Surface Dirt and dust was removed using dry cleaning methods such as soft brushes and a museum vacuum on low suction with a net guard covering the nozzle.
This was followed by wet cleaning the surface of the pediment with Tri-Ammonium Citrate 2% in distilled water as it was the most affective in removing the engrained dirt and did not affect the state of the oil gilding. Acetone was used to treat the water gilding.

Once the gesso had dried it was then sanded down to make it smooth, level and matched the original appearance of the corner
Conservation of Other Compo Decoration
Gesso and Sanding
The exposed wood was brushed with rabbit skin glue and left to dry before gesso was applied to the wooden surfaces where the compo decoration was missing. The gesso was then sanded down to make smooth and level with the remaining compo decoration.
Moulds and Casting
-Vinamould (yellow) is a wax used to create the mould of the original compo decoration.
-Clay is used to build up walls around the selected decoration to prevent the Vinamould from spilling out while it sets
-Once set the Vinamould is removed to reveal the detail it has picked up from the frame
Application of the new compo decoration
-Warm compo is then pressed into the vinamould and carefully removed
-The compo is left to set for a day until firm before it is cut to the size and shape of the missing decoration on the frame
-Once cut the compo is then placed on top of the hot ceramic tile which sits over a pan of boiling water. This allows the compo is become more flexible and will allow it to attach itself with the gesso it will sit on
