Angelo Sala
Angelo Sala (Latin: Angelus Sala) (21 March 1576, Vicenza – 2 October 1637, Bützow) was an Italian doctor and early Iatrochemistry, iatrochemist. He promoted chemical remedies and, drawing on the relative merits of the conflicting chemical and Galenic corpus, Galenical systems of medicine, dismissed alchemical Nuclear transmutation, transmutation and 'universal medicine'; objected to Tartaric acid, tartar which had deliquesced being called an 'oil'; observed that metals reacted differently with acids; that Sulfur, sulphur extracted something from the air in order to burn; that silver nitrate darkened on exposure to light; surmised the existence of elementary (atomic) particles; and described newly discovered compounds and methods of preparation. Sala made the first studies on the formation of alcohol from fermenting musts and so is regarded as the founder of sugar chemistry. Biography Sala was the son of the Spinning wheel, spinner Bernardino Sala. He probably first learned t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John VIII, Count Of Nassau-Siegen
John VIII, Count of Nassau-Siegen (''Jan'' or ''Johan''; Dillenburg, 29 September 1583 – Ronse, 27 July 1638) was a German nobleman and militarist of the 17th century. Life John VIII, Count of Nassau-Siegen, Katzenelnbogen, Vianden and Dietz, Marquis of Monte-Caballo, Baron of Ronse and Beilstein, was the second son of John VII, Count of Nassau-Siegen and Countess Magdalene of Waldeck-Wildungen. He was educated in Herborn, Kassel and Geneva. In 1610 he participated in the Dutch States Army in the conquest of Jülich. On 25 December 1613, much to the horror of his family, he openly converted to Catholicism and entered in the service of the army of Charles Emmanuel I, Duke of Savoy. After the death of his elder brother, John Ernest in September 1617, he claimed his rights, but his father chose a Protestant successor. When his father died in 1623, John VIII occupied Nassau-Siegen at the head of a Habsburg Army and started the Contra-Reformation. In 1624 he became a Kn ...

Iron(III) Oxide
Iron(III) oxide or ferric oxide is the inorganic compound with the formula . It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry. It is also known as red iron oxide, especially when used in pigments. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (), which also occurs naturally as the mineral magnetite. Iron(III) oxide is often called rust, since rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as hydrous ferric oxide. Ferric oxide is readily attacked by even weak acids. It is a weak oxidising agent, most famously when reduced by aluminium in the thermite reaction. Structure can be obtained in various polymorphs. In the primary polymorph, α, iron adopts octahedral coordination geometry. That is, each Fe center is bound to six oxygen ligands. In t ...

Vitriol
Vitriol is the general chemical name encompassing a class of chemical compounds comprising sulfates of certain metalsoriginally, iron or copper. Those mineral substances were distinguished by their color, such as green vitriol for hydrated iron(II) sulfate and blue vitriol for hydrated copper(II) sulfate.Vitriol entry in the online Encyclopaedia Britannica. Accessed on 2020-08-28. These materials were found originally as crystals formed by evaporation of groundwater that percolated through minerals and collected in pools on the floors of old mines. The word ''vitriol'' comes from the Latin word ''vitriolus'', meaning "small glass", as those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paracelsianism
Paracelsianism (also Paracelsism; German: ') was an early modern medical movement based on the theories and therapies of Paracelsus. It developed in the second half of the 16th century, during the decades following Paracelsus's death in 1541, and it flourished during the first half of the 17th century, representing one of the most comprehensive alternatives to learned medicine, the traditional system of therapeutics derived from Galenic physiology. Based on the by then antiquated principle of maintaining harmony between the microcosm and macrocosm, Paracelsianism fell rapidly into decline in the later 17th century with the rise of the scientific movement, but left its mark on medical practices. It was responsible for the widespread introduction of mineral therapies and several other iatrochemical techniques. Most well known Paracelsians were men but some educated women engaged in paracelsian alchemy in both its spiritual-philosophical and medicinal aspects. Spagyric Spagyri ...

Philosopher's Stone
The philosopher's stone is a mythic alchemical substance capable of turning base metals such as mercury into gold or silver; it was also known as "the tincture" and "the powder". Alchemists additionally believed that it could be used to make an elixir of life which made possible rejuvenation and immortality. For many centuries, it was the most sought-after goal in alchemy. The philosopher's stone was the central symbol of the mystical terminology of alchemy, symbolizing perfection at its finest, divine illumination, and heavenly bliss. Efforts to discover the philosopher's stone were known as the Magnum Opus ("Great Work"). Antiquity The earliest known written mention of the philosopher's stone is in the ''Cheirokmeta'' by Zosimos of Panopolis (). Alchemical writers assign a longer history. Elias Ashmole and the anonymous author of ''Gloria Mundi'' (1620) claim that its history goes back to Adam, who acquired the knowledge of the stone directly from God. This knowledge ...

Ammonium Carbonate
Ammonium carbonate is a chemical compound with the chemical formula . It is an ammonium salt of carbonic acid. It is composed of ammonium cations and carbonate anions . Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and is a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and salt of hartshorn, and produces a pungent smell when baked. It comes in the form of a white powder or block, with a molar mass of 96.09 g/mol and a density of 1.50 g/cm3. It is a strong electrolyte. Production Ammonium carbonate is produced by combining carbon dioxide and aqueous ammonia. About 80,000 tons/year were produced as of 1997. : An orthorhombic ammonium carbonate monohydrate is known (). It crystallizes in an ammonia solution exposed in a carbon dioxide-rich atmos ...

Hydrochloric Acid
Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungency, pungent smell. It is classified as a acid strength, strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans. Hydrochloric acid is an important laboratory reagent and industrial chemical. Etymology Because it was produced from halite, rock salt according to the methods of Johann Rudolph Glauber, hydrochloric acid was historically called by European alchemists ''spirits of salt'' or ''acidum salis'' (salt acid). Both names are still used, especially in other languages, such as , , , , , , , , , , (''ensan''), zh, 盐酸 (''yánsuān''), and (''yeomsan''). Gaseous HCl was called ''marine acid air''. The name ''muriatic acid'' has the same origin (''muriatic'' means "pertaining to brine or salt", hence ''muriate'' means hydrochloride), and this ...

Salammoniac
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 ...

Alchemy
Alchemy (from the Arabic word , ) is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practised 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.. Greek-speaking alchemists often referred to their craft as "the Art" (τέχνη) or "Knowledge" (ἐπιστήμη), and it was often characterised as mystic (μυστική), sacred (ἱɛρά), or divine (θɛíα). 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
