Preventive Conservation: implies an
indirect action taken to guarantee that the environmental
conditions on which the objects are conserved, (humidity,
temperature, illumination, but also handling, security, etc.)
are the best possible. This approach considers that the
dammage produced by different agents (both internal and
exterrnal) is unavoidable, but can be minimised in order to
extend the lifespan of the cultural property.
Interventive Conservation: an action
to be taken directly on the objects, once the dammage has been
produced and in order to slow it down as much as possible (to
stop it is not possible).
Restoration: implies a much more
extensive action taken upon the pieces, with the idea of
getting them back to their original condition. Restauration
requires a reconstructive action. Nowadays restauration is a
controversial concept, beacuse every intervention is supposed
to be reversible and easy to identify.
The Astronomical Museum carries out continuous programs of conservation and takes actions directed
towards preventive conservation of its heritage. The programs
of digital scanning and digital photo held at the Museum
should also be considered as acts of conservation.
