Pottery is also: (1) the art and wares made by potters; (2) a ceramic material (3) a place where pottery wares are made; and (4) the business of the potter. (W) Published definitions of Pottery include: -- "All fired ceramic wares that contain clay when formed, except technical, structural, and refractory products."
In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. [1][2] For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur ...
Grog, temper for clay. Grog, also known as firesand and chamotte, is a raw material usually made from crushed and ground potsherds, reintroduced into crude clay to temper it before making ceramic ware. It has a high percentage of silica and alumina. It is normally available as a powder or chippings, and is an important ingredient in Coade stone.
The term "plastic arts" has been used historically to denote visual art forms (painting, sculpture, and ceramics) as opposed to literature or music. The related terms plasticity and plasticism became more widely used in the early 20th century by critics discussing modern painting, particularly the works of Paul Cézanne. [3]
Porcelain (/ ˈpɔːrs (ə) lɪn /) is a ceramic material made by heating raw materials, generally including kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from vitrification and the formation of the ...
Vitrification is the progressive partial fusion of a clay, or of a body, as a result of a firing process. As vitrification proceeds, the proportion of glassy bond increases and the apparent porosity of the fired product becomes progressively lower. [3][10] Vitreous bodies have open porosity, and may be either opaque or translucent.
Electroplasticity was first discovered by Eugene S. Machlin, who reported in 1959 that applying an electric field made NaCl weaker and more ductile. [2] Since then, the effect of electric fields on plasticity has been studied in many materials systems including metal, ceramics, and semiconductors.
In pottery, leather-hard is the condition of a clay or clay body when it has been partially dried to a consistency similar to leather of the same thickness as the clay. At this stage, the clay object has approximately 15% moisture content. The clay is still visibly damp (normally a darkish grey, if it began whiteish) but has dried enough to be ...
