透光珐琅步骤：①铜胎打磨、酸洗去氧化、反复烧"底釉"（透明）填满孔隙 ②筛涂/湿涂目标透明釉（薄而匀，约 0.5–1 mm）③入窑 800–850℃ 烧 1–3 分钟至釉面镜亮（"出光"）④如需叠色，冷却后再次薄涂复烧。关键：每层薄、烧透、避免气泡；透光釉要透出洁净胎色，故胎面预处理极重要。
Transparent enamel steps: ①prep copper: grind, pickle, fire a "counter/enamel" base coat to fill pores ②sift/wet-apply the target transparent (thin, even, ~0.5–1 mm) ③fire 800–850℃ for 1–3 min until glossy ("going to glass") ④for layered color, cool then re-coat and refire. Keys: thin, fully fused, no bubbles; transparent shows the clean base, so base prep is critical. ---
