Monitoring of the surface appearance of daguerreotypes during their first tarnishing, electrolytic cleaning and possible re-tarnishing after treatment

Host Institution: UVA

Objectives

Application of imaging techniques to assess the surface modification of daguerreotypes during their alteration and further restoration using controlled electrolytic processes:

  • Development of a monitoring protocol for tarnishing process using imaging techniques.
  • Definition of the conditions for a controlled electrolytic removal of the tarnishing.
  • Use of the monitoring protocol to assess cleaning process and further reactivity of a metal surface.
  • Application on real daguerreotypes and optimization according to the nature of tarnishing and the conservation condition of the artifacts.
