Treatment

• Photographic documentation of the painting and frame.
• Surface cleaning and separation of the canvas from the stretcher.
• Consolidation of the paint layer.
• Cleaning and treatment of the frame and the support.
• Securing the canvas to a new stretcher.
• Chemical and mechanical cleaning of the paint layer to remove accumulated dirt from the passage of time and oxidized varnish.
• Leveling of the ground layer.
• Chromatic reintegration, using mimetic technique in small areas and rigatino in large gaps. This technique allows establishing a distinction between the restored areas and the
  original paint.
• Application of a thin layer of isolating varnish.
