Conservation of varnished map

  • Owner: Private collection
  • Artefact: Map of Catalonia, oversized (164 x 136 cm, wooden slats excluded). Drawn on China ink, hand coloured with watercolour, gouache and coloured pencils. It was lined on a canvas and varnished.
  • AuthorHermanos [Mari]stas (Marist Brothers, catholic teaching congregation).
  • Date: 1906.
  • Damages: [3rd video below, left image] The wooden slats (top and bottom) and fabric tapes on the edges were lost, although there was evidence of their former presence. General dust and surface grim, stains, remnants of synthetic glue applied on surface. Tears and losses on both the lining and the paper. Surface cracks on the varnish, wrinkles and folds.
  • Conservation treatment: Dry cleaning, removal of former restorations (synthetic glue), [1st video below:] varnish removal with gels. [2nd video below:] fabric lining removal, capillary washing. Reinforcement: infilling losses, backing with Japanese tissue, lining with new cotton fabric. Retouch (losses), varnishing, new fabric tapes on edges, new wooden slats on top and bottom.
    You can see all these stages in the videos below. The second has episodes that you can get right into by opening the video on YouTube.
  • Conservartors: Tereza Kubalová, Cristina la Chica, Rita Udina.
