The earliest European porcelains were produced at the Meissen factory in the early 18th century; they were formed from a paste composed of kaolin and alabaster and fired at temperatures up to 1,400 °C (2,552 °F) in a wood-fired kiln, producing a porcelain of great hardness, translucency, and strength.Later, the composition of the Meissen hard paste was changed and the alabaster was replaced by feldspar and quartz, allowing the pieces to be fired at lower temperatures.Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago, then slowly spread to other East Asian countries, and finally Europe and the rest of the world.Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it has usually been regarded as the most prestigious type of pottery for its delicacy, strength, and its white colour.These were technically superior, and continue to be produced.Soft-paste porcelains are fired at lower temperatures than hard-paste porcelain, therefore these wares are generally less hard than hard-paste porcelains.Other raw materials can include feldspar, ball clay, glass, bone ash, steatite, quartz, petuntse and alabaster.

They wet very quickly, meaning that small changes in the content of water can produce large changes in workability.Soapstone and lime were known to have been included in these compositions.These wares were not yet actual porcelain wares as they were not hard nor vitrified by firing kaolin clay at high temperatures.Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste and bone china.The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions.
