Ancient scrolls, especially those crafted from parchment, are delicate artifacts requiring careful handling and preservation. Their porous surface and organic composition make them susceptible to environmental changes, pests, and physical damage. Understanding the principles of parchment care is crucial for ensuring these historical documents survive for generations to come.
The most significant factors impacting parchment are temperature and humidity. Fluctuations in either can cause the material to expand and contract, leading to stress and potential cracking or warping. Ideally, parchment should be stored in a stable environment with a consistent relative humidity between 45% and 55%, and a temperature between 18°C and 20°C (65°F and 68°F). Avoid areas near radiators, direct sunlight, or exterior walls which are prone to temperature swings.
When handling parchment, always ensure your hands are clean and dry. The natural oils and moisture from skin can degrade the material over time. It is highly recommended to wear clean, white cotton gloves. Never fold or crease parchment. When unrolling a scroll, do so slowly and support the unrolled portion to prevent undue stress on the remaining rolled section. Consider using custom-made archival supports or cradles for displaying or handling fragile scrolls.
Insects such as silverfish, booklice, and carpet beetles are known to feed on parchment. Regular inspection of storage areas and the scrolls themselves is vital. Maintain a clean environment, free from dust and debris where pests can thrive. Avoid storing parchment in attics or basements where pest activity is often higher. If an infestation is suspected, consult with a professional conservator immediately.
Parchment should be stored in archival-quality boxes or tubes made from acid-free materials. Avoid plastic enclosures as they can trap moisture and gases. If displaying parchment, ensure it is out of direct light, as UV radiation can cause fading and embrittlement. Low light levels are preferred for long-term display. Always use archival mounts and frames that do not come into direct contact with the parchment surface.
Remember, if you have any doubts about the condition or care of your ancient scrolls, seeking the expertise of a qualified paper or parchment conservator is always the wisest course of action. They can provide tailored advice and treatment plans.
