Conservation of choir book, an oversized manuscript on parchment

CASTELLANOCATALÀ

  • Owner: Alcon-Cusí Museum (Royal Academy of Pharmacy of Catalonia).
  • Object: Choir book, an oversized manuscript on parchment. The bookbinding is full leather on wooden boards with brass edges, as well as clasps, also in brass. There was a contemporary bookmark made with green laced bands preserved with the binding.
  • Date: 1634, renaissance style.
  • Damages:  The wooden boards have woodworm damages and there were losses on the parchment folios due to iron gall ink. Oxidation of metal elements (locks, brass edge, nails…), the clasps were loose and one of them missing (back part of the lower one). Presence of synthetic adhesives applied in former treatments.
  • Conservation treatment: Removal of synthetic adhesives which were damaging the leather, rather than reparing it. Conservation of the leather, repair of broken clasps and reproduction of the missing parts. Consolidation of parchment losses.
  • Conservators: Kristiina Moosel, Clàudia Callau, Rita Udina
  • Photographs of the “after” treatment (header and right side of images): Pep Soler.
