Porcelain is an ancient ceramic material perfected by the Chinese. There are examples of porcelain that date back to the 7th century. Porcelain is commonly called china, as this is where the material originated. There are three types of porcelain, hard paste, soft paste and bone china. In 1800, Josiah Spode II created bone china by adding bone ash to the formula for porcelain. The result was the hardest, most durable porcelain available. Hard paste porcelain is made from kaolin and petuntse. The materials are fired at high temperatures, with or without a glaze, and produce a hard, translucent material. Soft paste porcelain contains the kaolin and petuntse of hard paste but also includes frit - a combination of various materials like white sand, nitre, alum, salt and gypsum. The frit in the mixture liquefies and turns to glass when fired and the glassy bits fuse to the porcelain. The resulting soft paste porcelain has a grittier feel to it and is not as strong as hard paste porcelain. Bone china is the toughest of porcelains and does indeed contain bones. Bone ash makes up the greatest part of the formula for bone china, with the balance of the formula containing kaolin and petuntse. The resulting material is hard, resilient and an ivory white in color. It remains the standard for porcelain manufactured in England. Bone ash comes from the pulverized and burned bones of animals. All tissue is removed from the bones and they are fired at temperatures of up to 1000 degrees. The resulting ash is crushed to a powder and mixed with water before being added to the other porcelain material. http://www.essortment.com/all/bonechinaporce_rmbs.htm

What is the difference between fine bone China and China?
Several processes are involved in the making of bone china, but the ingredient that sets it apart from fine china, is the component of bone ash that is included in its manufacture. Hence where the name bone china comes from, and without this ash component, china is not really 'bone' china. It is also usually more expensive than other china, and this is justified by the processes and labour involved in its making. A piece of bone china contains at least 25% of bone ash, and this compound not only adds strength and white color to the china, but also makes it translucent. Not totally transparent, but enough for the light to pass through it.
