A Study on the Filigree techniques of Earings in the Three-contries periods

Filigree techniques of earings in the Three-contri es peri ods which show va rious patterns will contribute to th e good opportunity of und erstandin g the ancient metal craft techniques and these will provide us with the data that can j udge not only the technical inte r-relations hips of the tempor al and the reg ional techniques but also the cultural levels. Firstly, we classified th e fi lig ree techn iqu es int o th e fi ne lin eal e la boratio ns( - fil ig ree technique in a narrow sense) and the granulation tec hniques with granules, and research their manufacturing techniques. The chise led-s trands techn iqu es which mad e by the pun ches of va rio us s ty le s how the appearance of the full-fl edged developement after the middle of the three country, especially in the latter period. From this, we can get the conclusion that these techniques are handed down the granulation techniqu es of the latter period . And we can conclude that granules are not only fused by the copper oxide as is generally known but welded using the solder. There are some di fferences between the parts and relics according to the fineness of the solder and solder ing techniques Coarse grains bounded pyrarnidically to a tip of earings have the surface textures that might be formed when they are melted, such textures appear when the alloy ratio is low, they reveal the characteristics of the hanging down type fine granulation of the Gaya region. Additionally these surface textures can be different iated by regions, they reveal the differences of the characteristics of the alloy propensity and melting techniqu es between the regional factories.
