某 2.4 m 高紫铜浮雕墙以「火焰打底 + 激光提色」完成：先丙烷火焰整体做暖棕基色（氧化膜约 10 nm），抛光保留高光区；再用 60 W 激光在浮雕凹部扫描蓝紫渐变（30–40 nm），凸部经预蜡屏蔽保持基色。全程 6 h，比纯手工火焰（约 20 h、报废 1 块）效率提高 3 倍且图案可复刻。启示：大尺度作品的精细色区交给激光，宏观底色仍以火焰最经济。
A 2.4 m copper relief wall was finished by "torch base + laser accents": propane flame first set a warm-brown base (~10 nm oxide), with high spots polished and wax-masked; then a 60 W laser scanned blue-violet gradients (30–40 nm) into the recesses. Total 6 h versus about 20 h by hand-torch (one panel scrapped), a 3× gain with a fully repeatable pattern. The lesson: give fine color zones to the laser, keep broad base tones on the torch.
