Parchment. Parchment is a writing material made from specially prepared untanned skins of animals—primarily sheep, calves, and goats. It has been used as a writing medium for over two millennia. Vellum is a finer quality parchment made from the skins of young animals such as lambs and young calves.
Parchment can also be stored in envelopes constructed out of polyester sheets. [16] For the long-term preservation of organic material like parchment, the ideal temperature range is 10–15 °C (50–59 °F) with a relative humidity level of 30–50%. The ideal storage and display environment is oxygen-free, as oxygen prevalence has been shown ...
The conservation and restoration of books, manuscripts, documents, and ephemera is an activity dedicated to extending the life of items of historical and personal value made primarily from paper, parchment, and leather. When applied to cultural heritage, conservation activities are generally undertaken by a conservator.
Vellum. Vellum is prepared animal skin or membrane, typically used as writing material. It is often distinguished from parchment, either by being made from calfskin (rather than the skin of other animals), [1] or simply by being of a higher quality. [2] Vellum is prepared for writing and printing on single pages, scrolls, and codices (books).
Problems can occur when parchment is exposed to high humidity for a long period of time. For example, collagen in the pages could dissolve and stick together. [11] These problems are further compounded by the fact that pigments do not dye parchment; instead, they lie on the surface of the parchment and so are rather fragile.
After its origin in central China, the production and use of paper spread steadily. It is clear that paper was used at Dunhuang by 150 CE, in Loulan in the modern-day province of Xinjiang by 200, and in Turpan by 399. Paper was concurrently introduced in Japan sometime between the years 280 and 610.
Papyrus' last appearance in the Merovingian chancery was with a document from 692 A.D., though it was known in Gaul until the middle of the following century. The latest certain dates for the use of papyrus in Europe are 1057 for a papal decree (typically conservative, all papal bulls were on papyrus until 1022), under Pope Victor II , [ 10 ...
A scroll is usually partitioned into pages, which are sometimes separate sheets of papyrus or parchment glued together at the edges. Scrolls may be marked divisions of a continuous roll of writing material. The scroll is usually unrolled so that one page is exposed at a time, for writing or reading, with the remaining pages rolled and stowed to ...
