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. 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, decorative ware, sanitaryware, and in technology and industry such as electrical insulators and laboratory ware. In art history and archaeology, especially of ancient and prehistoric periods, pottery often means vessels only, and sculpted figurines of the same material are called terracottas.
Porcelain is a ceramic material made by heating raw materials, generally including kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C. The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. End applications include tableware, decorative ware such as figurines, and products in technology and industry such as electrical insulators and laboratory ware.
Earthenware 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. 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 decorative ware such as figurines.
Stoneware is a broad term for pottery fired at a relatively high temperature. A modern definition is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay. End applications include tableware, decorative ware such as vases.
Tableware 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. For example, Middle Eastern, Indian or Polynesian food culture and cuisine sometimes limits tableware to serving dishes, using bread or leaves as individual plates, and not infrequently without use of cutlery. Special occasions are usually reflected in higher quality tableware.
Bangladesh Export Import Company Limited, commonly known by its trade name BEXIMCO, is a Bangladeshi multinational conglomerate holding company, headquartered in Dhaka, Bangladesh. It was founded in the early 1970s.
Hard-paste porcelain, sometimes called "true porcelain", is a ceramic material that was originally made from a compound of the feldspathic rock petuntse and kaolin fired at a very high temperature, usually around 1400 °C. It was first made in China around the 7th or 8th century and has remained the most common type of Chinese porcelain.
Bone china is a type of ceramic that is composed of 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 animal bone and calculated calcium phosphate. Bone china is the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency. Its high strength allows it to be produced in thinner cross-sections than other types of porcelain. Like stoneware, it is vitrified, but is translucent due to differing mineral properties.
Slip casting, or slipcasting, is a ceramic forming technique, and is widely used by commercial industry as well as contemporary fine artists as a way of making various ceramic forms. This technique is suitable for simple functional objects such as cups and plates, as well as more complicated shapes like figurative ceramics that would be difficult to be reproduced by hand or other forming techniques. The technique involves a clay body slip which is essentially a liquid version of clay, usually prepared in a blunger, being poured into plaster moulds and allowed to form a layer, the cast, on the internal walls of the mould.
Royal Doulton is an English ceramic and home accessories manufacturer that was founded in 1815. Operating originally in Vauxhall, London, and later moving to Lambeth, in 1882 it opened a factory in Burslem, Stoke-on-Trent, in the centre of English pottery. From the start, the backbone of the business was a wide range of utilitarian wares, mostly stonewares, including storage jars, tankards and the like, and later extending to drain pipes, lavatories, water filters, electrical porcelain and other technical ceramics. From 1853 to 1901, its wares were marked Doulton & Co., then from 1901, when a royal warrant was given, Royal Doulton.
The room-temperature form of quartz, α-quartz, undergoes a reversible change in crystal structure at 573 °C to form β-quartz. This phenomenon is called an inversion, and for the α to β quartz inversion is accompanied by a linear expansion of 0.45%. This inversion can lead to cracking of ceramic ware if cooling occurs too quickly through the inversion temperature. This is called dunting, and the resultant faults as dunts. To avoid such thermal shock faults, cooling rates not exceeding 50 °C/hour have been recommended.

Chinese influences on Islamic pottery cover a period starting from at least the 8th century CE to the 19th century. This influence of Chinese ceramics has to be viewed in the broader context of the considerable importance of Chinese culture on Islamic arts in general.

Ironstone china, ironstone ware or most commonly just ironstone, is a type of vitreous pottery first made in the United Kingdom in the early 19th century. It is often classed as earthenware although in appearance and properties it is similar to fine stoneware. It was developed in the 19th century by potters in Staffordshire, England, as a cheaper, mass-produced alternative for porcelain.
Restaurant ware, or most commonly hotelware, is vitrified, ceramic tableware which exhibits high mechanical strength and is produced for use in hotels and restaurants. Tableware used in railway dining cars, passenger ships and airlines are also included in this category.
Shinepukur Ceramics is a ceramic manufacturing company based in Dhaka, Bangladesh.
A potbank is a colloquial name for a pottery factory in North Staffordshire used to make bone china, earthenware and sanitaryware.
Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware.
