The GCI's Scientific Program is collaborating with the Swedish
Corrosion Institute in Stockholm to address some of the issues relating
to corrosion of copper alloy surface coatings such as brass on metallic
substrates. As part of the research, the GCI has established a testing
station within the J. Paul Getty Museum grounds in Malibu, where
metallic coupons, of internationally approved dimensions, are exposed
to the ambient environment.
The research project was instigated in an effort to evaluate metallic
substrates and organic coatings that could be used in the restoration
and conservation of the Constantin Brancusi sculpture The Infinite
Column. The sculpture, erected in the 1930s in Tirgu-Jiu, Romania,
is one of the most famous examples of Brancusi's work and forms
part of a unique assemblage of outdoor sculptures in Tirgu-Jiu that
includes The Table of Silence and The Gate of Kisses.
The results of the collaborative research will enable the GCI to
provide advice to the Romanian authorities who are planning to dismantle
the sculpture for inspection and conservation.
Brancusi coated the sculpture with a thermally sprayed brass finish
that corroded badly, and the sculpture now suffers from deterioration
of this coating, corrosion of the underlying cast iron panels, deterioration
of the internal steel support structure, and failure of the old
organic protective coating applied to the outer surface. The principal
aim of the restoration process planned by the authorities will be
to maintain the artistic integrity of the structure while restoring
it to an appearance in keeping with the artist's original aesthetic.
