A custodian's habits
Antique thecae, relic cards and church documents are fragile survivors. A few sensible habits keep them stable — and preserve the provenance that gives them their meaning.
The guiding principle for any antique of this kind is stability and minimal intervention. You are a custodian, not a restorer: the goal is to slow change, not to “improve” a piece. Most damage to relics and their documents comes not from age but from well-meant handling, cleaning and repair.
Do & don't
Do
- Handle as little as possible, with clean dry hands; support the whole object, not just an edge.
- Keep the theca and its authentica together — always store and sell them as one.
- Store away from direct light, in stable, moderate conditions.
- Keep documents flat in acid-free folders or sleeves.
- Consult a professional conservator for any repair or cleaning.
Don't
- Never open a sealed theca or lift its wax seal.
- Don't polish metal reliquaries — you strip patina and thin gilding.
- Don't use tape, glue or lamination on paper; the damage is irreversible.
- Don't store in attics, basements or beside radiators — heat and damp are the enemies.
- Don't attempt DIY restoration or “freshening up.”
The environment, at a glance
- A stable, moderate temperature — avoid swings and any heat source.
- Moderate humidity (roughly 45–55%): damp invites mould; very dry air makes paper and wax brittle.
- Out of direct sunlight and strong artificial light — textiles, paper and wax all fade.
- Where a piece is framed for display, UV-filtering glass and a secure mount help.
- Some airflow, but never a draught carrying dust or damp.
When in doubt, do less. Keeping the seal, the cedula and the authentica intact is not only good conservation — it is the preservation of provenance, which is the whole point.
This is general guidance for handling and storage, not a substitute for a professional conservator. For valuable, damaged or unusual pieces, seek qualified advice.
