When selecting a humidity-controlled case for bronze sculptures, several critical factors must be considered to ensure optimal preservation. First, the case must maintain a stable relative humidity (RH) level, ideally between 40-50%, to prevent corrosion and oxidation. Fluctuations in humidity can accelerate deterioration, so a high-quality hygrometer and humidification/dehumidification system are essential.

Material compatibility is another key consideration. The interior lining should be inert and non-reactive, such as acid-free foam or archival-grade fabric, to avoid chemical interactions with the bronze. Additionally, the case should be airtight to minimize exposure to external pollutants while allowing for controlled ventilation if needed.

Size and accessibility matter as well. The case must accommodate the sculpture without crowding, and doors or panels should provide easy access for maintenance without compromising climate stability. Finally, consider the case’s placement—avoid direct sunlight or areas with temperature fluctuations to enhance its effectiveness. Investing in a well-designed humidity-controlled case ensures the longevity and beauty of bronze sculptures for generations.
