Johann Jacob Diesbach
Johann Jacob Diesbach () (born around 1670 – died in 1748), also written as Johann Jacob von Diesbach, was a Swiss pigment and dye producer known for first synthesizing a blue pigment known as Prussian blue (i.e. iron blue or Berlin blue). Biography Diesbach was from a noble family in Bern, Switzerland, who arrived in Berlin, Germany around 1701. Between 1704 and 1706, Diesbach was working as a paint manufacturer in Berlin. He was using an extract of crushed cochineal insects, iron sulphate and potash to create cochineal red lake. One batch of the product unexpectedly turned pale pink. When he tried to concentrate the mixture, it turned purple, then deep blue. He sought out the seller of the potash, Johann Konrad Dippel, an alchemist. Together, they realized that the reaction had occurred because the potash had been contaminated with bone oil. Neither Diesbach nor Dippel knew what exactly happened chemically, they had inadvertently created the first modern synthetic pigment. ...

Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. 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. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. 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.

Alchemy
Alchemy (from Arabic: ''al-kīmiyā''; from Ancient Greek: χυμεία, ''khumeía'') is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practiced in China, India, the Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Greco-Roman Egypt during the first few centuries AD.Principe, Lawrence M. The secrets of alchemy'. University of Chicago Press, 2012, pp. 9–14. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble metals" (particularly gold); the creation of an elixir of immortality; and the creation of panaceas able to cure any disease. The perfection of the human body and soul was thought to result from the alchemical ''magnum opus'' ("Great Work"). The concept of creating the philosophers' stone was variously connected with all of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
17th-century Chemists
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily k ...

18th-century German Male Artists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

Gottfried Wilhelm Leibniz
Gottfried Wilhelm (von) Leibniz . ( – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat. He is one of the most prominent figures in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history and philology. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. In addition, he contributed to the field of library science: while serving as overseer of the Wolfenbüttel library in Germany, he devised a cataloging system that would have served as a guide for many of Europe's largest libraries. Leibniz's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters and in unpublished manuscripts. He wrote in several languages, primarily in Latin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dippel's Oil
Dippel's oil (sometimes referred to as bone oil) is a nitrogenous by-product of the destructive distillation of bones. A dark, viscous, tar-like liquid with an unpleasant smell, it is named after its inventor, Johann Konrad Dippel. The oil consists mostly of aliphatic chains, with nitrogen functionalities and includes species such as pyrroles, pyridines and nitriles, as well as other nitrogenous compounds. Dippel's oil had a number of uses which are now mostly obsolete. Its primary use was as an animal and insect repellent. It saw limited use as a chemical warfare harassing agent during the desert campaign of World War II. The oil was used to render wells undrinkable and thus deny their use to the enemy. By not being lethal, the oil was claimed to not be in breach of the Geneva Protocol. See also * Neatsfoot oil, another bone-derived oil * Bone char Bone char ( lat, carbo animalis) is a porous, black, granular material produced by charring animal bones. Its composition vari ...

Johann Konrad Dippel
Johann Konrad Dippel, also spelled Johann Conrad Dippel (10 August 1673 – 25 April 1734), was a German Pietist theologian, physician, alchemist and occultist. Life Dippel was born at Castle Frankenstein near Mühltal and Darmstadt, and therefore once at his school the addendum ''Franckensteinensis'' and once at his university the addendum ''Franckensteina-Strataemontanus'' was used. He studied theology, philosophy and alchemy at the University of Giessen, obtaining a master's degree in theology in 1693. He published many theological works under the name Christianus Demócritus, and most of them are still preserved. Circa 1700, he turned to Hermetic studies and alchemy as a key to nature. Between 1700 and 1702, he engaged in a bitter dispute with the Reformed Court Preacher Conrad Broeske in Offenbach, with whom he shared millenarian hopes for soon-coming renewal in Christendom. He accused Broeske of compromise and collusion with the authorities after Broeske refused to publis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian Blue
Prussian blue (also known as Berlin blue, Brandenburg blue or, in painting, Parisian or Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the chemical formula Fe CN)">Cyanide.html" ;"title="e(Cyanide">CN) Turnbull's blue is chemically identical, but is made from different reagents, and its slightly different color stems from different impurities and particle sizes. Prussian blue was the first modern synthetic pigment. It is prepared as a very fine colloidal dispersion, because the compound is not soluble in water. It contains variable amounts of other ions and its appearance depends sensitively on the size of the colloidal particles. The pigment is used in paints, and it is the traditional "blue" in blueprints, and became prominent in 19th-century () Japanese woodblock prints. In medicine, orally administered Prussian blue is used as an antidote for certain kinds of heavy metal poisoning, e.g., by thallium(I) and radioactive is ...
