Ceramic art uses ceramic
Earthenware is pottery that has not been fired to vitrification and is thus permeable to water. Many types of pottery have been made from it from the earliest times, and until the 18th century it was the most common type of pottery outside the far East. Earthenware is often made from clay, quartz and feldspar. Terracotta, a type of earthenware, is a clay-based unglazed or glazed ceramic, where the fired body is porous.  Its uses include vessels (notably flower pots), water and waste water pipes, bricks, and surface embellishment in building construction.  Terracotta has been a common medium for ceramic art (see below).
Stoneware is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay.  Stoneware is fired at high temperatures. Vitrified or not, it is nonporous; it may or may not be glazed.  One widely recognised definition is from the Combined Nomenclature of the European Communities, a European industry standard states "Stoneware, which, though dense, impermeable and hard enough to resist scratching by a steel point, differs from porcelain because it is more opaque, and normally only partially vitrified. It may be vitreous or semi-vitreous. It is usually coloured grey or brownish because of impurities in the clay used for its manufacture, and is normally glazed."
Porcelain is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. Properties associated with porcelain include low permeability and elasticity; considerable strength, hardness, toughness, whiteness, translucency and resonance; and a high resistance to chemical attack and thermal shock.  Porcelain has been described as being "completely vitrified, hard, impermeable (even before glazing), white or artificially coloured, translucent (except when of considerable thickness), and resonant". However, the term porcelain lacks a universal definition and has "been applied in a very unsystematic fashion to substances of diverse kinds which have only certain surface-qualities in common".
Bone china (fine china) is a type of soft-paste porcelain 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.  Developed by English potter Josiah Spode, bone china is known for its high levels of whiteness and translucency, and very high mechanical strength and chip resistance. 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.  From its initial development and up to the later part of the twentieth century, bone china was almost exclusively an English product, with production being effectively localised in Stoke-on-Trent. Most major English firms made or still make it, including Mintons, Coalport, Spode, Royal Crown Derby, Royal Doulton, Wedgwood and Worcester.  In the UK, references to "china" or "porcelain" can refer to bone china, and "English porcelain" has been used as a term for it, both in the UK and around the world.  Fine china is not necessarily bone china, and is a term used to refer to ware which does not contain bone ash.Forms
Studio pottery
Studio pottery is pottery made by amateur or professional artists or artisans working alone or in small groups, making unique items or short runs. Typically, all stages of manufacture are carried out by the artists themselves.  Studio pottery includes functional wares such as tableware, cookware and non-functional wares such as sculpture.  Studio potters can be referred to as ceramic artists, ceramists, ceramicists or as an artist who uses clay as a medium. Much studio pottery is tableware or cookware but an increasing number of studio potters produce non-functional or sculptural items.  Some studio potters now prefer to call themselves ceramic artists, ceramists or simply artists. Studio pottery is represented by potters all over the world.Tile
A tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, or even glass, generally used for covering roofs, floors, walls, showers, or other objects such as tabletops. Alternatively, tile can sometimes refer to similar units made from lightweight materials such as perlite, wood, and mineral wool, typically used for wall and ceiling applications. In another sense, a "tile" is a construction tile or similar object, such as rectangular counters used in playing games (see tile-based game). The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, meaning a roof tile composed of fired clay.
Tiles are often used to form wall murals and floor coverings, and can range from simple square tiles to complex mosaics.  Tiles are most often made of ceramic, typically glazed for internal uses and unglazed for roofing, but other materials are also commonly used, such as glass, cork, concrete and other composite materials, and stone. Tiling stone is typically marble, onyx, granite or slate. Thinner tiles can be used on walls than on floors, which require more durable surfaces that will resist impacts.Tableware
Tableware is the dishes or dishware used for setting a table, serving food and dining. It includes cutlery, glassware, serving dishes and other useful items for practical as well as decorative purposes. Dishes, bowls and cups may be made of ceramic, while cutlery is typically made from metal, and glassware is often made from glass or other non-ceramic materials.  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. Special occasions are usually reflected in higher quality tableware.Cambodia
Recent archaeological excavations at Angkor Borei (in southern Cambodia) have recovered a large number of ceramics, some of which probably date back to the prehistoric period. Most of the pottery, however, dates to the pre-Angkorian period and consists mainly of pinkish terracotta pots which were either hand-made or thrown on a wheel, and then decorated with incised patterns.
Glazed wares first appear in the archaeological record at the end of the 9th century at the Roluos temple group in the Angkor region, where green-glazed pot shards have been found. A brown glaze became popular at the beginning of the 11th century and brown-glazed wares have been found in abundance at Khmer sites in northeast Thailand. Decorating pottery with animal forms was a popular style from the 11th to 13th century. Archaeological excavations in the Angkor region have revealed that towards the end of Angkor period production of indigenous pottery declined while there was a dramatic increase in Chinese ceramic imports.
Direct evidence of the shapes of vessels is provided by scenes depicted on bas-reliefs at Khmer temples, which also offer insight into domestic and ritualistic uses of the wares. The wide range of utilitarian shapes suggest the Khmers used ceramics in their daily life for cooking, food preservation, carrying and storing liquids, as containers for medicinal herbs, perfumes and cosmetics.
