纽约设计师 Frederick Buechner 的青铜灯具系列长期与艺术铸造工坊协作：设计师交付 1:1 模型与图纸，工坊翻制硅胶模注蜡、修蜡后以陶瓷壳 6–7 层制壳，浇注硅青铜（含硅 4–5%，铸态即可抛光、免热处理）。灯臂壁厚控制 3–4 mm，铸后经 120 目喷砂与手工打磨，再以硫化钾化学着色成统一棕黑色。限定系列每版 12–30 件，模具费摊入首批交付。
Frederick Buechner's bronze lighting collections have long been produced with art foundries in New York: the designer supplies 1:1 models and drawings, the foundry replicates them in RTV silicone with injected wax, builds a 6–7 coat ceramic shell, and pours silicon bronze (4–5% Si, polishable as-cast, no heat treatment). Arms are held to 3–4 mm wall, bead-blasted at 120 mesh, hand-finished, and patinated to a uniform dark brown with potassium polysulfide. Limited editions run 12–30 pieces with tooling amortized into the first batch. ---
