Ammonia: Chloride Assist & Humidity Control
氨熏：氯化物辅助与温湿度控制

加入氯化物可得偏"海绿/松石绿"的碱式氯化铜。做法：熏箱水碗中加**氯化铵或食盐 5–10 g/L**，氯离子参与成膜，色更偏绿、带灰调。**温湿度控制**：湿度 60–90% RH 最佳（过干几乎不反应），温度 20–30℃ 为宜（低温极慢）；氨浓度高则色快而深。偏蓝则增氨减湿，偏深绿则加湿延长时间。**注意**：氯离子会加速基体点蚀，完成后须彻底水洗并在 24 小时内封护，薄壁件不宜长期暴露。
Chlorides give a "sea-green/turquoise" basic copper chloride. Add **ammonium chloride or salt 5–10 g/L** to the chamber's water; chloride enters the film for a greener, grayish tone. **Control**: humidity 60–90% RH (dry ≈ no reaction), temperature 20–30℃ (cold is very slow); higher ammonia = faster/deeper. Bluer with more ammonia and less humidity; deeper green with more humidity and time. **Caution**: chlorides accelerate pitting — rinse thoroughly and seal within 24 h; not for thin-wall long-exposure parts. ---
