Project Date: December 2009
The design of the new display cases for the paintings by Sebastiano del Piombo is based on a study focused on two main criteria:
- to preserve the paintings within cases that fulfill the role of protecting the works from damage due to both mechanical events and microclimatic variations;
- to respect the exhibition conceived by the architect and museographer Franco Minissi.
The existing cases consist of a metal framework rising from ground level and supported by an element fastened to the floor. The upper parts of the frames are secured to sections fastened to a tubular metal structure fashioned as a groin vault. The paintings are inserted within the frames and secured with brackets and by a 10 cm plexiglass frame.
The concept was to utilize the existing structures and to add outer shell elements made of innovative materials. This gave origin to the “Crystal Boxes,” made of invisible, anti-glare methacrylate and acrylic material.
The same material was utilized to make the “Climaboxes” for twelve drawings by Leonardo da Vinci and for his “Codex on the Flight of Birds” (held by Turin’s Royal Library) for the travelling exhibition in the USA; it was also used for a painting on wood by Beato Angelico (held by the Vatican Museum) for an exhibition in Japan.
The Crystal Boxes are made of an invisible acrylic sheet with white methacrylate edges and are inserted inside the metal structure of the existing frames. The works are mounted following the criteria already adopted in the earlier exhibition. The microclimatic conditions are controlled through miniaturized, high precision data loggers located outside the cases, but fitted with one-meter-long probes. The relative humidity is stabilized with a packet of pre-conditioned ProSorb.
During the coming twelve months, a careful analysis of the temperature and humidity conditions within the cases and in the exhibition rooms will be conducted, in order to assess possible equipment additions.
