Kermesite
Kermesite or antimony oxysulfide is also known as red antimony (Sb2S2O) . The mineral's color ranges from cherry red to a dark red to a black. Kermesite is the result of partial oxidation between stibnite (Sb2S3) and other antimony oxides such as valentinite (Sb2O3) or stibiconite (Sb3O6(OH)). Under certain conditions with oxygenated fluids the transformation of all sulfur to oxygen would occur but kermesite occurs when that transformation is halted. Mining and specimens Deposits of this mineral have been found all over the world, however notable deposits have been found in Braunsdorf, near Freiberg, Saxony, Germany; Pernek, Pezinok, and Pribram, Czechoslovakia; the Lac Nicolet mine, South Ham Township, Wolfe County, Quebec, Canada; Sombrerete, Zacatecas, Mexico; Santa Cruz and San Francisco mines, Poopo, Oruro, Bolivia; Que Que, Zimbabwe; Djebel Haminate, Algeria; Broken Hill, New South Wales, Australia; Mohave, Kern County, California and Burke, Shoshone County, Idaho.

Valentinite
Valentinite is an antimony oxide mineral with formula Sb2 O3. Valentinite crystallizes in the orthorhombic system and typically forms as radiating clusters of euhedral crystals or as fibrous masses. It is colorless to white with occasional shades or tints of yellow and red. It has a Mohs hardness of 2.5 to 3 and a specific gravity of 5.76.Pradyot Patnaik. ''Handbook of Inorganic Chemicals''. McGraw-Hill, 2002, Valentinite occurs as a weathering product of stibnite and other antimony minerals. It is dimorphous with the isometric antimony oxide senarmontite. Historical data Valentinite is a mineral named in the middle of the 19th century in honour of Basilius Valentinus, a writer on alchemy. He is the supposed author of the first book to give a detailed description of antimony and its compounds. From the contents of the book it is also obvious that Valentinus was familiar with the synthetic preparation of antimony trioxide, which was called 'the antimony flower'. Valentinite w ...

Stibiconite
Stibiconite is an antimony oxide mineral with formula: Sb3O6(OH). Its name originates from Greek "stibi" (antimony) and "konis" (powder), alluding to its composition and habit. It is a member of the pyrochlore super group. Discovery and occurrence It was first described in 1862 for an occurrence in the Brandholz - Goldkronach District, Fichtelgebirge, Franconia, Bavaria. It occurs as a secondary alteration product of other hydrothermal antimony minerals such as stibnite. It occurs in association with cervantite, valentinite, kermesite Kermesite or antimony oxysulfide is also known as red antimony (Sb2S2O) . The mineral's color ranges from cherry red to a dark red to a black.

Triclinic
180px, Triclinic (a ≠ b ≠ c and α ≠ β ≠ γ ) In crystallography, the triclinic (or anorthic) crystal system is one of the 7 crystal systems. A crystal system is described by three basis vectors. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system. In addition, the angles between these vectors must all be different and may not include 90°. The triclinic lattice is the least symmetric of the 14 three-dimensional Bravais lattices. It has (itself) the minimum symmetry all lattices have: points of inversion at each lattice point and at 7 more points for each lattice point: at the midpoints of the edges and the faces, and at the center points. It is the only lattice type that itself has no mirror planes.

Broken Hill
Broken Hill is an inland mining city in the far west of outback New South Wales, Australia. It is near the border with South Australia on the crossing of the Barrier Highway (A32) and the Silver City Highway (B79), in the Barrier Range. It is 315m above sea level, with a hot desert climate, and an average rainfall of 235mm. The closest major city is Adelaide, the capital of South Australia, which is more than 500km to the southwest and linked via route A32. The town is prominent in Australia's mining, industrial relations and economic history after the discovery of silver ore led to the opening of various mines, thus establishing Broken Hill's recognition as a prosperous mining town well into the 1990s. Despite experiencing a slowing economic situation into the late 1990s and 2000s, Broken Hill itself was listed on the National Heritage List in 2015 and remains Australia's longest running mining town. Broken Hill, historically considered one of Australia's boomtowns, has be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Land Of Punt
The Land of Punt ( Egyptian: '' pwnt''; alternate Egyptological readings ''Pwene''(''t'') /pu:nt/) was an ancient kingdom known from Ancient Egyptian trade records. It produced and exported gold, aromatic resins, blackwood, ebony, ivory and wild animals.Shaw & Nicholson, p. 231. It is possible that it corresponds to Opone in Somalia, as later known by the ancient Greeks, while some biblical scholars have identified it with the biblical land of Put or Havilah. At times Punt is referred to as ''Ta netjer'' ('' tꜣ nṯr''), the "Land of the God". The exact location of Punt is debated by historians. Various locations have been offered, southeast of Egypt, a Red Sea coastal region: Somaliland, Somalia, Djibouti, northeast Ethiopia, Eritrea, and north-east Sudan. It is also possible that it covered both the Horn of Africa and Southern Arabia.Dimitri Meeks – Chapter 4 – "Locating Punt" from the book ''Mysterious Lands''", by David B. O'Connor and Stephen Quirke. Puntlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Hatshepsut
Hatshepsut (; also Hatchepsut; Egyptian: '' ḥꜣt- špswt'' "Foremost of Noble Ladies"; or Hatasu c. 1507–1458 BC) was the fifth pharaoh of the Eighteenth Dynasty of Egypt. She was the second historically confirmed female pharaoh, after Sobekneferu. (Various other women may have also ruled as pharaohs or at least regents before Hatshepsut, as early as Neithhotep around 1,600 years prior.) Hatshepsut came to the throne of Egypt in 1478 BC. As the principal wife of Thutmose II, Hatshepsut initially ruled as regent to Thutmose III, a son of Thutmose II by another wife and the first male heir. While Thutmose III had inherited the throne at about two years old, Hatshepsut continued to rule by asserting her lineage as the daughter and only child of Thutmose I and his primary wife, Ahmose. Her husband Thutmose II was the son of Thutmose I and a secondary wife named Mutnofret, who carried the title 'King's daughter' and was probably a child of Ahmose I. Hatshepsut and Thutmos ...

Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression traces back to 1615, when it first appeared in a book by Johannes Kepler as the la, annus aerae nostrae vulgaris (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the later 20th century, BCE and CE have become popular in academic and scientific publications because BCE and CE are religiously neutral terms. They are used by others who wish to be sensit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Kingdom
In ancient Egyptian history, the Old Kingdom is the period spanning c. 2700–2200 BC. It is also known as the "Age of the Pyramids" or the "Age of the Pyramid Builders", as it encompasses the reigns of the great pyramid-builders of the Fourth Dynasty, such as King Sneferu, who perfected the art of pyramid-building, and the kings Khufu, Khafre and Menkaure, who constructed the pyramids at Giza. Egypt attained its first sustained peak of civilization during the Old Kingdom, the first of three so-called "Kingdom" periods (followed by the Middle Kingdom and New Kingdom), which mark the high points of civilization in the lower Nile Valley. The concept of an "Old Kingdom" as one of three "golden ages" was coined in 1845 by the German Egyptologist Baron von Bunsen, and its definition would evolve significantly throughout the 19th and the 20th centuries. Not only was the last king of the Early Dynastic Period related to the first two kings of the Old Kingdom, but the "capital", ...

Kermes Mineral
Kermes mineral or ''Alkermes mineral'' was a compound of antimony oxides and sulfides, more specifically, antimony trioxide and trisulfide. It can be made or obtained in the laboratory by the actions of potassium carbonate (K2CO3) on antimony sulfide. The compound is reddish brown in color and described as a velvety powder which is insoluble in water. It was used extensively in the medical field until the general use of antimony compounds declined due to toxic effects. History and Uses The name is derived from the word ''kermes'' as denoting the compound’s red color. The origins of the term is from the French ''kermès'', which is short for ''alkermès'', from the Arabic ''al-qirmiz'' a reference to crimson dye made from the bodies of insects (see Kermes (dye)). It was also known as poudre des Chartreux from a story of how it saved the life of a Carthusian monk in 1714.{{cite EB1911 , wstitle=Kermes , volume=15 , page=746 Because of its reputation as a medication and h ...

Kermes (dye)
Kermes is a red dye derived from the dried bodies of the females of a scale insect in the genus '' Kermes'', primarily ''Kermes vermilio''. The ''Kermes'' insects are native in the Mediterranean region and are parasites living on the sap of the host plant, the Kermes oak (''Quercus coccifera'') and the Palestine oak (''Quercus calliprinos'').Amar, ''et al''. (2005), p. 1081 These insects were used as a red dye since antiquity by the ancient Egyptians, Mesopotamians, Indians, Greeks, Romans, and Iranians. The kermes dye is a rich red, a crimson. It has good colour fastness in silk and wool. It was much esteemed in the medieval era for dyeing silk and wool, particularly scarlet cloth. Post-medievally it was replaced by other red dyes, starting with cochineal. Etymology Kermes ultimately derives from the Sanskrit word कृमिज or ''kṛmija'' meaning "worm-made". This was adopted into Persian and later Arabic as قرمز ''qermez''. The modern English word kermes was borro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
