Pit Fired Pottery
Pit firing is the oldest known method for the firing of pottery. Examples have been dated as early as 29,000–25,000 BCE, while the earliest known kiln dates to around 6000 BCE, and was found at the Yarim Tepe site in modern Iraq. Kilns allow higher temperatures to be reached, use fuel more efficiently, and have long replaced pit firing as the most widespread method of firing pottery, although the technique still finds limited use amongst certain studio potters and in Africa. Unfired pots are nestled together in a pit in the ground and are surrounded by combustible materials such as wood, shavings, dried manure, leaves, and sometimes metal oxides and salts to affect the surface of the pots. The top of the pit may be protected with moist clay, shards, larger pieces of wood, or metal baffles. The filled pit is then set on fire and carefully tended until most of the inner fuel has been consumed. At around the maximum temperatures are moderate compared to other techniqu ...

Pottery Firing Mali
Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural ''potteries''). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". End applications include tableware, ceramic art, decorative ware, toilet, sanitary ware, and in technology and industry such as Insulator (electricity), electrical insulators and laboratory ware. In art history and archaeology, especially of ancient and prehistoric periods, pottery often means only vessels, and sculpture, sculpted figurines of the same material are called terracottas. Pottery is one of the Timeline of historic inventions, oldest human inventions, originating before the Neolithic, Neolithic period, w ...

Salts
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions ( cations) and negatively charged ions (anions), which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds. The component ions in a salt can be either inorganic, such as chloride (Cl−), or organic, such as acetate (). Each ion can be either monatomic, such as sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic, such as ammonium () and carbonate () ions in ammonium carbonate. Salts containing basic ions hydroxide (OH−) or oxide (O2−) are classified as bases, such as sodium hydroxide and potassium oxide. Individual ions within a salt usually have multiple near neighbours, so they are not considered to be part of molecules, but instead part of a continuous three-dimensional network. Salts usually form crystalline structures when solid. Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pueblo Pottery
Pueblo pottery are ceramic objects made by the Indigenous Puebloans, Pueblo people and their antecedents, the Ancestral Puebloans and Mogollon cultures in the Southwestern United States and Northern Mexico. For centuries, pottery has been central to pueblo life as a feature of ceremonial and utilitarian usage. The clay is locally sourced, most frequently handmade (not thrown on a potters wheel nor cast in a mold), and fired traditionally in an Pit fired pottery, earthen pit. These items take the form of storage jars, canteens, serving bowls, seed jars, and ladles. Some utility wares were undecorated except from simple corrugations or marks made with a stick or fingernail, however many examples for centuries were painted with abstract or representational motifs. Some pueblos made Effigy, effigy vessels, Zuni fetishes, fetishes or figurines. During modern times, pueblo pottery was produced specifically as an art form to serve an economic function. This role is not dissimilar to pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthenware
Earthenware is glazed or unglazed Vitrification#Ceramics, nonvitreous pottery that has normally been fired below . Basic earthenware, often called terracotta, absorbs liquids such as water. However, earthenware can be made impervious to liquids by coating it with a ceramic glaze, and such a process is used for the great majority of modern domestic earthenware. The main other important types of pottery are porcelain, bone china, and stoneware, all fired at high enough temperatures to vitrify. End applications include tableware and ceramic art, decorative ware such as figurines. Earthenware comprises "most building bricks, nearly all European pottery up to the seventeenth century, most of the wares of Egypt, Persia and the near East; Greek, Roman and Mediterranean, and some of the Chinese; and the fine earthenware which forms the greater part of our tableware today" ("today" being 1962).Dora Billington, ''The Technique of Pottery'', London: B.T.Batsford, 1962 Pit fired pottery, P ...

Oxides
An oxide () is a chemical compound containing at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of −2) of oxygen, an O2− ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of (called a passivation layer) that protects the foil from further oxidation.Greenwood, N. N.; & Earnshaw, A. (1997). Chemistry of the Elements (2nd Edn.), Oxford:Butterworth-Heinemann. . Stoichiometry Oxides are extraordinarily diverse in terms of stoichiometries (the measurable relationship between reactants and chemical equations of an equation or reaction) and in terms of the structures of each stoichiometry. Most elements form oxides of more than one stoichiometry. A well known example is carbon monoxide and carbon dioxide.Greenwood, N. N.; & Earnshaw, A. (1 ...

Manure
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi, and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web. Types There are in the 21st century three main classes of manures used in soil management: Animal manure Most animal manure consists of feces. Common forms of animal manure include farmyard manure (or farm slurry ( liquid manure). Farmyard manure also contains plant material (often straw), which has been used as bedding for animals and has absorbed the feces and urine. Agricultural manure in liquid form, known as slurry, is produced by more intensive livestock rearing systems where concrete or slats are used instead of straw bedding. M ...
