Paper clay Paper clay (sometimes referred to as fiberclay) is any clay body to which processed cellulose fiber (paper being the most common) has been added. Earthenware, terra cotta, stoneware, porcelain and bone china clay bodies can be made into paper clay.t is widely used by potters to repair cracks in dry, conventional clay, as well as dry paper clay. Thinner and taller work can be built with partially dry or completely dry paper clay. Re-wetting paper clay is faster with paper clay than pure clay, as the paper fibres pull water more quickly into the clay body.

Clay minerals Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces.Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.They have been useful to humans since ancient times in agriculture and manufacturing.lay minerals are usually (but not necessarily) ultrafine-grained (normally considered to be less than 2 micrometres in size on standard particle size classifications) and so may require special analytical techniques for their identification and study.

Porcelain 1 The three main types of porcelain are true, or hard-paste, porcelain; artificial, or soft-paste, porcelain; and bone china. Porcelain was first made in China—in a primitive form during the Tang dynasty (618–907) and in the form best known in the West during the Yuan dynasty (1279–1368).

Clay and Pottery Kinds of Clay. The three most common types of clay are earthenware, stoneware, and kaolin. Earthenware, or common clay, contains many minerals, such as iron oxide (rust), and in its raw state may contain some sand or small bits of rock.Earthenware is a secondary clay that has been transported by moving water some distance, picking up minerals and other materials before settling in a river bed.ecause of its many impurities, earthenware melts at a cooler temperature than other clays. Called a low-fire clay, earthenware fires (or bakes) in a temperature range of 1700 to 2100°F (926–1150°C). After firing, it is still porous and—unless glazed—is often white or gray.

DIFFERENCES BETWEEN PORCELAIN, CHINA, AND BONE CHINA The composition of the porcelain clays is usually more malleable than the clays used for china ware. This allows for forming of more intricate and detailed shapes. China ware differs from porcelain not only in color shade, but also in the way it is fired. Where Porcelain becomes vitrified during the second firing (second firing is hotter than first firing), china ware is vitrified during a single firing. With the china, there is only a single firing.

- While the Chinese ceramic artisans stumbled on the discoveries of the well-known kaolin clay and glazing about 2000 years ago, the discovery of Zisha clay about 500 years ago is the third most important factor in Chinese ceramic history and is virtually unknown to the world today.onclusion: you should not expect to buy a utilitarian teapot made of true Zisha clay for less than a few hundred dollars regardless of how the pot looks or what the dealer tells you, less should you expect to buy a basic Zisha teapot made by Grandmaster for less than $10,000 from the local dealers today.

Fire clay Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick.ire clay is resistant to high temperatures, having fusion points higher than 1,600 °C (2,910 °F), therefore it is suitable for lining furnaces, as fire brick, and for manufacture of utensils used in the metalworking industries, such as crucibles, saggars, retorts and glassware.

Porcelain Porcelain /ˈpɔːrsəlɪn, ˈpɔːrslɪn/ is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C. 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. Porcelain slowly evolved in China and was finally achieved at some point about 2,000 and 1,200 years ago, then ...
