The
following history of enameling was written by my good friend and
mentor Craig Ruwe. He worked as an enamel artist for over 30 years
before his passing in 2004. Craig first learned his craft at the
side of Fred Ball in the late 1970's and helped Fred construct
and install a large enamel work called "They Way Home"
on the exterior of the Macy's parking garage in Sacramento.
Craig
taught me what he knew about enameling and encouraged me to explore
and experiment with this ancient media. He is always with me in
my mind and by my side.
Enameling
By Craig Ruwe
Enameling
is one of the oldest arts in history yet one of the least developed
in terms of contemporary usage. Enamel is not paint: it is a thin
coat of glass applied to a metal which, when heated to high temperatures,
melts and becomes fused to the metal in much the same way as ceramic
glazes adhere to pottery. Pure gold, silver and copper are traditionally
the only metals that will work in the enameling process, although
now there are enamels that can be fused to steel, brass and aluminum
as well.
Enameling
was practiced as early as the 5th century B.C. by the ancient
Greeks, and it was the Greeks who developed the most well-known
technique of enameling, cloisonne (literally "to
be cut off from one another" or "compartmentalized"),
in which extremely thin metal wire is applied to a metal surface
and areas between the wire are carefully packed with enamel before
firing. Enamel played an important role in Byzantine art, French
and German art of the middle ages and Renaissance, and Japanese
and Chinese art from the 13th century A.D. to the present. Enameled
pieces grew from the production of tiny jewel-like beads that
were sewn into clothing or placed in sculpture to the magnificent
and elaborate altar-pieces and reliquaries of medieval Europe,
the fine enamel portraiture of the 16th century Limoge, France
and fantastically ornate Chinese cloisonne vases, boxes,
and trays still being produced today.
Many
techniques have been developed over the ages, each giving the
finished piece unique characteristics. These include champleve
(the method of pouring enamel into sunken or gouged areas of metal),
plique-a-jour (a backless wire technique used with transparent
enamels so that the finished piece, held to the light, has a jewel-like,
stained glass window appearance), bassetaille, grisaille
and others.
The
experimental techniques that I use were pioneered and developed
by the late Fred Ball, a California artist who
in the 1960's began using transparent glazes and non-traditional
firing techniques on thin gauge metals. Enamel in its powder form
(made up of silica and lesser parts soda and lime with metal oxides
such as gold, cobalt, manganese, tin, platinum and titanium added
to produce color) is sifted onto the metal and then heated in
a kiln at 1200-1700 degrees F. until the powder melts, fusing
to the metal to produce a thin, glass coated sheath of foil.
The
color and texture of the work can be altered by varying the density
of the application of the powder enamel, by adjusting the temperature
and length of firing time of the firings, and by performing repeated
firings. The kiln used is quite small, and the individual pieces
of copper that make up the completed work are all fired separately
and then laminated together. The final piece is coated with an
acrylic finish to prevent any exposed copper from oxidizing. All
the enamels used are transparent; the unique glowing color quality
of the work is caused by light traveling through the enamel and
reflecting off the polished surface of the underlying copper.
This color will not fade over time even when placed in direct
sunlight, a quality which makes the work unique among framed wall
hangings.
