- Résumé
- Due to their inherent three-dimensional structure and the substrata to which they are often affixed, specimens of many cryptogamic plants (e.g. lichens, mosses) are stored in small, origami-like packets instead of pressed and mounted flat on herbarium sheets. To date, herbaria specifications for the paper of these folded packets has been liberal at best. As proud custodians of a very significant lichen collection, the Canadian Museum of Nature (CMN) (Ottawa, Ontario) recognizes the need for determining a suitable packet paper that is commensurate with modem conservation standards. This research project examined Japanese washi paper to determine its suitability for lichen packet use in herbaria collections storage. Aside from the usual acid-free / archival properties, the CMN requires additional qualities when considering a long-term storage material; these attributes were used as a guideline for the experimental design. Three types of washi paper from different manufacturers were studied. After thermal accelerated ageing for 14 days at 90°C, the aged samples were tested against the unaged samples for mechanical properties including zero-span tensile strength, folding endurance, and internal tearing resistance. Chemical testing was undertaken to determine the cold extraction pH. Other tests included moisture content, grammage, optical properties, UV fluorescence, and ink deposition trials. The results of this research proved similar to previous studies: while some degradation was evident, the overall strength and stability of the papers was maintained. Though the required ability of the papers to maintain a folded shape is questionable, Japanese washi paper was revealed to be a promising material to ensure lichen specimen longevity both physically and chemically while in storage.
