Why Do Bronze Sculptures Rust?
1. Humidity: If there is too much moisture in the air, the cuprous chloride produced by the corrosion of the chloride will produce soft powdery base copper chloride after obtaining oxygen and moisture. Will continuously corrode the copper interior, causing its surface to rust and peel off.
2. Temperature: The temperature basically will not affect the bronze, unless it is abnormally high temperature.
3. The temperature and humidity around the bronze can’t be changed too fast, because the bronze will be affected by the sudden cooling and heat, and even break naturally.
