Faturan
Faturan, in Middle Eastern beadwork, is a material used to make beads, notably in the making of komboloi and misbaha. History The creation of "Faturan" is thought to have originated by a chemist. He was melting down the filings left after carving beads from amber and mixed these remnants with other natural resins, such as mastika, frankincense, colophony, and turpentine, to mold individual beads from natural substances. Unfortunately, his original formula has long since been lost. "Bakelite" and "Parkesine" are both synthetic resins named after their inventors. And so "Faturan", named after its original inventor, became a brand of cast thermosetting phenol formaldehyde resin, similar to Bakelite and Catalin, manufactured by Traun & Son of Hamburg., developed in the early 20th century, and produced until the 1940s. In the bead trade In the bead trade, "Faturan" is thought to be a mixture of natural amber shavings with other materials, and is described as having been invented ...

Bakelite
Polyoxybenzylmethylenglycolanhydride, better known as Bakelite ( ), is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York in 1907, and patented on December 7, 1909 (). Because of its electrical nonconductivity and heat-resistant properties, it became a great commercial success. It was used in electrical insulators, radio and telephone casings, and such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. The " retro" appeal of old Bakelite products has made them collectible. The creation of a synthetic plastic was revolutionary for the chemical industry, which at the time made most of its income from cloth dyes and explosives. Bakelite's commercial success inspired the industry to develop other synthetic plastics. In recognition of its significance as the world's first commercial ...

Beadwork
Beadwork is the art or craft of attaching beads to one another by stringing them onto a thread or thin wire with a sewing or beading needle or sewing them to cloth. Beads are produced in a diverse range of materials, shapes, and sizes, and vary by the kind of art produced. Most often, beadwork is a form of personal adornment (e.g. jewelry), but it also commonly makes up other artworks. Beadwork techniques are broadly divided into several categories, including loom and off-loom weaving, stringing, bead embroidery, bead crochet, bead knitting, and bead tatting. Ancient beading The art of creating and utilizing beads is ancient, and ostrich shell beads discovered in Africa can be carbon-dated to 10,000 BC. Faience beads, a type of ceramic created by mixing powdered clays, lime, soda, and silica sand with water until a paste forms, then molding it around a stick or straw and firing until hard, were notably used in ancient Egyptian jewelry from the First Dynasty (beginni ...

Bead
A bead is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood, or pearl and with a small hole for threading or stringing. Beads range in size from under to over in diameter. Beads represent some of the earliest forms of jewellery, with a pair of beads made from '' Nassarius'' sea snail shells dating to approximately 100,000 years ago thought to be the earliest known example. Beadwork is the art or craft of making things with beads. Beads can be woven together with specialized thread, strung onto thread or soft, flexible wire, or adhered to a surface (e.g. fabric, clay). Types of beads Beads can be divided into several types of overlapping categories based on different criteria such as the materials from which they are made, the process used in their manufacturing, the place or period of origin, the patterns on their surface, or their general shape. In some cases, such as millefiori an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komboloi
Worry beads or kombolói, kompoloi ( el, κομπολόι, , ''bead collection''; plural: , ) is a string of beads manipulated with one or two hands and used to pass time in Greek and Cypriot culture. Unlike the similar prayer beads used in many religious traditions, worry beads have no religious or ceremonial purpose. Etymology Modern Greek κομπολόι is derived from κομβολόγιον κόμπο-λέω > κομπολόι. This etymology accounts for the fact that κομπολόι evolved from ''κομποσκοίνι'', the Greek word for prayer rope. Use Worry beads have several uses in Greek culture, including: *relaxation, enjoyment, and generally passing the time *as an amulet, to guard against bad luck *used by people who wish to limit smoking *as a mark of power and social prestige. This is especially true in the case of expensive worry beads made of silver or amber. Many prominent Greeks were users and collectors of worry beads, including former Prime Minist ...

Misbaha
A ''Misbaha'' ( ar, مِسْبَحَة, misbaḥa), ''subḥa'' ( ar, سُبْحَة, links=no) (Arabic, Kurdish and Urdu), ''tasbīḥ'' ( ar, تَسْبِيح, links=no) (Iran, India, Afghanistan, Tajikistan, Bangladesh and Pakistan), or ''tespih'' (Turkish, Bosnian and Albanian) is prayer beads often used by Muslims for the tasbih, the recitation of prayers, the dhikr, as well as to glorify Allah. Use A misbaḥah is a tool that is used as an aid to perform dhikr, including the names of God in Islam, and after regular prayer. It is often made of wooden or plastic beads, but also of olive seeds, ivory, pearls, and semi-precious stones such as carnelian, onyx, and amber. A typical misbahah consists of three groups of beads, separated by two distinct beads (called ''imām''s) along with one larger piece (called the ''yad'') to serve as the handle. The exact number may vary, but they usually consist of 99 beads to assist in the glorification of God following prayers: 33 Tasb ...

Thermosetting
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a curing agent (''catalyst'', '' hardener''). Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network. The starting material for making thermosets is usually malleable or liquid prior to curing, and is often designed to be molded into the final shape. It may also be used as an adhesive. Once hardened, a thermoset cannot be melted for reshaping, in contrast to thermoplastic polymers which are commonly produced and distributed in the form of pellets, and shaped into the final product for ...

Phenol Formaldehyde Resin
Phenol formaldehyde resins (PF) or phenolic resins (also infrequently called phenoplasts) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics). They have been widely used for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives. They were at one time the primary material used for the production of circuit boards but have been largely replaced with epoxy resins and fiberglass cloth, as with fire-resistant FR-4 circuit board materials. There are two main production methods. One reacts phenol and formaldehyde directly to produce a thermosetting network polymer, while the other restricts the formaldehyde to produce a prepolymer known as novolac which can be moulded and then cured with the addition of more formaldehyde and heat.A. Gardziella, L.A. Pilato, A. Knop, Phenolic Resins: Che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catalin
Catalin is a brand name for a thermosetting polymer developed and trademarked in 1927 by the American Catalin Corporation of New York City, when the patent on Bakelite expired that year. A phenol formaldehyde resin, it can be worked with files, grinders, and cutters, and polished to a fine sheen. Catalin is produced by a two-stage process, different than other types of phenolic resins, and does not contain fillers, such as sawdust or carbon black. Catalin is transparent, near colorless, rather than opaque. Unlike other phenolics, it can be produced in bright colors or even marbled. This fact has made Catalin more popular than other types of Bakelite for consumer products. Catalin is heavy, quite greasy in feel, and as hard as brass. It is heat resistant and does not soften under boiling water. Like Bakelite, it gives off a distinctive phenolic odour when heated and can be tested using Simichrome, which turns from pink to yellow. Due to oxidation, older Catalin items darken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
