Spindle Whorl
A spindle whorl is a disc or spherical object fitted onto the spindle to increase and maintain the speed of the spin. Historically, whorls have been made of materials like amber, antler, bone, ceramic, coral, glass, stone, metal (iron, lead, lead alloy), and wood (oak). Local sourced materials have been also used, such as chalk, limestone, mudstone, sandstone, slate, lydite and soapstone.

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ...

Viking Age
The Viking Age () was the period during the Middle Ages when Norsemen known as Vikings undertook large-scale raiding, colonizing, conquest, and trading throughout Europe and reached North America. It followed the Migration Period and the Germanic Iron Age. The Viking Age applies not only to their homeland of Scandinavia but also to any place significantly settled by Scandinavians during the period. The Scandinavians of the Viking Age are often referred to as ''Vikings'' as well as ''Norsemen'', although few of them were Vikings in sense of being engaged in piracy. Voyaging by sea from their homelands in Denmark, Norway, and Sweden, the Norse people settled in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, and the Baltic coast and along the Dnieper and Volga trade routes in eastern Europe, where they were also known as Varangians. They also briefly settled in Newfoundland, becoming the first Europeans to reach North America. The Norse-Gaels, ...

Muisca
The Muisca (also called Chibcha) are an indigenous people and culture of the Altiplano Cundiboyacense, Colombia, that formed the Muisca Confederation before the Spanish conquest. The people spoke Muysccubun, a language of the Chibchan language family, also called ''Muysca'' and ''Mosca''. They were encountered by conquistadors dispatched by the Spanish Empire in 1537 at the time of the conquest. Subgroupings of the Muisca were mostly identified by their allegiances to three great rulers: the ''hoa'', centered in Hunza, ruling a territory roughly covering modern southern and northeastern Boyacá and southern Santander; the '' psihipqua'', centered in Muyquytá and encompassing most of modern Cundinamarca, the western Llanos; and the '' iraca'', religious ruler of Suamox and modern northeastern Boyacá and southwestern Santander. The territory of the Muisca spanned an area of around from the north of Boyacá to the Sumapaz Páramo and from the summits to the western p ...

Kerameikos
Kerameikos (, ) also known by its Latinized form Ceramicus, is an area of Athens, Greece, located to the northwest of the Acropolis, which includes an extensive area both within and outside the ancient city walls, on both sides of the Dipylon Gate and by the banks of the Eridanos River. It was the potters' quarter of the city, from which the English word "ceramic" is derived, and was also the site of an important cemetery and numerous funerary sculptures erected along the Sacred Way, a road from Athens to Eleusis. History and description The area took its name from the city square or dēmos (δῆμος) of the Kerameis (Κεραμεῖς, potters), which in turn derived its name from the word κέραμος (''kéramos'', "pottery clay", from which the English word "ceramic" is derived).Hans Rupprecht Goette, ''Athens, Attica and the Megarid: An Archaeological Guide'', p. 59 The "Inner Kerameikos" was the former "potters' quarter" within the city and "Outer Kerameikos" cove ...

Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical G ...

Brooklyn Museum
The Brooklyn Museum is an art museum located in the New York City borough of Brooklyn. At , the museum is New York City's second largest and contains an art collection with around 1.5 million objects. Located near the Prospect Heights, Crown Heights, Flatbush, and Park Slope neighborhoods of Brooklyn, the museum's Beaux-Arts building was designed by McKim, Mead and White. The Brooklyn Museum was founded in 1898 as a division of the Brooklyn Institute of Arts and Sciences and was planned to be the largest art museum in the world. The museum initially struggled to maintain its building and collection, only to be revitalized in the late 20th century, thanks to major renovations. Significant areas of the collection include antiquities, specifically their collection of Egyptian antiquities spanning over 3,000 years. European, African, Oceanic, and Japanese art make for notable antiquities collections as well. American art is heavily represented, starting at the Colonial period. A ...

Soapstone
Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock. It is composed largely of the magnesium rich mineral talc. It is produced by dynamothermal metamorphism and metasomatism, which occur in the zones where tectonic plates are subducted, changing rocks by heat and pressure, with influx of fluids, but without melting. It has been a medium for carving for thousands of years. Terminology The definitions of the terms "steatite" and "soapstone" vary with the field of study. In geology, steatite is a rock that is to a very large extent composed of talc. The mining industry will define steatite as a high-purity talc rock that is suitable for manufacturing of, for example, insulators, the lesser grades of the mineral can be called simply "talc rock". Steatite can be used both in lumps ("block steatite", "lava steatite", "lava grade talc"), and in the ground form. While the geologists logically will use "steatite" to designate both forms, ...

Lydite
Radiolarite is a siliceous, comparatively hard, fine-grained, chert-like, and homogeneous sedimentary rock that is composed predominantly of the microscopic remains of radiolarians. This term is also used for indurated radiolarian oozes and sometimes as a synonym of radiolarian earth. However, radiolarian earth is typically regarded by Earth scientists to be the unconsolidated equivalent of a radiolarite. A radiolarian chert is well-bedded, microcrystalline radiolarite that has a well-developed siliceous cement or groundmass.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. Mineralogy and petrology Radiolarites are biogenic, marine, finely layered sedimentary rocks. The layers reveal an interchange of clastic mica grains, radiolarian tests, carbonates and organic pigments. Clay minerals are usually not abundant. Radiolarites deposited in relatively shallow dep ...

Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for ex ...

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ...
