Manganese Violet
Manganese violet is the inorganic compound with the formula NH4MnP2O7.Hugo Müller, Wolfgang Müller, Manfred Wehner, Heike Liewald "Artists' Colors" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. As implied by its name and composition, it is a purple, inorganic pigment. Because it is often impure, the pigment's hue is varied. Notable artists who have used the pigment include Claude Monet, who relied on manganese violet in his Rouen Cathedral series to further his exploration of shadows. Beyond the artistic community, manganese violet has been used in cosmetics to color products like lipstick and eyeshadow. History The pigment was originally named Nurnberg violet, and little is known about its early history beyond its creation in 1866 by E. Leykeuf. The first documented production of the pigment was in 1890 by Messers Winsor and Newton (currently known as Winsor & Newton). In the Winsor & Newton 1892 catalog, both permanent violet and permanent mauv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inorganic Compound
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsthat is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep Mantle (geology), mantle remain active areas of investigation. All allotropes (structurally different pure forms of an element) and some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, graphene, etc.), carbon monoxide , carbon dioxide , carbides, and salt (chemistry), salts of inorganic anions such as carbonates, cyanides, cyanates, thiocyanates, isothiocyanates, etc. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it cannot occur within life, living things.

French Ultramarine
Ultramarine is a deep blue pigment which was originally made by grinding lapis lazuli into a powder. Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold. The name ultramarine comes from the Latin word . The word means 'beyond the sea', as the pigment was imported by Italian traders during the 14th and 15th centuries from mines in Afghanistan. Much of the expansion of ultramarine can be attributed to Venice which historically was the port of entry for lapis lazuli in Europe. Ultramarine was the finest and most expensive blue used by Renaissance painters. It was often used for the robes of the Virgin Mary and symbolized holiness and humility. It remained an extremely expensive pigment until a synthetic ultramarine was invented in 1826. Ultramarine is a permanent pigment when under ideal preservation conditions. Otherwise, it is susceptible to discoloration an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt Blue
Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminium(III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt(II) oxide-aluminium oxide, or cobalt(II) aluminate, CoAl2O4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue. It is extremely stable, and has historically been used as a coloring agent in ceramics (especially Chinese porcelain), jewelry, and paint. Transparent glasses are tinted with the silica-based cobalt pigment "smalt". Historical uses and production Ores containing cobalt have been used since antiquity as pigments to give a blue color to porcelain and glass. Cobalt blue in impure forms had long been used in Chinese porcelain. In 1742, Swedish chemist Georg Brandt showed that the blue color was due to a previously unidentified metal, cobalt. The first recorded use of ''cobalt blue'' as a color name in English was in 1777. It was independently discovered as an alumina ...

Georges Seurat
Georges Pierre Seurat ( , ; ; 2 December 1859 – 29 March 1891) was a French post-Impressionist artist. He devised the painting techniques known as chromoluminarism and pointillism and used conté crayon for drawings on paper with a rough surface. Seurat's artistic personality combined qualities that are usually thought of as opposed and incompatible: on the one hand, his extreme and delicate sensibility, on the other, a passion for logical abstraction and an almost mathematical precision of mind. His large-scale work '' A Sunday Afternoon on the Island of La Grande Jatte'' (1884–1886) altered the direction of modern art by initiating Neo-Impressionism, and is one of the icons of late 19th-century painting. Biography Family and education Seurat was born on 2 December 1859 in Paris, at 60 rue de Bondy (now rue René Boulanger). The Seurat family moved to 136 boulevard de Magenta (now 110 boulevard de Magenta) in 1862 or 1863. Seurat: p. 16 His father, Antoine Chrysost ...

Impressionism
Impressionism was a 19th-century art movement characterized by visible brush strokes, open Composition (visual arts), composition, emphasis on accurate depiction of light in its changing qualities (often accentuating the effects of the passage of time), ordinary subject matter, unusual visual angles, and inclusion of movement as a crucial element of human perception and experience. Impressionism originated with a group of Paris-based artists whose independent exhibitions brought them to prominence during the 1870s and 1880s. The Impressionists faced harsh opposition from the conventional art community in France. The name of the style derives from the title of a Claude Monet work, ''Impression, soleil levant'' (''Impression, Sunrise''), which provoked the critic Louis Leroy to coin the term in a Satire, satirical 1874 review of the First Impressionist Exhibition published in the Parisian newspaper ''Le Charivari''. The development of Impressionism in the visual arts was soon foll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monet
Oscar-Claude Monet (, ; ; 14 November 1840 – 5 December 1926) was a French painter and founder of Impressionism painting who is seen as a key precursor to modernism, especially in his attempts to paint nature as he perceived it. During his long career, he was the most consistent and prolific practitioner of Impressionism's philosophy of expressing one's perceptions of nature, especially as applied to '' ''plein air'''' (outdoor) landscape painting. The term "Impressionism" is derived from the title of his painting '' Impression, soleil levant'', which was exhibited in 1874 at the First Impressionist Exhibition, initiated by Monet and a number of like-minded artists as an alternative to the Salon. Monet was raised in Le Havre, Normandy, and became interested in the outdoors and drawing from an early age. Although his mother, Louise-Justine Aubrée Monet, supported his ambitions to be a painter, his father, Claude-Adolphe, disapproved and wanted him to pursue a career in bu ...

Édouard Manet
Édouard Manet (, ; ; 23 January 1832 – 30 April 1883) was a French Modernism, modernist painter. He was one of the first 19th-century artists to paint modern life, as well as a pivotal figure in the transition from Realism (art movement), Realism to Impressionism. Born into an upper-class household with strong political connections, Manet rejected the naval career originally envisioned for him; he became engrossed in the world of painting. His early masterworks, Le Déjeuner sur l'herbe, ''The Luncheon on the Grass'' (''Le déjeuner sur l'herbe'') and ''Olympia (Manet), Olympia'', premiering in 1863 and '65, respectively, caused great controversy with both critics and the Academy of Fine Arts, but soon were praised by progressive artists as the breakthrough acts to the new style, Impressionism. These works, along with others, are considered watershed paintings that mark the start of modern art. The last 20 years of Manet's life saw him form bonds with other great artists of ...

Stereochromy
Mineral painting or Keim's process, also known as stereochromy, is a mural or fresco painting technique that uses a water glass-based paint to maximize the lifetime of the finished work. The name "stereochromy" was first used in about 1825 by Johann Nepomuk von Fuchs and Schlotthaurer. In the original technique, pigments were applied to plaster or stone and sealed with water glass to preserve and enhance the colors. The method was then improved in the 1880s by Adolf Wilhelm Keim and renamed mineral paintingMayer, Ralph.

Fresco
Fresco ( or frescoes) is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting becomes an integral part of the wall. The word ''fresco'' () is derived from the Italian adjective ''fresco'' meaning "fresh", and may thus be contrasted with fresco-secco or secco mural painting techniques, which are applied to dried plaster, to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with Italian Renaissance painting. The word ''fresco'' is commonly and inaccurately used in English to refer to any wall painting regardless of the plaster technology or binding medium. This, in part, contributes to a misconception that the most geographically and temporally common wall painting technology was the painting into wet lime plaster. Even in apparently '' buon fresco'' technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
