Claude Ruggieri
Claude Ruggieri (1777 – 30 August 1841) was a pyrotechnician in Paris, France, who developed and wrote about innovations in fireworks design. He and others in his family were renowned and patronized by royalty for their creation of great fireworks extravaganzas. They also opened a public pleasure garden where fireworks displays could be enjoyed by the people of Paris. The Ruggieris introduced a style of fireworks that was theatrical rather than being based on military gunnery. Following a disastrous fireworks accident on 30 May 1770, the Ruggieris fell from favor. Claude-Fortuné Ruggieri was primarily responsible for restoring the family to its position of prominence. He used the new science of chemistry to develop novel fireworks, in particular colored fireworks that distinguished the Ruggieris from their rivals. He discovered a way to reliably create a vivid "green fire" observed in Russian fireworks. In his writings, Claude Ruggieri discussed "aerial philosophy", the compos ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Louis XVIII
Louis XVIII (Louis Stanislas Xavier; 17 November 1755 – 16 September 1824), known as the Desired (), was King of France from 1814 to 1824, except for a brief interruption during the Hundred Days in 1815. He spent twenty-three years in exile: during the French Revolution and the First French Empire (1804–1814), and during the Hundred Days. Until his accession to the throne of France, he held the title of Count of Provence as brother of King Louis XVI. On 21 September 1792, the National Convention abolished the monarchy and deposed Louis XVI, who was later executed by guillotine. When his young nephew Louis XVII died in prison in June 1795, the Count of Provence proclaimed himself (titular) king under the name Louis XVIII. Following the French Revolution and during the Napoleonic era, Louis XVIII lived in exile in Prussia, England, and Russia. When the Sixth Coalition finally defeated Napoleon in 1814, Louis XVIII was placed in what he, and the French royalists, co ...

Sal-ammoniac
Salammoniac, also sal ammoniac or salmiac, is a rare naturally occurring mineral composed of ammonium chloride, NH4Cl. It forms colorless, white, or yellow-brown crystals in the isometric-hexoctahedral class. It has very poor cleavage and is brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and it has a low specific gravity of 1.5. It is water-soluble. Sal ammoniac is also the archaic name for the chemical compound ammonium chloride. Pliny, in Book XXXI of his '' Natural History'', refers to a salt produced in the Roman province of Cyrenaica named ''hammoniacum'', so called because of its proximity to the nearby Temple of Jupiter Amun (Greek Ἄμμων ''Ammon''). However, the description Pliny gives of the salt does not conform to the properties of ammonium chloride. According to Herbert Hoover's commentary in his English translation of Georgius Agricola's '' De re metallica'', it is likely to have been common sea salt. In any case, tha ...

Blue Vitriol
Copper(II) sulfate, also known as copper sulphate, is an inorganic compound with the chemical formula . It forms hydrates , where ''n'' can range from 1 to 7. The pentahydrate (''n'' = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate. Older names for the pentahydrate include blue vitriol, bluestone, vitriol of copper,Antoine-François de Fourcroy, tr. by Robert Heron (1796) "Elements of Chemistry, and Natural History: To which is Prefixed the Philosophy of Chemistry". J. Murray and others, Edinburgh. Page 348. and Roman vitriol.Oxford University Press,Roman vitriol, Oxford Living Dictionaries. Accessed on 2016-11-13 It exothermically dissolves in water to give the aquo complex , which has octahedral molecular geometry. The structure of the solid pentahydrate reveals a polymeric structure wherein copper is again octahedral but bound to four water ligands. The centers are interconnected by sulfate anions to form chains. Anhydrous copper sulf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verdigris
Verdigris is the common name for blue-green, copper-based pigments that form a patina on copper, bronze, and brass. The technical literature is ambiguous as to its chemical composition. Some sources refer to "neutral verdigris" as copper(II) acetate monohydrate () and to "blue verdigris" as . Another source describes it as a basic copper carbonate (()2), and, when near the sea, basic copper chloride (Cu2(OH)3Cl). Still other sources describe verdigris as .(Cu(OH)2)n where n varies from 0 to 3. The alchemical symbol for verdigris is 🜨 (unicode U+1F728). Etymology The name ''verdigris'' comes from the Middle English ''vertegrez'', from the Old French ''verte grez'', meaning ''vert d'aigre'', "green ade by action ofvinegar". The modern French writing of this word is ''vert-de-gris'' ("green of grey"), sounding like the older name ''verdet gris'' ("grey greenish"), itself a deformation of ''verte grez''. It was used as a pigment in paintings and other art objects (as green col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Lavoisier
Antoine-Laurent de Lavoisier ( , ; ; 26 August 17438 May 1794), When reduced without charcoal, it gave off an air which supported respiration and combustion in an enhanced way. He concluded that this was just a pure form of common air and that it was the air itself "undivided, without alteration, without decomposition" which combined with metals on calcination. After returning from Paris, Priestley took up once again his investigation of the air from mercury calx. His results now showed that this air was not just an especially pure form of common air but was "five or six times better than common air, for the purpose of respiration, inflammation, and ... every other use of common air". He called the air dephlogisticated air, as he thought it was common air deprived of its phlogiston. Since it was therefore in a state to absorb a much greater quantity of phlogiston given off by burning bodies and respiring animals, the greatly enhanced combustion of substances and the greater e ...

Indigo
Indigo is a deep color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine, based on the ancient dye of the same name. The word "indigo" comes from the Latin word ''indicum'', meaning "Indian", as the dye was originally exported to Europe from India. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between blue and violet; however, sources differ as to its actual position in the electromagnetic spectrum. The first known recorded use of indigo as a color name in English was in 1289. History ''Indigofera tinctoria'' and related species were cultivated in East Asia, Egypt, India, Bangladesh and Peru in antiquity. The earliest direct evidence for the use of indigo dates to around 4000 BC and comes from Huaca Prieta, in contemporary Peru. Pliny the Elder mentions India as the source of the dye after which it was named. It was importe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Antoinette
Marie Antoinette Josèphe Jeanne (; ; née Maria Antonia Josepha Johanna; 2 November 1755 – 16 October 1793) was the last queen of France before the French Revolution. She was born an archduchess of Austria, and was the penultimate child and youngest daughter of Empress Maria Theresa and Emperor Francis I. She became dauphine of France in May 1770 at age 14 upon her marriage to Louis-Auguste, heir apparent to the French throne. On 10 May 1774, her husband ascended the throne as Louis XVI and she became queen. Marie Antoinette's position at court improved when, after eight years of marriage, she started having children. She became increasingly unpopular among the people, however, with the French ''libelles'' accusing her of being profligate, promiscuous, allegedly having illegitimate children, and harboring sympathies for France's perceived enemies—particularly her native Austria. The false accusations of the Affair of the Diamond Necklace damaged her reputation further ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis XVI
Louis XVI (''Louis-Auguste''; ; 23 August 175421 January 1793) was the last King of France before the fall of the monarchy during the French Revolution. He was referred to as ''Citizen Louis Capet'' during the four months just before he was executed by guillotine. He was the son of Louis, Dauphin of France, son and heir-apparent of King Louis XV, and Maria Josepha of Saxony. When his father died in 1765, he became the new Dauphin. Upon his grandfather's death on 10 May 1774, he became King of France and Navarre, reigning as such until 4 September 1791, when he received the title of King of the French, continuing to reign as such until the monarchy was abolished on 21 September 1792. The first part of his reign was marked by attempts to reform the French government in accordance with Enlightenment ideas. These included efforts to abolish serfdom, remove the ''taille'' (land tax) and the ''corvée'' (labour tax), and increase tolerance toward non-Catholics as well as aboli ...

Muhammad Ali Of Egypt
Muhammad Ali Pasha al-Mas'ud ibn Agha, also known as Muhammad Ali of Egypt and the Sudan ( sq, Mehmet Ali Pasha, ar, محمد علي باشا, ; ota, محمد علی پاشا المسعود بن آغا; ; 4 March 1769 – 2 August 1849), was the Albanian Ottoman governor and de facto ruler of Egypt from 1805 to 1848, considered the founder of modern Egypt. At the height of his rule, he controlled all of Egypt, Sudan, Hejaz and the Levant. He was a military commander in an Albanian Ottoman force sent to recover Egypt from a French occupation under Napoleon. Following Napoleon's withdrawal, Muhammad Ali rose to power through a series of political maneuvers, and in 1805 he was named '' Wāli'' (viceroy) of Egypt and gained the rank of Pasha.
