Reason for treatment
Survey condition, previous treatments and painterly technique.
Consolidate as necessary.
Alter foaming epoxy mount.
Loose paint flakes fragile intonacco and arricio, old plaster of paris mount, discoloured intonacco around surface edge, paint losses
The object had been conserved and re-backed onto Foaming Epoxy in 1999.
The object was thoroughly examined under a microscope. Observations on ancient painterly techniques, past treatments and present treatments were recorded individually as technical information record on hard copy (see envelope for detailed information). A photoshop file detailing the objects condition, observations on painterly technique, past and most current treatment is also available on memory stick.
The object was lightly dry cleaned with low suction vaccuum cleaner.
Loose paint flakes were consoilidated with 12% w/v Primal B60A (acrylic) in deionized water over a layer of Industrial methylated spirits (ethanol,methanol) used as wetting agent. Powdery areas of intonacco were consolidated with several applications of 1.5% Paraloid B72 (ethyl methacrylate copolymer) in Acetone (propan-1-one/dimethyl ketone)/Industrial methylated spirits (ethanol,methanol)(1:1).
The lower and proper right edge of the mount was reduded to 1cm by cutting away the mount mechanically with a hacksaw. This was necessary to enable the painting to be displayed close to the underside of EA 37976(cattle count) and next to EA 37979(owner) in the new gallery. A right-angled stainless steel plate was added to the reduced edges for extra strenght.
