印度泰米尔纳德邦的 Vishwakarma 金匠世系自朱罗王朝（9–13 世纪）起手工下凹制作半球圣器与灯盏：铜银合金片在手凿石窝（约 12 级、每级深差 5 mm）中逐级沉入，以姜黄水作退火润滑，一件浅浮雕灯碗历时 3–5 天。口传的"七圈走锤法"规定每圈锤距不超过锤面直径的 1/3，是该世系列入地方非遗名录的核心技艺。
In Tamil Nadu the Vishwakarma goldsmith lineages have sunk hemispherical ritual vessels and lamps since the Chola era (9th–13th c.): copper-silver sheet is sunk stepwise through hand-carved stone cavities (about 12 grades, 5 mm depth step), lubricated with turmeric water, and a shallow-relief lamp bowl takes 3–5 days. Their oral "seven-ring hammering"—strike spacing under one-third of the face diameter—is the core skill of the local heritage listing. ---
