Pottery that is not vitrified and is porous unless glazed.
white, tan, or reddish pottery fired at a low temperature. Also any type of clay which has a low firing range.
One of the three main types of pottery, the others being stoneware and porcelain. It is opaque, relatively soft, and porous unless covered with an uncrazed glaze. The firing temperature can be as low as 800 ºC, as with some African pottery, or as high as 1200 ºC before it starts to vitrify, and technically becomes stoneware.
Clay-based ceramics fired at considerably lower kiln temperatures than porcelain. Essentially, earthenwares are porous and require glazing for most applications. Pottery is another term for earthenware, whereas porcelain is a different animal altogether.
Often referred to as "pottery". The clays used for earthenware usually have a relatively low upper limit for the temperature at which they can be successfully fired, and earthenwares are fired between 800°C-1100°C. Earthenware bodies appear in a wide range of colours, and after firing still have a porosity of more than 5%. They are permeable, but can be made impermeable by glazing. The most common glaze used on earthenwares in China is a lead-fluxed glaze.
A clay body, opaque when fired and porous before glazing.
A porous piece of pottery made from clay, lightly fired and still pervious to liquids. A glaze is needed to make it waterproof.
A type of clay fired at low temperatures. The result is not as strong as china.
is a heavy, slightly porous ceramic often used for everyday china. It was used to make most ancient and antique pottery, including English Delft. It's often glazed, and not as heavy as and less durable than stoneware.
Dishes post and the like made of a coarse grade of baked clay, porous clay.
Earthenware is the most porous of the three main types of ceramic ware, having a porosity of more than 5% after firing. Most of the clays used to make earthenware are only suitable for firing to a relatively low temperature, between 800-1100oC. After firing the ceramics are permeable, and vessels are therefore frequently glazed. The most common glazes used on Chinese earthenwares are lead-fluxed glazes. In China, earthenwares are designated tao to differentiate them from high-fired wares such as stoneware or porcelain.
A basic, inexpensive form of pottery.
Any opaque ware which is fired once for biscuit and a second time for glaze.
A low fired clay body. Glazed pottery is fired to a temperature of 1,830 - 2,010 degrees Fahrenheit. Available in red or also white.
Ceramics made of opaque, slightly porous clay that is fired at a relatively low heat.
A clay-based ceramic body which is not fully vitrified (q.v.), ie. the glaze and body remain separate layers, and is therefore relatively porous. Earthenware bodies can be quite variable in colour and texture: by definition, earthenware includes the fine white-bodied glazed tablewares of Wedgwood as well as the low-fired common pottery of much of the archaeological record. It is fired at temperatures between about 850ºC and 1100ºC, and not exceeding 1150ºC. It may be glazed or un-glazed.
ceramic ware made of porous clay fired at low heat
porous ceramic material fired to only about 800°C (1500°F); sometimes made impervious to liquids by the addition of a lead glaze, as in Hafner ware and folk pottery; see stoneware.
thick, opaque, porous-bodied dinnerware made from clays that cannot sustain as high a temperature as fine china. Earthenware is generally heavier, and its porous body cannot withstand temperature extremes such as going directly from the freezer to the oven. May be dishwasher safe if fully glazed.
Ceramics containing a low proportion of silica and fired at low temperatures (900 – 1150o F). Earthenwares are porous and must be sealed with a glaze to hold liquids.
a heavier, opaque ware, porous after the first firing, then decorated and glazed before a final firing. Most Shelley earthenware was produced between 1910 and 1940.
(or quarry) - A glazed or non-glazed non-vitreous ceramic, used for paving tiles. Usually coloured either cream or terracotta.
Generally refers to a low-fired clay. More specifically, it is a non-vitreous clay with an absorbency of from 5 to 20 percent.
Porous pottery that matures at a low firing temperature.
clay fired at a low kiln temperature around 800–1,100°C . Earthenware is not very strong and is porous.
Ceramic ware, usually coarse and reddish in color, fired in the lowest temperature ranges. Used for domestic ware, glazed or unglazed.
Is a clay product fired at the lowest temperature and is very delicate.
This type of clay needs to be glazed, it is porous and not waterproof. Earthenware is a low-fire clay.
Porous pottery body fired at below 1100°C
A low-fire porous clay bodies which are fired to maturity at approx. 2000°F. They are not waterproof and must be glazed to be used.
A low fired form of pottery (porous clay bodies) which are fired to maturity at approx. 1100°C.
Low-fired pottery (under 2000F), usually red or tan in color with an absorbency of 5 to 20 percent.
The basic mixture for earthenware is potash, sand, feldspar and clay. This type of dinnerware is fired at anywhere from 600 to 1,200 degrees Fahrenheit — usually around 900 degrees Fahrenheit. Earthenware (often mistakenly referred to as "china" is not made from a hard paste. It has a softer body and is much cheaper to produce. It can be made almost as thin as bone china, but it lacks translucency. It is not as durable as bone china and chips more easily. However, it is much less expensive, lends itself to colorful decorations and is often interesting and quite beautiful.
an opaque, porous and coarse ceramic ware that is fired at a relatively low temperature (700º–1200ºC). Raku Ware – a type of earthenware that originated in Kyoto, Japan, in the 16th century. Raku (meaning "pleasure") has a rough, handmade and unpredictable appearance. The technique involves heating bisqued work to a red-hot temperature, removing it from the kiln and allowing it to burn in wood shavings, newspaper or a similar combustible material. Slipware – a decorative technique using slip, a liquid mixture of fine clay and water. The slip can be coloured with oxides or coloured clays and applied to the vessel by dipping or painting, or trailed on like icing on a cake. Terra Cotta – a lightly fired, unglazed earthenware usually reddish in colour. It has frequently been used by sculptors and modellers to produce models or studies for more finished pieces in other materials.
Pottery made from a porous clay that is fired at relatively low temperatures.
A type of claybody usually associated with low-fired ceramics. Earthenware tends to be more porous than higher fired clays. The relatively low physical hardness of both the clay and the glaze tend to make earthenware less durable then higher fired claybodies and less appropriate a choice for functional pieces. See also stoneware, porcelain.
A moderately porous pottery body which is fired to a temperature somewhat below that required to produce a vitreous article.
A type of clayware fired at comparatively low temperatures producing a heavy porous body that is opaque, not as strong as china, and lacking that product's resonance. Because earthenware dinnerware is generally in the low and medium price brackets and lends itself to a variety of decorative styles and methods, it is well suited for everyday use.
Any type of ceramic that remains porous (not waterproof) when it has been fired (baked) in a kiln.
Pots that are porous when unglazed. Usually fired at low temperatures. Earthenware is softer and more easily damaged than stoneware.
Earthenware is a common ceramic material, which is used extensively for pottery tableware and decorative objects. Although body formulations vary tremendously between countries, and even between individual makers, a generic composition is 25% ball clay, 28% kaolin, 32% quartz, and 15% feldspar. Earthenware is one of the oldest materials used in pottery.
