Glossary
Welcome to your comprehensive guide to the language of the art world. Navigating this industry requires a unique vocabulary that bridges the gap between creative expression and technical precision.
Cold Storage (Photographic & Film Media)
A specialised, climate-controlled preservation environment designed to drastically slow the chemical degradation of photographic prints, negatives, and motion picture film. By maintaining sub-ambient temperatures and low relative humidity (RH), cold storage halts or delays destructive processes like 'vinegar syndrome' (acetate degradation), colour dye fading, and silver mirroring.
Logistical & Practical Significance
Cold storage is generally categorised into Cool (10°C - 13°C) for active use, Cold (0°C - 4°C) for medium-term storage, and Frozen (-18°C or lower) for long-term preservation of unstable media like cellulose nitrate, acetate film, and contemporary colour prints.
Acclimatisation Protocol (Staging): Artworks cannot be moved directly from a freezing vault to room temperature, as condensation will form on the emulsion and ruin the media. Logistics workflows must build in a strict staging period—often 24 to 48 hours—allowing items to slowly warm up inside vapour-proof packaging before being opened.
Packaging (Vapour-Proofing): Prior to entering cold storage, materials must be conditioned to low humidity and sealed in specialised, multi-layered moisture barrier bags (such as Marvelseal) to protect them from fluctuating moisture levels inside the vault.
