Tortoiseshell Cat Wearing A Tracking Collar
Tortoiseshell or tortoise shell is a material produced from the shells of the larger species of tortoise and turtle, mainly the hawksbill sea turtle, which is a critically endangered species according to the IUCN Red List largely because of its exploitation for this trade. The large size, fine color, and unusual form of the hawksbill's scutes make it especially suitable. The distinctive patterning is referred to in names such as the tortoiseshell cat, several breeds of guinea pig, and the common names of several species of the butterfly genera ''Nymphalis'' and ''Aglais'', and some other uses. Uses Tortoiseshell was widely used from ancient times in the North and in Asia, until the trade was banned in 2014. It was used, normally in thin slices or pieces, in the manufacture of a wide variety of items such as combs, small boxes and frames, inlays in furniture (known as Boulle Work carried out by André-Charles Boulle), and other items: frames for spectacles, guitar picks and kn ...

Knitting Needle
A knitting needle or knitting pin is a tool in hand-knitting to produce knitted fabrics. They generally have a long shaft and taper at their end, but they are not nearly as sharp as sewing needles. Their purpose is two-fold. The long shaft ''holds'' the active (unsecured) stitches of the fabric, to prevent them from unravelling, whereas the tapered ends are used to ''form new stitches''. Most commonly, a new stitch is formed by inserting the tapered end through an active stitch, catching a loop (also called a bight) of fresh yarn and drawing it through the stitch; this secures the initial stitch and forms a new active stitch in its place. In specialized forms of knitting the needle may be passed between active stitches being held on another needle, or indeed between/through inactive stitches that have been knit previously. The size of a needle is described first by its diameter and secondly by its length. The size of the new stitch is determined in large part by the diamete ...

Cabinetmaker
A cabinet is a case or cupboard with shelves and/or drawers for storing or displaying items. Some cabinets are stand alone while others are built in to a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood (solid or with veneers or artificial surfaces), coated steel (common for medicine cabinets), or synthetic materials. Commercial grade cabinets usually have a melamine-particleboard substrate and are covered in a high pressure decorative laminate, commonly referred to as Wilsonart or Formica. Cabinets sometimes have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Cabinets may have one or more doors, drawers, and/or shelves. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens. A cabinet intended to be used in a bedroom and with several drawers typically placed one above another in one or more column ...

André Charles Boulle
André-Charles Boulle (11 November 164229 February 1732), ''le joailler du meuble'' (the "furniture jeweller"), became the most famous French cabinetmaker and the preeminent artist in the field of marquetry, also known as "inlay". Boulle was "the most remarkable of all French cabinetmakers". Jean-Baptiste Colbert (29 August 1619 – 6 September 1683) recommended him to Louis XIV of France, the "Sun King" (), as "the most skilled craftsman in his profession". Over the centuries since his death, his name and that of his family has become associated with the art he perfected, the inlay of tortoiseshell, brass and pewter into ebony. It has become known as '' Boulle Work'', and the École Boulle (founded in 1886), a college of fine arts and crafts and applied arts in Paris, continues today to bear testimony to his enduring art, the art of inlay. Life in 1677, on his marriage certificate, André-Charles Boulle gave his birth date, for posterity, as being 11 November 1642. No other d ...

Periplus Of The Erythraean Sea
The ''Periplus of the Erythraean Sea'' ( grc, Περίπλους τῆς Ἐρυθρᾶς Θαλάσσης, ', modern Greek '), also known by its Latin name as the , is a Greco-Roman periplus written in Koine Greek that describes navigation and trading opportunities from Roman Egyptian ports like Berenice Troglodytica along the coast of the Red Sea, and others along Horn of Africa, the Persian Gulf, Arabian Sea and the Indian Ocean, including the modern-day Sindh region of Pakistan and southwestern regions of India. The text has been ascribed to different dates between the first and third centuries, but a mid-first-century date is now the most commonly accepted. While the author is unknown, it is clearly a first-hand description by someone familiar with the area and is nearly unique in providing accurate insights into what the ancient Hellenic world knew about the lands around the Indian Ocean.

Lyre
The lyre () is a stringed musical instrument that is classified by Hornbostel–Sachs as a member of the lute-family of instruments. In organology, a lyre is considered a yoke lute, since it is a lute in which the strings are attached to a yoke that lies in the same plane as the sound table, and consists of two arms and a crossbar. The lyre has its origins in ancient history. Lyres were used in several ancient cultures surrounding the Mediterranean Sea. The earliest known examples of the lyre have been recovered at archeological sites that date to c. 2700 BCE in Mesopotamia. The oldest lyres from the Fertile Crescent are known as the eastern lyres and are distinguished from other ancient lyres by their flat base. They have been found at archaeological sites in Egypt, Syria, Anatolia, and the Levant. The round lyre or the Western lyre also originated in Syria and Anatolia, but was not as widely used and eventually died out in the east c. 1750 BCE. The round lyre, called so fo ...

Chelys
The chelys or chelus ( el, χέλυς, la, testudo, both meaning "turtle" or "tortoise"), was a stringed musical instrument, the common lyre of the ancient Greeks, which had a convex back of tortoiseshell or of wood shaped like the shell. The word ''chelys'' was used in allusion to the oldest lyre of the Greeks, which was said to have been invented by Hermes. According to the ''Homeric Hymn to Hermes'', he came across a tortoise near the threshold of his mother's home and decided to hollow out the shell to make the soundbox of an instrument with seven strings. The word has been applied arbitrarily since classic times to various stringed instruments, some bowed and some plucked, probably owing to the back being much vaulted. Athanasius Kircher (''Musurgia universalis'', 486) applied the name of chelys to a kind of viol with eight strings. Numerous representations of the chelys lyre or testudo occur on Greek vases, in which the actual tortoiseshell is depicted. A good illustration ...

Brand
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Delrin
Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac and Hostaform. POM is characterized by its high strength, hardness and rigidity to −40 °C. POM is intrinsically opaque white because of its high crystalline composition but can be produced in a variety of colors. POM has a density of 1.410–1.420g/cm3. Typical applications for injection-molded POM include high-performance engineering components such as small gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, gun parts, knife handles, and lock systems. The material is widely used in the automotive and consumer electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellulose Acetate
In biochemistry, cellulose acetate refers to any acetate ester of cellulose, usually cellulose diacetate. It was first prepared in 1865. A bioplastic, cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses; it is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. In cellulose acetate film, photographic film, cellulose acetate film replaced nitrate film in the 1950s, being far less flammable and cheaper to produce. History In 1865, French chemist Paul Schützenberger discovered that cellulose reacts with acetic anhydride to form cellulose acetate. The German chemists Arthur Eichengrün and Theodore Becker invented the first soluble forms of cellulose acetate in 1903. In 1904, Camille Dreyfus (chemist), Camille Dreyfus and his younger brother Henri Dreyfus, Henri performed chemical research and development on cellulose acetate in a shed in their father's garden in Basel ...

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...
