Ceramic forming techniquesCeramic forming techniques are ways of forming ceramics, which are used to make everything from tableware such as teapots to engineering ceramics such as computer parts. Pottery techniques include the potter's wheel, slip casting and many others. Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of technology.
Slip (ceramics)A slip is a clay slurry used to produce pottery and other ceramic wares. Liquified clay, in which there is no fixed ratio of water and clay, is called slip or clay slurry which is used either for joining leather-hard (semi-hardened) clay body (pieces of pottery) together by slipcasting with mould, glazing or decorating the pottery by painting or dipping the pottery with slip. Pottery on which slip has been applied either for glazing or decoration is called slipware.
Bone chinaBone china is a type of vitreous, translucent pottery, the raw materials for which include bone ash, feldspathic material and kaolin. It has been defined as "ware with a translucent body" containing a minimum of 30% of phosphate derived from calcined animal bone or calcium phosphate. Bone china is amongst the strongest of whiteware ceramics, and is known for its high levels of whiteness and translucency.
PlasterPlaster is a building material typically used for cladding on interior walls, pool interiors, ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to a physically different mixture commonly used for exterior building wall cladding.

CorbridgeCorbridge is a village and civil parish in Northumberland, England, 16 miles (26 km) west of Newcastle and 4 miles (6 km) east of Hexham. In 2011 the parish had a population of 3672. Villages nearby include Halton, Acomb, Aydon and Sandhoe. EtymologyCorbridge was known to the Romans as something like Corstopitum or Coriosopitum, and wooden writing tablets found at the Roman fort of Vindolanda nearby suggest it was probably locally called Coria (meaning a tribal centre).
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.
TablewareTableware items are the dishware and utensils used for setting a table, serving food, and dining. The term includes cutlery, glassware, serving dishes, serving utensils, and other items used for practical as well as decorative purposes. The quality, nature, variety and number of objects varies according to culture, religion, number of diners, cuisine and occasion.
EarthenwareEarthenware is glazed or unglazed nonvitreous pottery that has normally been fired below 1,200 °C (2,190 °F). 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.
TeapotA teapot is a vessel used for steepingtea leaves or a herbal mix in boiling or near-boiling water and serving the resulting infusion called tea; usually put in a teacup. It is one of the core components of teaware. Teapots usually have an opening with a lid at their top, where the dry tea and hot water are added, a handle for holding by hand, and a spout through which the tea is served. Some teapots have a strainer built-in on the inner edge of the spout.
ThixotropyThixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed, or otherwise stressed (time-dependent viscosity). They then take a fixed time to return to a more viscous state.
BlungerA blunger is a machine commonly used in the pottery industry for mixing slip, a mixture of clay and water. A blunger usually consists of a round or octagonal tank with a mixer. Clay is added to the water-filled blunger and then mixed into a slurry, which is also called slip. The electrical charge of the clay particles is neutralized by the addition of a deflocculant, which assists in keeping the particles in suspension.
