It differs significantly from the recipe for true or hard paste porcelain, which was first discovered by the Chinese about a 1000 years ago then rediscovered by Meissen about 1710.Hard paste porcelain is a mixture of kaolin and petunse, or china clay and china stone, mixed and then fired to a temperature of about 1350C degrees.The first Chinese blue and white wares were as early as the ninth century in Henan province, China; although only shards have been discovered.Tang period blue-and-white is even rarer than Song blue-and-white and was unknown before 1985.

Traditional East Asian thinking only classifies pottery into low-fired wares (earthenware) and high-fired wares (porcelain), without the intermediate European class of stoneware, and the many local types of stoneware were mostly classed as porcelain, though often not white and translucent.Blue and white decoration first became widely used in Chinese porcelain in the 14th century, after the cobalt pigment for the blue began to be imported from Persia.A style of decoration based on sinuous plant forms spreading across the object was perfected, and most commonly used.Porcelain was first developed in China around 2,000 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.
