Petuntse, also known as china stone, is a key ingredient in the production of porcelain. It is a type of feldspar that, when mixed with kaolin clay, helps to create a strong and translucent ceramic body. Petuntse provides the necessary fluxes and minerals that contribute to the unique properties of porcelain, such as its hardness, whiteness, and ability to withstand high temperatures during firing.

Is it possible for them to use pig bone ashes in making bone china?
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
