Museums use several methods to preserve artefacts: (a) Climate control—maintaining specific temperature and humidity levels to prevent damage from heat, cold, or moisture. Artefacts are kept in controlled environments where temperature and humidity are constantly monitored. (b) Protective storage—using acid-free boxes, archival-quality containers, and padded storage to prevent physical damage. Delicate items are wrapped in special materials and stored separately. (c) Regular conservation—professional conservators examine and treat artefacts to prevent deterioration. This includes cleaning with appropriate methods, repairing damage, and applying protective coatings. Museums also use specialised lighting that does not damage sensitive materials, security systems to prevent theft, and restricted handling policies to minimise human contact with fragile objects.
