藏传金铜佛像中的大型造像多用分片锤揲：紫铜片按经卷量度在凹凸砧上分块敲出头、手、衣，拼接焊合后整体錾刻卷草与六拏具，最后以汞齐法鎏金（约 450 ℃ 烘汞）。一尊高 60 cm 坐像需铜片 12–18 块、錾刻工时 150–250 h；錾纹深浅按造像比例量度校验，是汉藏金工交流的典型实证。
Large Tibetan gilt bronzes are usually raised in sections: copper sheet is hammered over matching stakes into head, hands and drapery, welded into a whole, then chased with scrollwork and the six ornaments, and finally fire-gilded by amalgam baked at about 450 °C. A 60 cm seated figure uses 12–18 sections and 150–250 h of chasing; chased depth is checked against canonical proportions, a hallmark of Sino-Tibetan metalwork exchange. ---
