About Patina
Patina is a
chemical process that alters the surface of a
metal leaving a colored compound adhered to the
metal.
Patinas form on
metal from exposure to the elements, or are
deliberately added by artists and metalworkers.
Patinas may be used to 'antique' objects, as a
part of the design or decoration of art and
furniture.
The most striking
of patinas is a green or blue green surface
created by slow chemical alteration of
copper, producing a basic carbonate. It can
form on pure copper objects as well as alloys
which contain copper, such as bronze or brass.
Patination varies
with the reacted elements and will determine the
color of the patina. Exposure to chlorides leads
to green and blue, while sulfur compounds tend
to brown.
Perhaps the best
known example of patina in the United States is
the bluish-green colored coating on the
Statue of Liberty in New York Harbor, which
is made of copper sheets 3/32 of an inch thick,
roughly the same as two pennies put together,
over an iron framework. The copper has naturally
oxidized to form its familiar patina green
coating.
We apply our own patina compounds in the studio
to create color, texture and pattern, in concert
with our unique ways of realizing using negative
space.
