It is a conservation technique intended to provide a structural support of the photograph after removing a poor quality mount.
- Polyester (Dacron)
- Filtered water
- Mylar (melinex polyester)
- Wheat starch paste
- Two Japanese brushes (one for applying the starch paste and one for flattening)
- Two pieces of western paper: one Mirage (for support) and one library Bristol board (for aesthetic purposes)
How to do:
- Apply wheat starch paste on plexiglas surface and cover it with a sheet of wet polyester (Dacron).
- Brush wheat starch paste all over the Dacron, put a damp sheet of Mirage paper on it and apply wheat starch paste.
- Put the piece of Bristol board on top of the coated Mirage paper.
- Aside, place the photograph on a separate piece of mylar with the face down and humidify it from both sides.
- Apply wheat starch paste all over the back of the photograph.
- Place it on the Bristol board and remove the mylar by rolling it.
- Wipe the surface of the photograph in order to remove the excess water and leave it to dry for few days.
- Remove the photograph from the plexiglas and polyester mechanically. Trim it with scalpel.
- For this type of lining the wheat starch paste should be thinner than mending paste.
- Use blender for preparation of the paste because it helps to make it smoother.
- You can use any other paper with smooth surface.

It is a conservation technique intended to secure emulsion that is in danger of detaching.
- 1% of gelatin
- Coffee warmer
- Filtered water (to humidify the photograph)
- Warm press
- Release paper (put in the warm pres)
How to do
- Warm up 1% gelatin on coffee warmer until it gets liquid.
- Put the photograph on the clean surface with the recto down so you see verso.
- Spray it twice.
- Aplly the gelatin along the cracks of the photograph by brush.
- Put the photograph with the face down in the warm press for 20 seconds (no more).
- Put it under weight over night.
- 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.
