Burnt Umber
Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary among shades of yellow, red, and green. Umber is considered one of the oldest pigments known to humans, first used in the Ajanta Caves from 200 BC to 600 AD. Umber's advantages are its highly versatile color, warm tone, and quick drying abilities. While some sources indicate that umber's name comes from its geographic origin in Umbria, other scholars suggest that it derives from the Latin word ''umbra'', which means "shadow". The belief that its name derives from the word for shadow is fitting, as the color helps create shadows. The color is primarily produced in Cyprus. Umber is typically mined from open pits or underground mines and ground into a fine powder that is washed to remove impurities. In the 20th century, the rise of synthetic dyes decreased the demand for natural pigments such as umber. History The earliest documented uses of umber date ...

Lascaux II
Lascaux ( , ; , "Lascaux Cave") is a network of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations. With continued debate, the age of the paintings is now usually estimated at around 17,000 to 22,000 years (early Magdalenian). Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the '' Prehistoric Sites and Decorated Caves of the Vézère Valley''. The original caves have been closed to the public since 1963, as their condition was quickly deteriorating, but there are now a number of replicas. History since rediscovery On 12 September 1940, the entrance to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Jan Blockx
Jan Blockx (25 January 1851 – 26 May 1912) was a Belgian composer, pianist and teacher. He was a leader of the Flemish nationalist school in music. Biography Born in Antwerp, Blockx studied the piano with Frans Aerts, the organ with Joseph Callaerts and composition with Peter Benoît at the Antwerp Conservatory. When he was still a student he wrote some songs, in Flemish, which became popular. However, his musical education studies were quite irregular, and he was essentially self-taught. Later he studied with Carl Reinecke at Leipzig. Despite the fact that he was Benoit's favorite pupil, Blockx wanted to make his own way in life, independent of his teacher and the Flemish Movement. Unlike Benoit, Blockx never intended his works to have the educational, uplifting effect that was typical for the Flemish Movement. This caused tensions between student and master: despite the fact that Blockx's work helped to spread Flemish music across the Belgian borders and even saved the ...

Antonio Palomino
Acislo Antonio Palomino de Castro y Velasco (165513 April 1726) was a Spanish painter of the Baroque period, and a writer on art, author of ''El Museo pictórico y escala óptica'', which contains a large amount of important biographical material on Spanish artists. Life Antonio Palomino was born to a respectable family at Bujalance, near Córdoba in 1655. He studied philosophy, theology and law at Córdoba, and had lessons in painting from Juan de Valdés Leal, who visited there in 1672, and afterwards from Juan de Alfaro y Gamez in 1675. After taking minor orders Palomino moved to Madrid in 1678, where he associated with Alfaro, Claudio Coello, and Juan Carreño de Miranda, and executed some indifferent frescoes. He soon afterwards married a lady of rank, and, having been appointed ''alcalde'' of the ''mesta'', was himself ennobled; in 1688 he was appointed painter to King Charles II.The artist visited Valencia in 1697 and remained there for three or four years, dev ...

Shades Of Green
Varieties of the color green may differ in hue, colorfulness, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Core definitions of green Green (sRGB) The color defined as ''green'' in the SRGB, sRGB color space is approximately the most Colorfulness#Chroma, chromatic green that can be reproduced on an average computer screen, and is the color named ''green'' in X11 color names, X11. It is one of the three primary colors used in the sRGB color space along with red and blue.

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 ...

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''.

Natural Pigment
A pigment is a powder used to add or alter color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year. Physical principles Like all materials, the color of pigments arises because they absorb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Dyes
A Colourant, colorant is any substance that changes the spectral transmittance or reflectance of a material. Synthetic colorants are those created in a laboratory or industrial setting. The production and improvement of colorants was a driver of the early synthetic chemical industry, in fact many of today's largest chemical producers started as dye-works in the late 19th or early 20th centuries, including Bayer AG (1863). Synthetics are extremely attractive for industrial and aesthetic purposes as they have they often achieve higher intensity and Colour fastness, color fastness than comparable natural pigments and dyes used since ancient times. Market viable large scale production of dyes occurred nearly simultaneously in the early major producing countries Britain (1857), France (1858), Germany (1858), and Switzerland (1859), and expansion of associated chemical industries followed. The mid-nineteenth century through WWII saw an incredible expansion of the variety and scale of manuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
