匠人以 1.2 mm 银板起凸一把 800 ml 茶壶。分 9 次退火、累计锤击约 6000 次，壶身由平面渐成球腹。关键控制壁厚均匀：用卡尺测厚，薄于 0.8 mm 处回锤补料。成品接缝以钎焊封合，再錾刻纹样。
A smith raised an 800 ml teapot from 1.2 mm silver sheet. Over 9 anneal cycles and ~6000 blows the flat disc became a spherical belly. Key control: uniform wall thickness — measure with calipers and re-hammer any area under 0.8 mm. The seam was closed by brazing, then chased with decoration. ---
