**火焰首饰**：紫铜吊坠做蓝紫渐变——抛光至镜面，夹于耐火砖，还原焰由顶扫底，顶部久→深蓝、底部短→浅黄，竖向渐变，余热定型空冷，极薄蜂蜡封护。**烘烤面板**：数块铜板同入 320℃ 控温炉保温 20 分钟，整体得均匀紫蓝色，用于建筑装饰拼板，一致性强。两者分别示范火焰法与烘烤法。
**Torch jewelry**: a blue-purple copper pendant — polish to mirror, clamp on firebrick, sweep the reducing flame top to bottom, longer on top → deep blue, short on bottom → pale yellow, vertical gradient, air-cool, thin beeswax. **Oven panel**: several copper plates in a 320℃ furnace for 20 min give an even purple-blue for architectural cladding — strong consistency. They demo torch vs oven respectively. ---
