Damascening is the art of inlaying different metals into one another—typically, gold or silver into a darkly oxidized steel background—to produce intricate patterns similar to niello. The English term comes from a perceived resemblance to the rich tapestry patterns of damask silk.
The technique, while also being used on firearms, has a long history in Japan, where it was used to decorate katana fittings, particularly tsuba. Known as zougan (象嵌) in Japanese, it has developed its own subset of terms to describe the particular patterns, although "shippou-zougan" is an enamelling technique which most Westerners would consider closer to champlevé.
The technique of niello is also famously attested in prehistoric Greece. The earliest occurrence of damascening in the Aegean, from the Shaft Graves of Mycenae, dates to the latest Middle Bronze Age/Middle Helladic IIIB period (dagger Nu-304). Ultimately of Near Eastern provenance, the technique of inlaying silver/gold was adapted to suit Aegean taste and style.
Toledo has long been the major European centre, although most modern production is machine made, sometimes on tin rather than steel. Nevertheless, the art has long been practised in Persia, Japan and even China.
Some of these reproductions are "so expertly produced that even knowledgeable Toledeans admit the difficulty of recognizing them as such." However, many shops still offer handcrafted damascened work following the tradition of ancient times, and it is possible to see artisans at work creating these painstaking and time-consuming works of art.
Damascene work has kept to traditional designs with few changes over the years, but there are a few artists who design innovative pieces of jewelry. Because of these reasons the use of this technique has been most popular in Spain.
One of the most important Damascene creators was Fujii Yoshitoyo from Kyoto, Japan. He was born in 1868 and invented new techniques for the art of damascening. His designs were drawn by Prof. Bisei Unno of the Tokyo Fine Art School. He operated the Fujii Damascene Company from about 1925 through the mid 20th Century. In many exhibitions of this kind, Fujii was awarded first class medals for his exhibits, and to his great honor his works has been purchased by the Imperial Household. Although Fujii's works are extremely detailed and very similar to the, for example, Komai's works, they are done in the etching technique and not in Zogan. Because Fujii's company was called "Fujii Damascene Co" or "Fujii Zogan Co" there should be arts he made in a Zogan technique, but till now, none of these were discovered.
