A species of coarse potter's ware, glazed and baked.
A utilitarian vessel that has a hard, but grainy, and generally less refined paste than earthenware. Often salt glazed or coated with a brown or buff slip, but should be vitrified enough to be waterproof without additional surface treatments.
natural clay, or blend of clays which is fired over 2100 degrees F. It differs from porcelain principally in color, being gray, tan or reddish, and having a larger "grain."
Stoneware is a strong opaque ceramic ware that is high-fired, well vitrified, and nonporous.
White clay with fine ground stone. Working with stoneware demands great expertise, and is in fact becoming a lost art. Stoneware is safe to use in microwave and conventional ovens.
Highly vitrified ceramics fired to above 1200oC, 2192 oF. Most of the silica in a fired stoneware body is melted into a glassy matrix and the resulting body is of high density and usually has a water absorption rate of less than 1%.
A vitreous high-fired pottery. The body can be found in white, gray, brown, red, and buff. Some 18th century stonewares exhibit exceedingly thin, lightweight bodies, while others are thick and rugged.
An impermeable ceramic, which is harder and stronger than earthenware. Stonewares are usually fired at between 1200° and 1300°C. The body material is of various colours and when fired stonewares are not translucent. In China the body and glaze of stonewares are usually fired at the same temperature and form an integrated body-glaze layer.
Pottery made of clay and a fusible stone; fired between 1200°C and 1400°C, halfway between earthenware and porcelain; opaque, very hard and nonporous; additional glaze is unnecessary except for decoration.
A hard, light-colored clay that is not porous, but the resulting ware is sturdier than earthenware.
Subsoil] Passage leading westwards from the north end of Earthenware (just south of Hardware)
Natural clay, or blend of clays, which is fired over 2100° Fahrenheit for little or no absorbency. Its main difference from porcelain is principally in color â€” being gray, tan or reddish.
Stoneware is harder and stronger than earthenware. The material sinters and fuses during firing to form an impermeable body. In China stoneware is fired at temperatures between 1200 and 1300oC. Unlike porcelain, stoneware appears in a variety of colors and is not translucent. The body and glaze of most Chinese stonewares are fired at the same time and form an integrated body/glaze layer that increases their strength. Chinese scholars rarely differentiate between stoneware and porcelain, using the same term ci (high-fired ceramic) for both.
Ceramics made of strong, opaque, nonporous clay that is fired at a high temperature.
ceramic ware that is fired in high heat and vitrified and nonporous
Non-porous ceramic paste in which there is enough silica content that when fired at a high temperature (ca. 1200o C), partial vitrification occurs.
china which is somewhere between porcelain and earthenware but much stronger than either. It is opaque, intensely hard, and non-porous.
A hard, dense, non-porous pottery made from clay and feldspar, which although not translucent or white in appearance, is often compared with porcelain.
is a type of clay used for ceramics that usually is a beige to white color and is fired at a high temperature. It also refers to one of the colors of the resin castings in our limited editions because they are the same light beige color.
High-firing clay with little or no rate of absorbency. Closer to porcelain than earthenware, it is more plastic and depends upon its impurities for its color and texture.
a hard clayware made of light-colored clay and dired at high temperatures. It is non-porous and quite durable but does not have the translucence of fine chine.
Is a clay that is fired at a much higher temperature than earthenware, resulting in a harder and more durable product.
Sturdier then earthenware, stoneware is waterproof even without being glazed.
High temperature pottery body. Fires at up to 1280°C, when vitrification occurs.
A combination of clays which form a stone-like vitreous body during firing.
a vitrified ceramic material, usually a silicate clay, that is very hard, rather heavy, and impervious to liquids and most stains; achieved at firing temperatures between 1200°C (2200°F) and 1300°C (2350°F); early stoneware, or Frühsteinzeug, did not quite reach those temperatures or was made from clays needing higher temperatures to vitrify, and was common from the 1300s to the early 1500s; color is usually gray or tan, but terra cotta and other colors were also made; see earthenware, pottery and porcelain.
A high-fired ware (above cone 8) with a slight or no absorbency. It is usually gray in color but may be tan or slightly reddish. Stoneware is similar in many respects to porcelain, the chief difference being the color which is the result of iron and other impurities in the clay.
A high fired ceramic body which is vitreous, not translucent and usually made of native clays.
a dense, fine-grained, non-translucent, vitrified clay body that is impervious to liquids and fired at a high temperature (1200Âºâ€“1350ÂºC). The clay contains significant amounts of aluminum silicates.
Pottery which is fired at a higher temperature than earthenware. Generally very durable and porous.
heavy nonporous pottery
A particular type of clay which vitrifies completely at moderately high firing temperatures. Stoneware is durable enough for practical objects like crockery, or tiles for walls or for countertops that get moderate use. When fully vitrified (high-fired), stoneware tiles can usually be used on floors that get moderate traffic, but not heavy or commerical-levels of use. To date, most of my work is stoneware. I sometimes fire my stoneware clay at a temperature lower than the maximum the clay can withstand. This is usually to control the final color of the clay or glazes, and means the piece may be less durable than a high-fired item made from the same clay. But don't expect it to crumble in your hands -- it'll hold up to the kinds of uses I describe for each item. (Ask, if I don't cover your particular idea.)
A form of dinnerware that is more durable and heat resistant than Earthenware, since it is fired at higher kiln temperatures.
A strong, hard, vitrified ware, usually high-fired above 2,200 F, in which the claybody and glaze mature at the same temperature, forming an integrated clay-glaze layer. This high-firing process brings the clay to a point of maximum solidification without danger of distortion, creating pieces very suitable for kitchenware and other functional pieces. See also earthenware, porcelain, claybody.
An opaque ceramic containing a naturally vitrifying clay e.g., a stoneware clay or a suitable ball clay. Sometimes a non-plastic constituent and a flux are added. See clay chart for vitrification temperatures.
A hard ware made of a single light clay and fired at a high temperature. It is non-porous and very durable but does not have the translucence of china.
Pottery fired at high temperature which is inherently non-porous. The clay vitrifies during firing and the surface will not absorb moisture. Stoneware can be left unglazed and still be usable for holding water, but it is more usual to glaze the inside of the vessel, at least. Stoneware is more durable than earthenware, and capable of resolving finer detail.
A gray-, reddish- or buff-colored opaque clay body which matures (becomes nonporous) between 1900 to 2300ºF.
Stoneware is a category of clay and a type of ceramic distinguished primarily by its firing and maturation temperature (from about 1200Â°C to 1315 Â°C). In essence, it is man-made stone. One widely recognized definition is from the Combined Nomenclature of the European Communities which 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.
