Pastel
A pastel () is an art medium that consists of powdered pigment and a binder (material), binder. It can exist in a variety of forms, including a stick, a square, a pebble, and a pan of color, among other forms. 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 colorfulness, 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Pastel
An oil pastel is a Art medium, painting medium that consists of powdered pigment mixed with a binder (material), binder mixture of non-drying oil and wax. Oil pastel is a type of pastel. They differ from other pastels which are made with a gum (botany), 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 other pastels, but more difficult to protect with a fixative (drawing), fixative. The colors of oil pastels are highly Colorfulness#Saturation, saturated and bright. They can be blended easily but they can break easily too. History At the end of World War I, Kanae Yamamoto (artist), 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 ...

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 (material), 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woad
''Isatis tinctoria'', also called woad (), dyer's woad, dyer's-weed, or glastum, is a flowering plant in the family Brassicaceae (the mustard family) with a documented history of use as a blue dye and medicinal plant. Its genus name, ''Isatis'', derives from the ancient Greek word for the plant, . It is occasionally known as Asp of Jerusalem. Woad is also the name of a blue dye produced from the leaves of the plant. Woad is native to the steppe and desert zones of the Caucasus, Central Asia to Eastern Siberia and Western Asia but is now also found in South-Eastern and Central Europe and western North America. Since ancient times, woad was an important source of blue dye and was cultivated throughout Europe, especially in Western and Southern Europe. In medieval times, there were important woad-growing regions in England, Germany and France. Towns such as Toulouse became prosperous from the woad trade. Woad was eventually replaced by the more colourfast ''Indigofera tinctoria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light colour, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or sk ...

Art Medium
Media, or mediums, are the core types of material (or related other tools) used by an artist, composer, designer, etc. to create a work of art. For example, a visual artist may broadly use the media of painting or sculpting, which themselves have more specific media within them, such as watercolor paints or marble. The following is a list of artistic categories and the media used within each category: Architecture *Cement, concrete, mortar * Cob *Glass *Metal *Stone, brick *Wood Carpentry *Adhesives *Wood (timber) Ceramics *Bone china *Clay * Glaze *Porcelain *Pottery *Terracotta *Tile Drawing Common drawing materials *Acrylic paint *Chalk *Charcoal *Colored pencil *Conté *Crayon * Encaustic *Fresco *Glitter * Gouache *Graphite * Ink * Intaglio *Oil paint * Glass paint *Pastel *Pixel *Printmaking * Sketch *Tempera *Watercolor Common supports (surfaces) for drawing *Canvas *Card stock *Concrete *Fabric *Glass *Human body *Metal *Paper *Papyrus *Parchment *Plaste ...

Scenery Painter Schlosspark Charlottenburg Berlin 20080423
Theatrical scenery is that which is used as a setting for a theatrical production. Scenery may be just about anything, from a single chair to an elaborately re-created street, no matter how large or how small, whether the item was custom-made or is the genuine item, appropriated for theatrical use. History The history of theatrical scenery is as old as the theatre itself, and just as obtuse and tradition bound. What we tend to think of as 'traditional scenery', i.e. two-dimensional canvas-covered ' flats' painted to resemble a three-dimensional surface or vista, is a relatively recent innovation and a significant departure from the more ancient forms of theatrical expression, which tended to rely less on the actual representation of space and more on the conveyance of action and mood. By the Shakespearean era, the occasional painted backdrop or theatrical prop was in evidence, but the show itself was written so as not to rely on such items to convey itself to the audience.

Rottenstone
Rotten stone, sometimes spelled as rottenstone, also known as tripoli, is fine powdered porous rock (geology), rock used as a polishing abrasive for metal smithing, historically for the grinding of optical lenses and in woodworking. It is usually weathered limestone mixed with Diatomaceous earth, diatomaceous, amorphous, or crystalline silicon dioxide, silica. It has similar applications to pumice, but it is generally sold as a finer powder and used for a more glossy polish after an initial treatment with coarser pumice powder. Tripoli particles are rounded rather than sharp, making it a milder abrasive. It is usually mixed with oil, sometimes water, and rubbed on the surface of varnished or lacquered wood with a felt pad or cloth. Rotten stone is sometimes used to buff stains out of wood. Some polishing waxes contain powdered rotten stone in a paste substrate. For larger polishing jobs, rotten stone mixed with a binder is applied to polishing wheels. It has also been used to p ...

Gouache
Gouache (; ), body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a long history, having been used for at least twelve centuries. It is used most consistently by commercial artists for posters, illustrations, comics, and other design work. Gouache is similar to watercolor in that it can be rewetted and dried to a matte finish, and the paint can become infused into its paper support. It is similar to acrylic or oil paints in that it is normally used in an opaque painting style and it can form a superficial layer. Many manufacturers of watercolor paints also produce gouache, and the two can easily be used together. Description Gouache paint is similar to watercolor, but it is modified to make it opaque. Just as in watercolor, the binding agent has traditionally been gum arabic but since the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medieval Latin
Medieval Latin was the form of Literary Latin used in Roman Catholic Church, Roman Catholic Western Europe during the Middle Ages. It was also the administrative language in the former Western Roman Empire, Roman Provinces of Mauretania, Numidia (Roman province), Numidia and Africa (Roman province), Africa Proconsularis under the Vandals, the Exarchate of Africa, Byzantines and the Kingdom of Altava, Romano-Berber Kingdoms, until it declined after the Arab conquest of North Africa, Arab Conquest. Medieval Latin in Southern and Central Visigothic Kingdom, Visigothic Hispania, conquered by the Arabs immediately after North Africa, experienced a similar fate, only recovering its importance after the Reconquista by the Northern Christian Kingdoms. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned as the main medium of scholarly exchange, as the liturgical language of the Roman Catholic Church, Churc ...

Laid Paper
Laid paper is a type of paper having a ribbed texture imparted by the manufacturing process. In the pre-mechanical period of European papermaking (from the 12th century into the 19th century), laid paper was the predominant kind of paper produced. Its use, however, diminished in the 19th century, when it was largely supplanted by wove paper. Laid paper is still commonly used by artists as a support for charcoal drawings. Traditional production Before the mechanization of papermaking, paper was made by hand, using a wire sieve mounted in a rectangular mould to produce a single sheet at a time. A papermaker would dip the mould into a vat containing diluted pulp of hemp or linen fibers, then lift it out, tilt it to spread the pulp evenly over the sieve and, as the water drained out between the wires, shake the mould to lock the fibers together. In the process, the pattern of the wires in the sieve was imparted to the sheet of paper. Up until the invention of wove paper around 1756, ...

Saturation (color Theory)
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic (Any color that is absent of white, grey, or black)"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high ( Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area t ...

Poly(methyl Methacrylate)
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Walcast, Hesalite, Plexiglas, Acrylite, Lucite, PerClax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. It is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. History The first acrylic acid was created in 1843. Methacrylic acid, derived from acrylic acid, was formulated in 1865. The reaction between methacrylic acid and methanol results in the ester methyl methacrylate. It was developed in 1928 in several different la ...
