Calf Skin
Calfskin or calf leather is a leather or membrane produced from the hide of a calf, or juvenile domestic cattle. Calfskin is particularly valuable because of its softness and fine grain, as well as durability. It is commonly used for high-quality clothing, shoes, wallets, and similar products, as well as traditional leather bookbindings. In these contexts, just "calf" is commonly used. Fine calfskin is one of the skins used for vellum and parchment manuscripts. In Spanish, the word is ''Ternera/Novillo'', referring to leather from animals less than three years old. Chickenskin, despite its name, is a form of calfskin made using the skin of unborn calves. In fashion, soft finished calfskin is sometimes described as'' veau velours'' (French for "velvet calf"). See also *Goldbeater's skin, made from the intestine of a calf *Sheepskin (material) Sheepskin is the hide of a sheep, sometimes also called lambskin. Unlike common leather, sheepskin is tanned with the fleece intact, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalb Schwarzgefaerbt
The Banu Kalb ( ar, بنو كلب) was an Arab tribe which mainly dwelt in the desert between northwestern Arabia and central Syria (region), Syria. The Kalb was involved in the tribal politics of the Limes Arabicus, eastern frontiers of the Byzantine Empire, possibly as early as the 4th century. By the 6th century, the Kalb had largely adopted Christianity and came under the authority of the Ghassanids, the chief Arab federates of the Byzantines. During the lifetime of the Islamic prophet Muhammad, a number of his sahaba, close companions were Kalbi tribesmen, most prominently Zayd ibn Haritha and Dihyah Kalbi, Dihya al-Kalbi, but the bulk of the tribe remained Christian at the time of Muhammad's death in 632. They began converting in large numbers when the Muslims made significant progress in the Muslim conquest of Syria, conquest of Byzantine Syria, where the Kalb took a neutral stance. As a massive tribe with considerable military experience, the Kalb was sought after as a key ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extract From Burchard Of Worms' Decretum
An extract is a substance made by extraction (chemistry), extracting a part of a raw material, often by using a solvent such as ethanol, Cooking oil, oil or water. Extracts may be sold as tinctures, Absolute (perfumery), absolutes or in powder form. The Aroma compound, aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange (fruit), orange, peppermint, pistachio, rose, spearmint, vanilla, Violet (plant), violet, rum, and wintergreen. Extraction techniques Most natural essences are obtained by extracting the essential oil from the feedstock, such as blossoms, fruit, and roots, or from intact plants through multiple techniques and methods: * Ram press (food), Expression (juicing, Fruit press, pressing) involves physical extraction material from feedstock, used when the oil is plentiful and easily obtained from materials such a ...

Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Membrane
A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another. Biological membranes, in the form of eukaryotic cell membranes, consist of a phospholipid bilayer with embedded, integral and peripheral proteins used in communication and transportation of chemicals and ions. The bulk of lipids in a cell membrane provides a fluid matrix for proteins to rotate and laterally diffuse for physiological functioning. Proteins are adapted to high membrane fluidity environment of the lipid bilayer with the presence of an annular lipid shell, consisting of lipid molecules bound tightly to the surface of integral membrane proteins. The cell membranes are different from the isolating tissues formed by layers of cells, such as mucous membranes, basement membranes, and serous membranes. Composition ...

Calf (animal)
A calf ( : calves) is a young domestic cow or bull. Calves are reared to become adult cattle or are slaughtered for their meat, called veal, and hide. The term ''calf'' is also used for some other species. See "Other animals" below. Terminology "Calf" is the term used from birth to weaning, when it becomes known as a ''weaner'' or ''weaner calf'', though in some areas the term "calf" may be used until the animal is a yearling. The birth of a calf is known as ''calving''. A calf that has lost its mother is an orphan calf, also known as a ''poddy'' or ''poddy-calf'' in British. ''Bobby calves'' are young calves which are to be slaughtered for human consumption. A ''vealer'' is a calf weighing less than about which is at about eight to nine months of age. A young female calf from birth until she has had a calf of her own is called a ''heifer'' (). In the American Old West, a motherless or small, runty calf was sometimes referred to as a dodie. The term "calf" is also used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domestic Cattle
Cattle (''Bos taurus'') are large, domestication, domesticated, Cloven hoof, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hide (skin), hides, which are used to make leather. They are used as riding animals and draft animals (oxen or wikt:bullock, bullocks, which pull carts, plows and other implements). Another product of cattle is Cow dung, their dung, which can be used to create manure or fuel. In some regions, such as parts of India, Cattle in religion, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clothing
Clothing (also known as clothes, apparel, and attire) are items worn on the body. Typically, clothing is made of fabrics or textiles, but over time it has included garments made from animal skin and other thin sheets of materials and natural products found in the environment, put together. The wearing of clothing is mostly restricted to human beings and is a feature of all human societies. The amount and type of clothing worn depends on gender, body type, social factors, and geographic considerations. Garments cover the body, footwear covers the feet, gloves cover the hands, while hats and headgear cover the head. Eyewear and jewelry are not generally considered items of clothing, but play an important role in fashion and clothing as costume. Clothing serves many purposes: it can serve as protection from the elements, rough surfaces, sharp stones, rash-causing plants, insect bites, by providing a barrier between the skin and the environment. Clothing can insulate against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bookbinding
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of ''signatures'', sheets of paper folded together into sections that are bound, along one edge, with a thick needle and strong thread. Cheaper, but less permanent, methods for binding books include loose-leaf rings, individual screw-posts (binding posts), twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack of signatures is wrapped in a flexible cover or is attached to stiffened boards. Finally, an attractive cover is placed onto the boards, which includes the publisher's information, and artistic decorations. The trade of binding books is in two parts; (i) stationery binding (vellum binding) for books intended for handwritten entries, such as accounting ledgers, business journals, blank-page books, and guest logbooks, and notebooks, manifold books, day books, diaries, and portfolios. (ii) letterpress printing and binding deals with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vellum
Vellum is prepared animal skin or membrane, typically used as writing material. Parchment is another term for this material, from which vellum is sometimes distinguished, when it is made from calfskin, as opposed to that made from other animals, or otherwise being of higher quality. Vellum is prepared for writing or printing on, to produce single pages, scrolls, codices, or books. Modern scholars and custodians increasingly use only the less specific, potentially-confusing term "membrane".Stokes and Almagno 2001, 114Clemens and Graham 2007, pp. 9–10. Depending on factors such as the method of preparation it may be very hard to determine the animal species involved (let alone its age) without using a laboratory, and the term avoids the need to distinguish between vellum and parchment. Vellum is generally smooth and durable, although there are great variations depending on preparation and the quality of the skin. The manufacture involves the cleaning, bleaching, stretching ...

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. It may be called animal membrane by libraries and museums that wish to avoid distinguishing between ''parchment'' and the more-restricted term ''vellum'' (see below). Parchment and vellum Today the term ''parchment'' is often used in non-technical contexts to refer to any animal skin, particularly goat, sheep or cow, that has been scraped or dried under tension. The term originally referred only to the skin of sheep and, occasionally, goats. The equivalent material made from calfskin, which was of finer quality, was known as ''vellum'' (from the Old French or , and ultimately from the Latin , meaning a calf); while the finest of all was ''uterine vellum'', taken from a calf foetus or still ...

Goldbeater's Skin
Goldbeater's skin is the processed outer membrane of the intestine of an animal, typically cattle, which is valued for its strength against tearing. The term derives from its traditional use as durable layers interleaved between sheets of gold stock during the process of making gold leaf by goldbeating, as a batch process producing many "leaves" at the same time. In the early modern production of airships, application of its high strength-to-weight ratio and reliability were crucial for building at least the largest examples. Manufacture To manufacture goldbeater's skin, the gut of oxen (or other cattle) is soaked in a dilute solution of potassium hydroxide, washed, stretched, beaten flat and thin, and treated chemically to prevent putrefaction. A pack of 1,000 pieces of goldbeater's skin requires the gut of about 400 oxen and is thick. Up to 120 sheets of gold laminated with goldbeater's skin can be beaten at the same time, since the skin is thin and elastic and does not ...

Sheepskin (material)
Sheepskin is the hide of a sheep, sometimes also called lambskin. Unlike common leather, sheepskin is tanned with the fleece intact, as in a pelt.Delbridge, Arthur, "The Macquarie Dictionary", 2nd ed., Macquarie Library, North Ryde, 1991 Uses Sheepskin is used to produce sheepskin leather products and soft wool-lined clothing or coverings, including gloves, hats, slippers, footstools, automotive seat covers, baby and invalid rugs and pelts. Sheepskin numnahs, saddle pads, saddle seat covers, sheepskin horse boots, tack linings and girth tubes are also made and used in equestrianism. The fleece of sheepskin has excellent insulating properties and it is also resistant to flame and static electricity. Wool is considered by the medical profession to be hypoallergenic. Sheepskin is a natural insulator, and draws perspiration away from the wearer and into the fibers. There, it traps between 30 and 36 percent of its own weight in moisture, and it is for this reason that sheepskin is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
