Due to main renovation works, the Van
Gogh Museum in Amsterdam is temporarily hosted by the Hermitage Museum, where
it will remain until 25 April 2013.
The Van Gogh Museum has been
involved over the last 15 years in researches about the life and work of Vincent
van Gogh, in particular, starting from 2005, in collaboration with Shell and
the Netherlands Institute for Cultural Heritage, a scientific research project
is in course, entitled “Van Gogh's studio
practice”. The aim is to deeply investigate the work of the artist and understand
how his art was related to that of his contemporaries, extending the research
also to artists with whom he came into contact like Mauve, Toulouse-Lautrec,
Signac and Gauguin or of whose art he well acquainted the working like
Monticelli, Delacroix and Millet.
The project should be ended within
Spring 2013, that is in coincidence with the re-opening of the Museum.
Waiting for visiting the Museum again,
let’s have a look to its website, in order to know the techniques that are
being used for the on-going investigations and the results obtained up to now.
From the preliminary report
concerning the employed methods, it seems that the observation of paintings
through normal, raking and transmitted light is the first necessary approach
for their knowledge. Soon after it comes UV fluorescence to detect the
different varnish layers, then the infrared reflectography which allows to
reveal the presence of preparatory drawings, like the guidelines for
perspective seen in “Paris from Theo’s
apartment in Rue Lepic”, X-radiography, that permitted to detect, turned of
90 degrees, a human figure, perhaps referable to “Sewing woman”, underneath the painting “Basket of potatoes”, and optical microscopy also with polarized
light to study the shape of brushwork. Thanks to micro-samplings (fragments of
paint not larger than a pin point or micrometric stratigraphic sections), it is
also possible to carry out scanning electron microscopy with energy dispersive X-rays
spectroscopy (SEM-EDX) and transmitting electron microscopy (TEM) investigations. These provide the chemical analyses of painting
and preparatory layers, such as that of “Banks
of the Seine” in pure lead white and not mixed with cheaper fillers like in
more commercial paintings. To prepare the samples for TEM, a highly
sophisticated instrumentation was used: a nano-machining with the focused ion
beam (FIB).
For the moment we can admire the paintings
at the Hermitage, waiting for the Symposium that will take place in Amsterdam from
24 to 26 June 2013 and with which the period of the results communication will finally
start.
