以 3 mm 紫铜板锻造一只茶则：①下料圆片，边缘倒角 ②中心加热起凸（raising）成浅碗 ③反复退火-锤打扩大口径 ④修口沿、錾刻纹饰 ⑤酸洗抛光 ⑥可选火焰或硫化着色封护。关键点：每次锤打后必退火，防止杯壁开裂；口沿用木锤收圆保形。
Forge a 3 mm copper tea scoop: ①cut a disc, bevel edge ②heat center, raise into a shallow bowl ③anneal-and-hammer to widen the mouth ④true the rim, chase decoration ⑤pickle and polish ⑥optional flame/sulfide patina and seal. Key: anneal after every forging step to avoid wall cracks; use a wood mallet to true the rim. ---
