Sialk Pot (cropped)
Tepe Sialk ( fa, تپه سیلک) is a large ancient archeological site (a ''tepe'', "hill, tell") in a suburb of the city of Kashan, Isfahan Province, in central Iran, close to Fin Garden. The culture that inhabited this area has been linked to the Zayandeh River Culture. History A joint study between Iran's Cultural Heritage Organization, the Louvre, and the Institut Francais de Recherche en Iran also verifies the oldest settlements in Sialk to date to around 6000–5500 BC. The Sialk ziggurat was built around 3000 BC. Sialk, and the entire area around it, is thought to have originated as a result of the pristine large water sources nearby that still run today. The Cheshmeh ye Soleiman ("Solomon's Spring") has been bringing water to this area from nearby mountains for thousands of years. The Fin garden, built in its present form in the 17th century, is a popular tourist attraction. It is here that the kings of the Safavid dynasty would spend their vacations away from their c ...

Tania Ghirshman
Tania Ghirshman (1900–1984), born Antoinette Levienne, was a French archaeologist and Conservation-restoration of cultural heritage, restorationist of Ukrainian origin. Originally a dentist, Ghirshman became involved in archaeology after her marriage to Roman Ghirshman, with whom she directed numerous excavations in Iran and Afghanistan, most notably the ancient city of Susa. She abandoned her career as a dental surgeon and adapted her skills in dentistry to restoration accompanying her husband Roman Ghirshman on all of his missions providing much practical support especially during difficult circumstances. Drawing the illustration for his works she also helped in restorative works on the excavated projects, as well as providing reproductions for her husband's publications. Her memoir, ''Archéologue malgré moi'' (Archaeologist in Spite of Myself), was awarded a Prix Broquette-Gonin in literature by the Académie française in 1971. Her memoir gave a colourful description of her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Crucible
A crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. While crucibles were historically usually made from clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents. History Typology and chronology The form of the crucible has varied through time, with designs reflecting the process for which they are used, as well as regional variation. The earliest crucible forms derive from the sixth/fifth millennium B.C. in Eastern Europe and Iran. Chalcolithic Crucibles used for copper smelting were generally wide shallow vessels made from clay that lacks refractory properties which is similar to the types of clay used in other ceramics of the time. During the Chalcolithic period, crucibles were heated from the top by using blowpipes.Hauptmann A., 2003, ''Developments in copper Metallurgy During the Fourth and Third Millennia B.C. at Feinan'', Jorda ...

Litharge
Litharge (from Greek lithargyros, lithos (stone) + argyros (silver) ''λιθάργυρος'') is one of the natural mineral forms of lead(II) oxide, PbO. Litharge is a secondary mineral which forms from the oxidation of galena ores. It forms as coatings and encrustations with internal tetragonal crystal structure. It is dimorphous with the orthorhombic form massicot. It forms soft (Mohs hardness of 2), red, greasy-appearing crusts with a very high specific gravity of 9.14–9.35. PbO may be prepared by heating lead metal in air at approximately 600 °C (lead melts at only 300 °C). At this temperature it is also the end product of heating of other lead oxides in air. This is often done with a set of bellows pumping air over molten lead and causing the oxidized product to slip or fall off the top into a receptacle, where it quickly solidifies in minute scales. :PbO2 –(293 °C)→ Pb12O19 –(351 °C)→ Pb12O17 –(375 °C)→ Pb3O4 –(605 °C)→ PbO Historical term ...

Slag
Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by their precursor and processing conditions (e.g., Blast furnace (BF) slags, air-cooled blast furnace (ACBF) slag, basic oxygen furnace (BOF) slag, and electric arc furnace (EAF) slag) . Due to the large demand for these materials, slag production has also significantly increased throughout the years despite recycling (most notably in the iron and steelmaking industries) and upcycling efforts. The World Steel Association (WSA) estimates that 600 kg of by-products (~90 wt% is slags) are generated per tonne of steel produced. Composition Slag is usually a mixture of metal oxides and sili ...

Teppe Zagheh
Teppe Zagheh ( fa, تپه زاغه) is an early urban settlement located near Qazvin, Iran. In Persian, ''teppe'' means " tell, hill". Settlement The settlement has been dated to have been built in 6500 BCE. After the re-excavation of Zagheh in 2001, new radiocarbon dates were obtained. They indicate that the site was settled c. 5370–5070 BC and abandoned c. 4460–4240 BC. Thus, it may belong to only a single historical period, Transitional Chalcolithic. Yet there were also many small clay 'tokens', used as counting objects, that were found at Zagheh; these are variously-shaped, and are similar to such tokens at other Neolithic sites. These Zagheh tokens are dated typologically to 6500–5500 BC. Thus, there were probably two periods of occupation. ''Zagheh archaic painted ware'' (ca. 6000-5500 BC) was found in Tepe Sialk I, sub-levels 1-2. This is the early painted ware, that was first excavated at Teppe Zagheh.
