The ornamental plaster work surrounding the four
magnificent murals by Oliver Dennett Grover is
toned to give a very subtle rubbed patina.
There are four different areas of original toning.
There are medium dark green rectangles on the
spandrel panels. There are two different examples
of a greenish/beige toning on most of the flat
banding that varies in darkness and thickness.
All of the foliage and relief panels have been coated
with a gray/beige layer that has been rubbed off all
of the highlights.
The gilt highlights were oil gilded using a bright
yellow toned size applied to the sculptural
highlights with a brush. The leaf appeared to be
gold, not composition leaf, due to the fact of no
examples of copper alloy oxidation and no
appearance of a protective coating. The gilt has
the warmth and brightness of reflection consistent
with 23Kt gold.
CONDITION
The plaster work was extremely dirty with loose
dust and debris, and accumulated grime.
There was an area of missing plaster due to
water leak.
TREATMENT
All necessary cleaning was performed; the missing
plaster area was filled in and painted to match the
original coating. Gold leaf was applied in
damaged areas.
