1986年7~8月广汉三星堆两个祭祀坑共出土了青铜器、金器、玉器、石器及陶器各类文物近千余件。其中青铜器就达400余件。经过文物修复工作者多年的努力,现在绝大部分已经修复复原,已在国内外展出并得到了一致的好评。现在仍然还有很少的文物正在研究修复中。青铜大型人面具(标本号K2③:3 14)的研究修复,是近年来三星堆祭祀坑出土文物修复工作的又一重大成果。两个祭祀坑出土的青铜器,均被火烧过。有的青铜器被火烧变形,还曾被人为敲砸毁坏,入坑填土时层层夯实,因此青铜器的变形在所难免,为修复增添了不少的困难。笔者20年来,一直主持和参与三星堆文物的修复工作。其中包括青铜面具的修复,对于它们的造型特点有所研究,其铸造工艺也有较深的了解,为修复复原这件青铜大面具 July 1986 7 August Guanghan Sanxingdui two sacrificial pit were unearthed bronze, gold, jade, stone and pottery all kinds of artifacts nearly a thousand pieces. Of which more than 400 bronze pieces. After years of efforts by remediation workers, most of them have now been restored and restored. They have been exhibited at home and abroad and received unanimous praise. There are still a few relics still under study. The research and restoration of bronze large-scale masks (specimen number K2③: 3 14) are another major achievement of the restoration of cultural relics excavated in the sacrificial pit of Sanxingdui mound in recent years. Bronze ware unearthed from two sacrificial pits was burnt by fire. Some bronze was deformed by fire, but also been knocked smashed by man, when the pit fill compaction layers, so the deformation of the bronze is inevitable, adding a lot of difficulties for the repair. For 20 years, I have been in charge of and involved in the restoration of Sanxingdui relics. Including the restoration of bronze masks, for their modeling characteristics have been studied, the casting process also has a deeper understanding of the restoration of this large bronze mask
