Material descriptions
A material record separates supplier wording, observable structure and documented properties. Descriptive colour is not a conservation property.
This collection describes enclosure forms, access routes and documentation practices for paper-based material. It is intended for reading and planning, not for directing treatment of fragile objects. Fold diagrams and record examples are original illustrations with no associated collection or accession data. Material descriptions distinguish observed features from documented properties. Decisions about a real object, its condition and its environment require the relevant professional judgement.
Practical example
Record the source of a material statement and leave unsupported fields explicitly unconfirmed.
Do not infer chemical suitability from a trade name or visual appearance.
