Cobalt blue pigment

Blue pigments are natural or synthetic materials, usually made from minerals and insoluble with water, used to make the blue colors in painting and other arts. The raw material of the earliest blue pigment was lapis lazuli from mines in Afghanistan, that was refined into the pigment ultramarine. Since the late 18th and 19th century, blue pigments are largely synthetic, manufactured in laboratories and factories.

Ultramarine was historically the most prestigious and expensive of blue pigments. It was produced from lapis lazuli, a mineral whose major source was the mines of Sar-e-Sang in what is now northeastern Afghanistan.[1] It was transformed into a pigment by the Afghans beginning in about the 5th century, and exported by caravans to India. It was the most expensive blue used by Renaissance artists. It was often reserved for special purposes, such as painting the robes of the Virgin Mary.[2] Johannes Vermeer used ultramarine only for the most important surfaces where he wanted to attract attention. Pietro Perugino, in his depiction of the Madonna and Child on the Certosa de Pavio Altarpiece, painted only the top level of the Virgin's robes in ultramarine, with azurite beneath.[3]

Ultramarine became more widely used after its successful synthesis in the 19th century, which reduced its price substantially. In 1814, a French chemist named Tassaert observed the spontaneous formation of a blue compound, very similar to ultramarine, in a lime kiln at St. Gobain. In 1824, the Societé pour l'Encouragement d'Industrie offered a prize for the artificial production of the precious color. Processes were devised independently by Jean Baptiste Guimet (1826) and Christian Gmelin (1828); while Guimet kept his process a secret, Gmelin published his, and thus became the originator of the French synthetic ultramarine industry. At the beginning of the 19th century, the price of a kilogram of lapis lazuli was between six and ten thousand francs. The price of artificial ultramarine was less than eight hundred francs per kilogram.[4] Synthetic ultramarine was widely appreciated by the French impressionists, and Vincent van Gogh used both French ultramarine and cobalt blue for his painting The Starry Night (1889).[5]


الأزرق المصري

الأزرق المصري كان أول صبغة زرقاء اصطناعية. It was made from a mixture of silica, lime, copper, and an alkali. It was widely used in The Fourth Dynasty of ancient Egypt (c. 2613 to 2494 BC).[6] Egyptian blue is responsible for the blue colour seen very commonly in Egyptian faience.

أزرق الهان

أزرق الهان (also called Chinese blue) is a synthetic barium copper silicate pigment used in ancient and imperial China from the Western Zhou period (1045–771 BC) until the end of the Han dynasty (circa 220 AD). Han blue and the chemically related Han purple were used to decorate hu vessels during the Han dynasty, and were also used for mural paintings in tombs of the same period.[7]

أزرق المايا

أزرق المايا is a synthetic turquoise-blue pigment made by infusing indigo dyes (particularly those derived from the anil shrub) into palygorskite, a clay that binds and stabilises the indigo such that it becomes resistant to weathering.[8] Developed in Mesoamerica in the first millennium AD, it saw wide use in the region, most prominently in the art of the Maya civilisation. It is known on media from pottery to murals to codices, and also played an important role in ritual sacrifices of both objects and people: silt at the bottom of the Sacred Cenote at Chichén Itzá is heavily stained with Maya blue, washed off the hundreds of sacrificial offerings cast into the cenote during the city's occupation.[9] Maya blue continued to be used into the Spanish colonial period; though falling out of widespread use in the Maya region during the 16th century, some areas apparently continued to produce it for export, as Cuban colonial paintings of the 18th and 19th century have been found to make use of Maya blue probably imported from Campeche.[10]

أزوريت

صبغة الأزوريت is derived from the soft, deep-blue copper mineral of the same name, which forms from the weathering of copper ore deposits. It was mentioned in Pliny the Elder's Natural History under the Greek name kuanos (κυανός: "deep blue," root of English cyan) and the Latin name caeruleum. The modern English name of the mineral reflects this association, since both azurite and azure are derived via Arabic from the Persian lazhward (لاژورد), an area known for its deposits of another deep-blue stone, لازورد. Azurite was often used in the Renaissance and later as a less expensive substitute for ultramarine. Lower layers would be painted in azurite, with the most visible portions painted in ultramarine. The drawback of the pigment is that it degrades and darkens over time.[11]

أزرق پروسيا

أزرق پروسيا is a dark blue pigment containing iron and cyanide produced by the oxidation of ferrous ferrocyanide salts. It was invented in Berlin between 1704 and 1710. It had an immediate impact on the pigment market, because its intense deep blue color approached the quality of ultramarine at a much lower price. It was widely adapted by major European artists, notably Thomas Gainsborough and Canaletto, who used it to paint the Venetian sky.[12] It was also used by Japanese artists, including هوكوساي, for the deeper blues of waves.

Cerulean blue

Cerulean blue was created in 1789 by the Swiss chemist Albrecht Höpfner.[13] Subsequently, there was a limited German production under the name of Cölinblau. The primary chemical constituent of the pigment is cobalt(II) stannate (Co 2SnO 4).[14]

أزرق الكوبالت

أزرق الكوبالت is a synthetic blue pigment was invented in 1803 as a rival to ultramarine. It was made by the process of sintering, that is by compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. It combined cobalt(II) oxide with aluminum(III) oxide (alumina) at 1200 °C. It was also used as colorant, particularly in blue glass and as the blue pigment used for centuries in Chinese blue and white porcelain, beginning in the late eighth or early ninth century.[15]

Cobalt glass, or Smalt, is a variation of cobalt blue. It is made of ground blue potassium glass containing cobalt blue. It was widely used in painting in the 16th and the 17th centuries. Smalt was popular because of its low cost; it was widely used by Dutch and Flemish painters, including Hans Holbein the Younger.[16]

أزرق الإتريوم والإنديوم والمنجنيز

أزرق اليين من هو صبغة غير عضوية ذات لون أزرق شديد الزرقة اكتشفها Mas Subramanian and his graduate student, Andrew Smith, at Oregon State University in 2009.[17][18] It has been used in water, oil and acrylic paints from paint vendors including Derivan,[19][20] Golden[21] and Gamblin.[22]

The name ”YInMn” comes from the chemical symbols for yttrium, indium and manganese. The intense blue color comes from the crystal structure of the chemical compound, and can be varied by adjusting the ratio of indium and manganese. After discovering this pigment, Subramanian’s research team has used similar principles of colour science to designed a range of novel green, purple, and orange pigments.[23][24][25]
