An innovative approach
Planning and conducting a series of wide-ranging but closely focused
scientific surveys is a prerequisite
for any restoration project to be successful.
The same is true for the step-by-step process of carrying out the
actual restoration, from the simplest to the more complex operations,
moving from one step to the next only after having checked the results
of the previous one.
Basic steps were taken to improve the internal environment (installing
glass screening, substituting incandescent light bulbs, etc) and these
were followed by actions to improve the building itself, and finally
by installing the micro-climatic control unit (CTA), a sort of filter
between the Chapel's interior and the outside, which was the most
innovative feature (one of the first such units in Italy, after the
one for Leonardo da Vinci's Last Supper in Milan).
After the CTA unit had been installed, about a year was spent monitoring
the Chapel's internal environment in order to check the effectiveness
of the operations carried out thus far.
The results were positive, so it was possible to begin the necessary
operations for the conservation and restoration of the Chapel's wall
paintings, halting the extremely serious problem of deterioration
which was causing the plaster and the pigments to crumble away, eventually
leading to the destruction of the frescoes.
