Cloisonné is a famous traditional enamelware
with a history of over 500 years. Cloisonné is one of the famous
arts and crafts of Beijing. The making of cloisonné requires rather
elaborate and complicated processes: base-hammering, copper-strip
inlay, soldering, enamel-filling, enamel-firing, polishing and
gilding. Base-hammering of body is the first step in the making of
cloisonné. The material used for making the body is copper, because
copper is easily hammered and stretched. This step requires a sound
judgment in the shaping and uniformity of thickness and weight. It
is in fact the work of the copper-smith. The only difference is that
when an article is shaped, the copper-smith's work is finished,
whereas the cloisonné craftsman's work has just begun. The second
step is filigree soldering. This step requires great care and high
creativeness. The artisan adheres copper strips onto the body. These
strips are of 1/16 inch in diameter and of lengths as the artisan
desires. The strips of filigree thus adhered make up a complicated
but complete pattern. The artisan has a blueprint in mind and he can
make full use of his experience, imagination and aesthetic view in
setting the copper strips on the body. The third step is to apply
color which is known as enamel filling. The color or enamel is like
the glaze on ceramics. It is called falang. Its basic elements are
boric acid, saltpeter and alkaline. Owing to the difference in the
minerals added, the color differs accordingly. Usually one with much
iron will turn gray, with uranium, yellow, with chromium, green,
with zinc, white, with bronze, blue, with gold or iodine, red. The
colors are ground into minute powder and applied in the cells
separated by filigree. The fourth step is enamel firing. This is
done by putting the article, with its enamel filling, into a kiln.
After a short moment, the copper body will turn red. But after
firing, the enamel in the little compartments will sink down a bit.
That will require a re-filling. This process will go on repeatedly
until the little cells are filled. The fifth step is polishing. The
first polish is with emery. Its aim is to make the filigree and the
filled compartments even. The whole piece is again put to fire, then
polished once more with a whet-stone. Finally, a piece of hard
carbon is used to polish again so as to obtain some luster on the
surface of the article. The sixth step is gilding. This is done by
placing the article in fluid of gold or silver, changed with
electric current. The exposed parts of the filigree and the metal
fringes of the article will again undergo another electroplating and
a slight polish. |
