Reversible Treatment of Cracked & Chipped Enamel
珐琅器裂纹与崩瓷的可逆性处理
标签：长期维护, 崩瓷修补, 可逆修复, 湿度控制, UV树脂
传世珐琅器细裂纹稳定无扩展时可不做干预，仅将环境湿度控制在 45±5% RH，防金属胎锈胀挤压釉层。崩瓷小面积缺失用 UV 固化丙烯酸树脂调矿物颜料补全，可逆且不进窑；较大缺失若器物允许复烧（掐丝完好），以 610–640℃ 低温补釉。禁忌：树脂补料禁用含溶剂清洁剂擦拭；已裂器物禁止温差骤变（如热水洗）。修复档案须附热像图与补点位置图，每次复检拍照对比，量化裂纹扩展速率。
Stable hairline cracks on historic enamel need no intervention—just 45±5% RH to stop the metal core rusting and squeezing the glaze. Small chips are filled with UV-cured acrylic tinted with mineral pigments, reversible and kiln-free; larger losses on pieces that can safely refire (filigree intact) take low-temperature refills at 610–640℃. Don'ts: no solvent cleaners on resin fills, no thermal shocks (hot-water washing) on cracked work. Archives carry thermographs and fill maps, re-photographed at each check to quantify crack growth.
