Claude-Fortuné 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 composi ...

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. Salammoniac is also the archaic name for the chemical compound ammonium chloride. History 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. Neverthele ...

Blue Vitriol
Copper(II) sulfate 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, while its anhydrous form is white. 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. Preparation and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verdigris
Verdigris () is a common name for any of a variety of somewhat toxic copper salt (chemistry), salts of acetic acid, which range in colour from green to a blue-green, bluish-green depending on their chemical composition.H. Kühn, Verdigris and Copper Resinate, in Artists' Pigments. A Handbook of Their History and Characteristics, Vol. 2: A. Roy (Ed.) Oxford University Press 1993, p. 131 – 158 Once used as a medicine and pharmaceutical preparation, verdigris occurs naturally, creating a patina on copper, bronze, and brass, and is the main component of a historic green pigment used for artistic purposes from antiquity until the late 20th century, including in Easel, easel painting, polychromatic sculptures, and illumination of maps. However, due to its instability, its popularity declined as other green pigments became readily available. The instability of its appearance stems from its Hydration number, hydration level and Base (chemistry), basicity, which change as the pigment inte ...

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 ease ...
