It combines well with both glazes and paint, and can be modelled very well, allowing a huge range of decorative treatments in tablewares, vessels and figurines. The European name, porcelain in English, come from the old Italian porcellana (cowrie shell) because of its resemblance to the translucent surface of the shell.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 wares bearing a red painted ‘COALBROOKDALE’ mark in upper case are extremely rare and highly collectible. Most are found on colourful floral encrusted porcelain wares. From June 1820 to c1830, a series of prominent printed ‘Society of Arts’ marks were placed on Coalport porcelain wares.c1810 to 1825, rare examples of Coalport porcelain is marked in underglaze blue, ‘Coalbrookdale’, ‘CD’ or ‘C. c1815 to 1825, some Coalport plates and dishes include impressed numerals. c1845 to 1855, Coalport produced many Sevres & Chelsea porcelain imitations that can often include copies of the original Sevres or Chelsea marks.

Seemingly Coalport was named Coalport because of the coal that was transferred from canal boats to river vessels in the Coalbrook Dale area. Very early Coalport porcelain was unmarked, (c1805 and before) and in reality marks were rarely used before 1820.Pottery of the Later Silla period (668–935) was initially simple in color, shape, and design. Buddhism, the dominant religion of the time in Korea, increased the demand for celadon-glazed wares (cheongja), causing cheongja celadon to evolve very quickly, with more organic shapes and decorations, such as animal and bird motifs.When making cheongja wares, a small amount of iron powder was added to the refined clay, which was then coated with a glaze and an additional small amount of iron powder, and then finally fired.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.

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 (depending on the definition used) at some point about 2,000 and 1,200 years ago, then slowly spread to other East Asian countries, and finally Europe and the rest of the world.
