Crayon
A crayon (or wax pastel) is a stick of pigmented wax used for writing or drawing. Wax crayons differ from pastels, in which the pigment is mixed with a dry binder such as gum arabic, and from oil pastels, where the binder is a mixture of wax and oil. Crayons are available in a range of prices, and are easy to work with. They are less messy than most paints and markers, blunt (removing the risk of sharp points present when using a pencil or pen), typically non-toxic, and available in a wide variety of colors. These characteristics make them particularly good instruments for teaching small children to draw in addition to being used widely by student and professional artists. Composition In the modern English-speaking world, the term crayon is commonly associated with the standard wax crayon, such as those widely available for use by children. Such crayons are usually approximately in length and made mostly of paraffin wax. Paraffin wax is heated and cooled to achieve the corre ...

Colin Snedeker
Colin M. Snedeker (January 5, 1936 – October 22, 2016) was a British-born American chemist best known as the inventor of the first washable crayons. Snedeker developed the washable crayon while working as a chemist for Binney & Smith, which was the parent company of Crayola crayons at the time, in response to complaints from parents and consumers. He won the patent for the washable solid marking composition utilized in the crayons in 1990. He also developed products for Kiwi shoe polish and DuPont. Biography Snedeker was born in Newcastle upon Tyne in North East England on January 5, 1936. His grandfather had been killed in a fire before he was born and an English couple had adopted Snedeker's father when he was 13-years old. Colin Snedeker and his sister, Ann, were raised in England. They discovered letters from their father's birth family, who lived in Pennsylvania, in 1948, and soon were invited to visit them in the United States. Colin Snedeker entered high school at age ...

Conté
Conté (), also known as Conté sticks or Conté crayons, are a drawing medium composed of compressed powdered graphite or charcoal mixed with a clay base, square in cross-section. They were invented in 1795 by Nicolas-Jacques Conté, who created the combination of clay and graphite in response to the shortage of graphite caused by the Napoleonic Wars (when the British naval blockade of France prevented import). Conté crayons had the advantage of being cost-effective to produce, and easy to manufacture in controlled grades of hardness. They are now manufactured using natural pigments (iron oxides, carbon black, titanium dioxide), clay (kaolin), and a binder (cellulose ether). Conté crayons are most commonly found in black, white, and sanguine tones, as well as bistre, shades of grey, and other colors. Colors sets are especially useful for field studies and color studies. Some artists create entire paintings with them, using them more like pastels than like a drawing med ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Binney
Edwin Binney (November 24, 1866 – December 17, 1934) was an American entrepreneur and inventor, who created the first dustless white chalk, and along with his cousin C. Harold Smith (born London, 1860 - died, 1931), was the founder of handicrafts company "Binney and Smith", which marketed his invention of the Crayola crayon. The Binney family lived in Old Greenwich, Connecticut, as well as Fort Pierce, Florida. Biography Binney was born in Shrub Oak, New York. In 1866, he took control of his father's business, Peekskill Chemical Co. While experimenting with a mixture of slate waste, cement, and talc, Binney created the first dustless white chalk. The invention was awarded a gold medal at the St. Louis World's Fair in 1904. Co-founding the firm "Binney & Smith", he produced the first box of 'Crayola' crayons in 1903. His wife created the portmanteau name of the brand by combining elements of two words: ''craie'' (French for "chalk") and ''ola'' for "oleaginou" or "oily", since ...

Oil Pastel
An oil pastel is a painting and drawing medium formed into a stick which consists of pigment mixed with a binder mixture of non-drying oil and wax. They differ from other pastel sticks which are made with a gum or methyl cellulose binder, and from wax crayons which are made without oil. The surface of an oil pastel painting is less powdery than one made from gum pastels, but more difficult to protect with a fixative. Oil pastels are bold and bright. They can be blended easily but they can break easily too. History At the end of World War I, Kanae Yamamoto proposed an overhaul of the Japanese education system. He thought that it had been geared too much towards uncritical absorption of information by imitation and wanted to promote a less restraining system, a vision he expounded in his book ''Theory of self-expression'' which described the ''Jiyu-ga'' method, "learning without a teacher". Teachers Rinzo Satake and his brother-in-law Shuku Sasaki read Yamamoto's work and be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastel
A pastel () is an art medium in a variety of forms including a stick, a square a pebble or a pan of color; though other forms are possible; they consist of powdered pigment and a binder. The pigments used in pastels are similar to those used to produce some other colored visual arts media, such as oil paints; the binder is of a neutral hue and low saturation. The color effect of pastels is closer to the natural dry pigments than that of any other process. Pastels have been used by artists since the Renaissance, and gained considerable popularity in the 18th century, when a number of notable artists made pastel their primary medium. An artwork made using pastels is called a pastel (or a pastel drawing or pastel painting). ''Pastel'' used as a verb means to produce an artwork with pastels; as an adjective it means pale in color. Pastel media Pastel sticks or crayons consist of powdered pigment combined with a binder. The exact composition and characteristics of an individ ...

Gum Arabic
Gum arabic, also known as gum sudani, acacia gum, Arabic gum, gum acacia, acacia, Senegal gum, Indian gum, and by other names, is a natural gum originally consisting of the hardened sap of two species of the ''Acacia'' tree, ''Senegalia senegal'' and '' Vachellia seyal.'' The term "gum arabic" does not legally indicate a particular botanical source, however. The gum is harvested commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, so retained its name. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft-drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient in ...

Paraffin Wax
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately , and its boiling point is above . Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons. It is distinct from kerosene and other petroleum products that are sometimes called paraffin. Un-dyed, unscented paraffin candles are odorless and bluish-white. Paraffin wax was first created by Carl Reichenbach in Germany in 1830 and marked a major advancement in candlemaking technology, as it burned more cleanly and reliably than tallow candles and was cheaper to produce. In chemistry, ''paraffin'' is used synonymously with ''alkane'', indicating hydrocarbons with the general formula C''n''H2''n''+2. The name is derived from Latin ''par ...

Stationery
Stationery refers to commercially manufactured writing materials, including cut paper, envelopes, writing implements, continuous form paper, and other office supplies. Stationery includes materials to be written on by hand (e.g., letter paper) or by equipment such as computer printers. History of stationery Originally, the term 'stationery' referred to all products sold by a stationer, whose name indicated that his book shop was on a fixed spot. This was usually somewhere near a university, and permanent, while medieval trading was mainly carried on by itinerant peddlers (including chapmen, who sold books) and others (such as farmers and craftsmen) at markets and fairs. It was a unique term used between the 13th and 15th centuries in the manuscript culture. Stationers' shops were places where books were bound, copied, and published. These shops often loaned books to nearby university students for a fee. The books were loaned out in sections, allowing students to study or co ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
