Consolidation

It is a conservation technique intended to secure emulsion that is in danger of detaching.

You need:
  • 1% of gelatin
  • Coffee warmer
  • Filtered water (to humidify the photograph)
  • Warm press
  • Brushes
  • Release paper (put in the warm pres)
How to do
  1. Warm up 1% gelatin on coffee warmer until it gets liquid.
  2. Put the photograph on the clean surface with the recto down so you see verso.
  3. Spray it twice.
  4. Aplly the gelatin along the cracks of the photograph by brush.
  5. Put the photograph with the face down in the warm press for 20 seconds (no more).
  6. Put it under weight over night.
Tips:
  • If you don’t have 1% gelatin you can make it by yourself. It is a simple procedure of putting 1 gr. gelatin grains into 100 ml. filtered water. The gelatin will swell as it absorbs the water. If we keep it in refrigerator it can last for 6 months. 

The treatment of the photograph below included: cleaning, mending, filling the losses, consolidation and inpainting.
