Engineering Art: Chinese Metal Crafts
The fifth step is polishing, which begins with emery. Polishing aims to even
out the filigree and the filled compartments. The whole piece is again put into
the fire and then polished once more with a whet-stone. Finally, a piece of hard
carbon is used to polish the article a final time to obtain some luster on the
surface.
The sixth step is gilding, which is done by placing the article in gold or
silver fluid, charged with an electric current. The exposed parts of the
filigree and the metal fringes of the article will again undergo another
electroplating and a slight polishing.
Filigree inlays
Filigree inlays, also called "refined metal crafts", are
made of gold, silver and other materials inlaid with various kinds of precious
stones, pearls, or woven patterns. They fall into two categories: filigree,
where gold and silver are made into thin threads and then transformed into
craftworks using such techniques as piling and weaving; and inlays, where thin
gold and silver strips are hammered into wares, carved with decorative patterns
and then inlayed with precious stones.
Filigree inlays took shape as early as in the Spring
and Autumn Period (770-476BC), achieved super craftsmanship in the Ming
Dynasty and enjoyed great developments in the Qing Dynasty. As a result, many
famous filigree inlay works have continued to emerge, many becoming articles of
tribute for the imperial courts.
The craft of filigree inlays is the most famous in Beijing and Chengdu,
capital of Southwest China's Sichuan
Province. Filigree inlay works in Beijing feature weaving and piling, and
dian cui, which refers to pasting blue and green leathers of kingfishers onto
gold and silver wares for a better effect. Beijing filigree inlay craftworks
were awarded the Excellent Design Award at a Southeast Asian jewelry design
contest.
