Prior to treatment, samples were taken from the ceiling for laboratory analysis. Once the nature and source of the efflorescence was identified, it was removed from historic surfaces using appropriate methods/materials and localised flaking paint was consolidated.

During the project a number of unexpected discoveries were made which have contributed to our understanding of the building’s history:

  • the re-use and overpainting of previously decorated timbers;
  • historic alteration of the decorative design and colour scheme of Bishop Gavin Dunbar’s heraldic shield.

An extremely vulnerable, surviving fragment of early frieze plaster with paint remains was stabilised using a nanolime product designed specifically for conservation.
