New methods of examination of paintings
 

some time ago at the forum addressed the topic of new methods of examination zhivopisi.diskussiya was partly due to the transfer of "School for Scandal with Andrew Sarabyanovym (he mentions this method is about 28 minutes transfer) http://rutube.ru/tracks/1503479 . html . article published on the website is well described by the general principles of this method http://artinvestment.ru/news/artnews...orgeries.html. It seems that the following document gives a detailed presentation bolle about it.

proper document

Old picture can be lacquered later production, which contains mentioned isotopes. It happens that pozhuzhshie painting smeared with linseed oil. Oil or varnish, is not yet hardened, can penetrate into the pores of the paint layer and distort the isotopic composition of this layer and, consequently, the results of the analysis. So this method of examination is not reliable at 100%.

Do you think someone is left linseed oil to 45 of release, to make frank fabrications? By this method of analysis of age should be treated only as one of the complex technological expertise to determine the age. And he answered only one question: "is present in a colorful layer of linseed oil before or after 1945.?" If the isotope is not, then the answer is obvious. And if there are, further examination must technically justify their existence. They invented a new method and the experts should take him to the arms during the technological expertise.

Coglasen with you. Moreover, outside of this technique is the entire corpus of works written in tempera and gouache, which are binding in gum arabic, casein glue, gum, egg yolk, etc., depending on the recipe.

In fact, by and large, it is not even the method of examination of painting, and perhaps one of the many methods for the study of the paint layer (and even early-binder, in this case, lipid) and then, very controversial.
Practitioners of experts in laboratory studies, with a smile, listen to such "news."
How many of them already? :)

I also thought about that. This method I learned years and a half ago and immediately had questions. For example, engaging in restoration, I was at the final stage, to "be invited" grid cracelures work rubbed with linseed oil with Mars transparent, then the surplus naturally tidy. But oil ostaetsya.DRugoy question. The method is correct, as I understood, only in respect of flax. But oil paints are made, including using as a binder poppy, walnut and dr.masel. And as far as I know, this method has not been formally adopted, at least in museums

In-in, we first need to conduct research on the identification of the binder, microchemical analysis, and only then the presence of radiation, if the connecting-linseed oil?

Cyril! Recently I read on computer forensics! Its essence is that each artist has his own handwriting, which is not like another. (Type - a handwriting expert) have this expertise already has a name and it is in the final stage (the creation of the program) is very voluminous work of a large number of lyudey.Ssylku to the source I can not say I am in doroge.Sdelayu in later. If anyone is interested? Many of the examination predict a great future.

Of course, very interesno.Vot only immediately arose another consideration. Five years ago I restored a painting by Giovanni Bellini from a private collection in Germanii.Vladelets asked to remove a small record 19 century. when I looked in the binoculars, then grabbed his head, the picture entirely comprised of multi-entries. The most famous example of such work "Last Supper" Leonardo.Seychas probably very few people can tell where there genuine fragmenty.Kak in these cases is the reference base?
