instruments produced in Cremona (Italy) during the
17th and 18th century have been considered. Both noninvasive
and micro-invasive instrumental techniques
were carried on to directly highlight the treatments
employed on the wood before varnishing. Scanning
Electron Microscopy performed on cross sections
highlights the presence of two different methods of
wood treatment, in order to inhibit the penetration of
the varnish into the porous structures. In one set of
fragments, the wood was treated with a filler made
with gypsum dispersed in an organic medium. A
mechanical treatment or a digestion of the wood
structures with a basic solution, which caused a
collapse of superficial tracheary elements, was
employed on the other fragments
