Abstract

The ancient tombs in Imdang of Gyeongsan, a representative historic site of Silla culture,are a group of ancient tombs built by local powers of Silla during the Three Kingdoms Period whichexisted fragmentarily in written records as the tomb of the ruling class in Apdokguk(押督國). In theancient tomb Imdang 1A, where the appearance at the time of the burial was confirmed, the gilt-coppercrown ornament with a bird wing-shaped decoration was excavated showing the relationship betweenthe central Silla and the ruling powers in the local provinces. This the gilt-copper crown ornamentwith a bird wing-shaped decoration was produced in the order of ① cutting and making of eachcomponent, ② carving circular patterns, ③ gilding, ④ joining the front and wing ornament, ⑤punching for wire connection, ⑥ attaching the spangles. The front, wing ornament and circularspangles(Dalgae) were made with a thin copper plate, and the front and wing ornament overlappedeach other with a size of about 5 mm. And it was jointed with three metal rivets with a square crosssection. The circular patterns, carved on the border between the front and wing ornament, was carvedin the shape of a circular dot by chiseling in the vertical direction with a round-tip carving tool. Thegilt-copper wire used to connect the spangles(Dalgae) was first thinned by hammering. After that,thinner and more uniform wires in thickness was drawn using the drawing technique. The gilt-copperwires were inserted into the spangles(Dalgae) and twisted three times so that they were of similarlength. The wing ornament and circular spangles were gilded with a thickness of 3 to 5 µm, andthe gilded layer of the wire was the thinnest at 1 to 4 µm. To manufacture the gilt-copper crownornament with a bird wing-shaped decoration, the form was made with copper as the basic materialand the surface was gilded with the amalgam gilding technique that mixes gold and mercury.
