began research in this area, again using a reference database of the Museum. Publications on this topic is in the public domain - anyone with desire can learn and understand what it gives, then that would not judge whether what just do not know. And yet the article was the phrase literally "Alternative examination indicated wrong museum staff. But if the timing of the examination clearly shows the criteria on which the conclusions were drawn expertise (having the same phthalocyanine), the data on an alternative examination did not - who did it, on what basis they have refuted the conclusions of expert timing, etc. Incidentally, when the 60-ies of watercolors from the collection Azadovsky hit the timing, there was no research methods and instruments that have now. I just know this is a fairly high percentage of work, estimated procurement commissions for museums, marriage on the stage of research. Maybe before bought 30-50 years ago, his hands do not reach.
