Metate
A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas). Similar artifacts have been found in other regions, such as the sil-batta in Bihar and Jharkhand, India as well as other grinding stones in China. Design and use While varying in specific morphology, metates are typically made of a large stone with a smooth depression or bowl worn into the upper surface. Materials are ground on the metate using a smooth hand-held stone known as a '' mano'' or ''metlapil''. This action consists of a horizontal grinding motion that differs from the vertical crushing motion used in a mortar and pestle. The depth of the bowl varies, though they are typically not deeper than those of a mortar; deeper metate bowls indicate either a longer period o ...

Mano (stone)
A mano ( Spanish for ''hand'') is a ground stone tool used with a metate to process or grind food by hand. It is also known as metlapil, a term derived from Nahuatl. History Manos were used in prehistoric times to process wild seeds, nuts, and other food, generally used with greater frequency in the Archaic period, when people became more reliant upon local wild plant food for their diet. Later, Manos and metates were used to process cultivated maize.Gibbon, Guy E.; Ames, Kenneth M. (1998''Archaeology of Prehistoric Native America: An Encyclopedia''.pp. 107, 166. . In its early use in the American Southwest, the mano and metate were used to grind wild plants. The mano began as a one-handed tool. Once the maize cultivation became more prevalent, the mano became a larger, two-handed tool that more efficiently ground food against an evolved basin or trough metate. Besides food, Manos and metates were used to separate and pulverize clay from earthen debris and stones. The r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batan (stone)
The batán is a kitchen utensil used to process different kinds of foods in South American, Andean and Indian cuisine. It has a flat stone (the ''batán'' proper) and a grinding stone called an ''uña''. The uña is held in both hands and rocked over the food in the batán. Depending on the use, the uña's weight can be slightly held back, allowed to move freely, or used to apply additional pressure. The rocking movements also vary depending on the application, and the grinding is done dry or with water or oil. South America The batán has been used since before the arrival of Spaniards in South America. In Andean households many different dishes are prepared in this manner, in rural and urban areas. The most important use it has is for preparing llajwa. For many Bolivians, Peruvians, Ecuadoreans and Colombians it is not the same when done in a blender. It is also used to husk grains, wash quinoa from its alkaloid (saponin), grind grains, crush papalisa and even to prepare smal ...

Quern-stone
A quern-stone is a stone tool for hand-grinding a wide variety of materials, especially for various types of grains. They are used in pairs. The lower stationary stone of early examples is called a ''saddle quern'', while the upper mobile stone is called a ''muller'', ''rubber'', or ''handstone''. The upper stone was moved in a back-and-forth motion across the saddle quern. Later querns are known as ''rotary querns''. The central hole of a rotary quern is called the ''eye'', and a dish in the upper surface is known as the ''hopper''. A ''handle slot'' contained a handle which enabled the rotary quern to be rotated. They were first used in the Neolithic era to grind cereals into flour. Design The upper stones were usually concave while the lower ones were convex. Quern-stones are frequently identifiable by their grooved working surfaces which enabled the movement of flour. Sometimes a millrind was present as a piece of wood (or other material), which allowed the cereal et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar And Pestle
A mortar and pestle is a set of two simple tools used to prepare ingredients or substances by compression (physics), crushing and shear force, grinding them into a fine Paste (rheology), paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hardwood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, or rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since the Stone Age; today they are typically associated with the pharmacy profession due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making Grog (clay), grog; ...

Volcanic Rock
Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "pyroclastics," and these are also technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-Columbian
In the history of the Americas, the pre-Columbian era, also known as the pre-contact era, or as the pre-Cabraline era specifically in Brazil, spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European colonization of the Americas, European colonization, which began with Christopher Columbus's voyage in 1492. This era encompasses the history of Indigenous peoples of the Americas, Indigenous cultures prior to significant European influence, which in some cases did not occur until decades or even centuries after Columbus's arrival. During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major Earthworks (archaeology), earthworks, and Complex society, complex societal hierarchies. Some of these civilizations had declined by the time of the establishment of the first permanent European colonies, around the late 16th to early 17th centuries, and are know ...

Artifact (archaeology)
An artifact or artefact (British English) is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance; it is defined as an object recovered by archaeological endeavor, including cultural artifacts (of archaeological culture, cultural interest). "Artifact" is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with Biofact (archaeology), ecofacts and Feature (archaeology), features; all three of these can sometimes be found together at archaeological sites. They can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rectangular
In Euclidean plane geometry, a rectangle is a rectilinear convex polygon or a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a ''square''. The term "oblong" is used to refer to a non-square rectangle. A rectangle with vertices ''ABCD'' would be denoted as . The word rectangle comes from the Latin ''rectangulus'', which is a combination of ''rectus'' (as an adjective, right, proper) and ''angulus'' (angle). A crossed rectangle is a crossed (self-intersecting) quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals (therefore only two sides are parallel). It is a special case of an antiparallelogram, and its angles are not right angles and not all equal, though opposite angles are equal. Other geometries, such as spherical, e ...

Indigenous Peoples Of The North American Southwest
The Indigenous peoples of the North American Southwest are those in the current states of Colorado, Arizona, New Mexico, Utah, and Nevada in the western United States, and the states of Sonora and Chihuahua in northern Mexico. An often quoted statement from Erik Reed (1666) defined the Greater Southwest culture area as extending north to south from Durango, Mexico to Durango, Colorado and east to west from Las Vegas, Nevada to Las Vegas, New Mexico.Cordell, Linda S. and Maxine E. McBrinn 2012 ''Archaeology of the Southwest'', 3rd edition. Left Coast Press, Walnut Creek Other names sometimes used to define the region include "American Southwest", "Northern Mexico", "Chichimeca", and " Oasisamerica/ Aridoamerica". This region has long been occupied by hunter-gatherers and agricultural people. Many contemporary cultural traditions exist within the Greater Southwest, including Yuman-speaking peoples inhabiting the Colorado River valley, the uplands, and Baja California, O'odham p ...

Circle
A circle is a shape consisting of all point (geometry), points in a plane (mathematics), plane that are at a given distance from a given point, the Centre (geometry), centre. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter. A circle bounds a region of the plane called a Disk (mathematics), disc. The circle has been known since before the beginning of recorded history. Natural circles are common, such as the full moon or a slice of round fruit. The circle is the basis for the wheel, which, with related inventions such as gears, makes much of modern machinery possible. In mathematics, the study of the circle has helped inspire the development of geometry, astronomy and calculus.
