Wobble Board
The wobble board is a musical instrument invented and popularized by Australian musician and artist Rolf Harris, and is featured in his best-known song " Tie Me Kangaroo Down, Sport". A wobble board, like some other musical instruments, can be ornately decorated because its large surface area can act as a canvas without detracting from its musical capability. The instrument is played by holding the board lengthwise with the hands holding the edges and flicking the board outward, thereby making a characteristic "whoop-whoop" noise. The angle at which the board is held, and the way the board is "flicked", can alter the timbre of the sound produced. It is similar to the thunder sheet, a metal instrument used to imitate the sound of thunder in 18th century theatre. History According to an interview he gave to Tony Barrell for ''The Sunday Times Magazine'' in 2001, Harris discovered the musical properties of hardboard by chance in 1959, when he was about to paint a portrait of the ...

Musical Instrument
A musical instrument is a device created or adapted to make Music, musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an ''#Instrumentalist, instrumentalist''. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn (music), horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melody, melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The exact date and specific origin of the first device considered a musical instrument, is widely disputed. The oldest object identified by scholars as a musical instrument, is Divje Babe flute, a simple flute, dated back 50,000–60,000 years. Many scho ...

Oil Paint
Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. Oil paint also has practical advantages over other paints, mainly because it is waterproof. The earliest surviving examples of oil paint have been found in Asia from as early as the 7th century AD, in examples of Buddhist paintings in Afghanistan. Oil-based paints made their way to Europe by the 12th century and were used for simple decoration, mostly on wood. Common modern applications of oil paint are in finishing and protection of wood in buildings and exposed metal structures such as ships and bridges. Its hard-wearing properties and luminous colors make it desirable for both interior and exterior use on wood and metal. Due to its slow-drying properties, it has recently been used in paint-on-glass animation. The thickness of the coat has considerable bearing on the time required for drying: thin coats of oil paint dry relatively quickly. The vi ...

Australian Inventions
This is a timeline of Australian inventions consisting of products and technology invented in Australia from pre-European-settlement in 1788 to the present. The inventions are listed in chronological order based on the date of their introduction. Australian inventions include the very old, such as woomera, and the very new, such as the scramjet, first fired at the Woomera rocket range. The Australian government has suggested that Australian inventiveness springs from the nation's geography and isolation. Perhaps due to its status as an island continent connected to the rest of the world only via air and sea, Australians have been leaders in inventions relating to both maritime and aeronautical matters, including powered flight, the black box flight recorder, the inflatable escape slide, the surf ski and the wave-piercing catamaran winged keel. Since the earliest days of European settlement, Australia's main industries have been agriculture and mining. As a result of this, A ...

Masonite
Masonite board Back side of a masonite board Isorel, Quartrboard, Masonite Corporation, Masonite, also called Quartboard or pressboard, is a type of engineered wood made of steam-cooked and pressure-molded wood or paper fibers. The fibers form a stiff, dense material in a range of weights. The process was formulated and patented by American inventor William H. Mason. Masonite has been widely used in traditional school and office products such as spiral-bound notebooks and three-ring binders, but its unique physical characteristics lend themselves readily to a variety of end-uses, including (but not limited to) document storage, filing supplies (classification and file folders), report covers, folding cartons, tags, labels, and industrial applications. History In 1898, a product resembling Masonite ( hardboard) was first made in England by hot-pressing waste paper.Akers, 1966, p. x In 1924, Masonite was patented in Laurel, Mississippi, by William H. Mason, who was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hardboard
Hardboard, also called high-density fiberboard (HDF), is a type of fiberboard, which is a ''pressed wood'' or ''engineered wood'' product. It is used in furniture and in the construction industry. Description Hardboard is similar to particle board and medium-density fiberboard, but is density, denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed. The density of hardboard is higher than , usually about . It differs from particle board and medium-density fiberboard in that the bonding of the wood fibers requires no additional adhesive, the original lignin in the wood fibers sufficing to bond the hardboard together, although resin is often added. Hardboard is produced in either a wet or dry process. The wet process, known as the Mason Method, leaves one smooth side and one textured side as a wire mesh is used to allow moisture to escape. Dry processed hardboard is smooth on both sides. Masonite is produced using the wet p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Turpentine
Turpentine (which is also called spirit of turpentine, oil of turpentine, terebenthine, terebenthene, terebinthine and, colloquially, turps) is a fluid obtainable by the distillation of resin harvested from living trees, mainly pines. Principally used as a specialized solvent, it is also a source of material for Organic synthesis, organic syntheses. Turpentine is composed of terpenes, primarily the monoterpenes alpha-Pinene, alpha- and beta-Pinene, beta-pinene, with lesser amounts of carene, camphene, limonene, and terpinolene.Kent, James A. ''Riegel's Handbook of Industrial Chemistry'' (Eighth Edition) Van Nostrand Reinhold Company (1983) p.569 Nowadays, turpentine is rarely the product of distillation of pine resin, but is a byproduct of pulping. Pulping is achieved by two processes, the Kraft process and the sulfite process. The turpentines obtained from these two processes differ in their chemical compositions. The sulfite process gives a product that is rich in cymene, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Prussian Blue
Prussian blue (also known as Berlin blue, Brandenburg blue, Parisian and Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the chemical formula . It consists of cations, where iron is in the oxidation state of +3, and anions, where iron is in the oxidation state of +2, so, the other name of this salt is iron(III) hexacyanoferrate(II). Turnbull's blue is essentially identical chemically, excepting that it has different impurities and particle sizes—because it is made from different reagents—and thus it has a slightly different color. Prussian blue was created in the early 18th century and is the first modern chemical synthesis, synthetic pigment. It is prepared as a very fine colloidal dispersion, because the compound is not soluble in water. It contains variable amounts of other ions and its appearance depends sensitively on the size of the colloidal particles. The pigment is used in paints, it became prominent in 19th-century ...
