Parchment is a thin material made from calfskin, sheepskin Sheepskin is the hide of a sheep, sometimes also called lambskin or lambswool. Unlike common leather, sheepskin is tanned with the fleece intact, as in a pelt or goatskin Non tanned goatskin is used for parchment or for drumheads or sounding boards of some musical instruments, e.g., mišnice in medieval Europe, bodhrán in Ireland, esraj in India and for instrumental drum skin named bedug in Indonesia, often split. Its most common use was as a material for writing on, for documents, notes, or the pages of a book A book is a set or collection of written, printed, illustrated, or blank sheets, made of paper, parchment, or other various material, usually fastened together to hinge at one side. A single sheet within a book is called a leaf, and each side of a leaf is called a page. A book produced in electronic format is known as an electronic book, codex A codex is a book in the format used for modern books, with separate pages normally bound together and given a cover. It was a Roman invention that replaced the scroll, which was the first form of book in all Eurasian cultures.[citation needed] or manuscript A manuscript or handwrit is a recording of information that has been manually created by someone or some people, such as a hand-written letter, as opposed to being printed or reproduced some other way. The term may also be used for information that is hand-recorded in other ways than writing, for example inscriptions that are chiselled upon a hard. It is distinct from leather Leather is a durable and flexible material created via the tanning of putrescible animal rawhide and skin, primarily cattlehide. It can be produced through different manufacturing processes, ranging from cottage industry to heavy industry in that parchment is limed Liming usually refers to any process which traditionally accomplished with lime or Calcium hydroxide. Hence it may refer to: but not tanned Tanning is the process of making leather, which does not easily decompose, from the skins of animals, which do. Often this uses tannin, an acidic chemical compound. Coloring may occur during tanning. A tannery is the term for a place where these skins are processed, therefore it is very reactive with changes in relative humidity The relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor (ew) in the mixture to the saturated vapor pressure of water at a prescribed temperature and is not waterproof. The finer qualities of parchment are called vellum Vellum is mammal skin prepared for writing or printing on, to produce single pages, scrolls, codices or books. It is generally smooth and durable, although there are great variations depending on preparation, the quality of the skin and the type of animal used. The manufacture involves the cleaning, bleaching, stretching on a frame, and scraping.
