Storage and care

Labels belong with the specimen

Name, classification, find or fall data, mass, previous collection and invoice or certificate reference should remain together permanently. Never attach a label directly with unsuitable adhesive.

Dry, stable and chemically safe

The most important measure is low, stable humidity. Sealed archival containers with regenerable silica gel and a humidity indicator especially protect metal-rich specimens. Direct sunlight, condensation and large temperature swings should be avoided.

Containers, foams and labels should be archival and acid-free. Soft PVC can release plasticisers and chlorine compounds; unsuitable adhesives and paper may promote corrosion. Silica gel must be checked and dried or replaced in time.

Handling, cleaning and condition records

Clean nitrile or cotton gloves keep salts and skin oils off metal surfaces. Dust should be removed only by suitable gentle methods. Oils, water, household cleaners, acids and aggressive brushing can permanently alter surfaces and scientific information.

Periodic photographs, mass and a brief condition note reveal new cracks or rust early. Active corrosion, especially in chloride-bearing irons, belongs with an experienced conservator. Preserve the original label separately and connect it with an archival number.
