The State Research Institute’s for Restoration physic-ochemical laboratory and the Andrei Rublev Museum: years of cooperation

The article discusses the results of long-term cooperation between the Laboratory of Physicochemical Research of The State Research Institute for Restoration and the Andrei Rublev Museum in studying the museum collection. More than 100 icons were examined. More than 10 icons, presumably of the XVI - XVII centuries, were recognized as manufactured in Modern times. Some of the obtained data made it possible to clarify the attribution of the icons of the Moscow collection. The technology of the “Hodegetria” icon of 1480 by the master Dionysius was defined. On the basis of these data, it was proved that the “Assumption” was made in the end of the XV century at the workshop of Dionysius, but by another artist. The artificial posnjakite mineral found in its paint layer served as an aid in attributing the icon “Sergius of Radonezh with the scenes of life” around 1510 to the authorship of Theodosius. The identification of the technological features of the Georgian icon “The Mother of God with the Baby” made it possible to date the icon by the beginning of the XII century. The study of 61 icons of the iconostasis of 1663 - 1670 from the Spaso-Evfimiev Monastery revealed the true color of icons, and it was also proved that the icons of festive row of the iconostasis were painted by Moscow artists in the manner of the Greek masters of the XV - XVII centuries.
