The quality of the finished product is based on how much bone is in the mixture; a high-quality bone china should contain at least 30 percent bone and can go as high as 40—45 percent.

Originating in China, the earliest porcelains used kaolin a type of clay and pegmatite a type of granite. Early European versions used clay and ground glass. In , German manufacturers started using feldspar instead of glass in a process that continues today. The raw materials are finely ground, cleaned, formed in a mold, and then fired. The firing process is what creates either porcelain or fine china. Fine china is much softer than porcelain, making it much more suitable for applications such as plates and cups. Bone china undergoes two firing processes. The second firing happens after the piece is glazed, and melts the glaze into the piece. Many pieces are hand painted or sprayed, though in some cases decals can also be applied. The addition of bone ash gives bone china a warm color, while fine china will be a brighter white. Porcelain is a much more durable material, and is much harder than either type of china. Bone china is a type of porcelain that is composed of bone ash , feldspathic material , and kaolin. In the midth century, English potters had not succeeded in making hard-paste porcelain as made in East Asia and but found bone ash a useful addition to their soft-paste porcelain mixtures, giving strength. This became standard at the Bow porcelain factory in London operating from around , and spread to some other English factories. The modern product was developed by the Staffordshire potter Josiah in the early s. Spode included kaolin , so his formula, sometimes called "Staffordshire bone-porcelain", was effectively hard-paste, but stronger, and versions were adopted by all the major English factories by around From its initial development and up to the latter part of the 20th century, bone china was almost exclusively an English product, with production being effectively localised in Stoke-on-Trent. In the UK, references to "china" or "porcelain" can refer to bone china, and "English porcelain" has been used as a term for it, both in the UK and around the world. The first development of what would become known as bone china was made by Thomas Frye at his Bow porcelain factory near Bow in East London in His factory was located very close to the cattle markets and slaughterhouses of London and Essex, and hence easy access to animal bones. Later, Josiah Spode in Stoke-on-Trent further developed the concept between and , introducing his "Stoke China" in He died suddenly the year later, and his son Josiah II quickly rechristened the ware "Bone china". Bone china quickly proved to be highly popular, leading to its production by other English manufacturers. The production of bone china is similar to porcelain, except that more care is needed because of its lower plasticity and a narrower vitrification range. For almost years from its development bone china was almost exclusively produced in the UK. During the middle part of the 20th century manufacturers in other countries began production, with the first successful ones outside the UK being in Japan: Noritake , Nikko and Narumi. In more recent years production in China has expanded considerably, and the country is now the biggest producer of bone china in the world. Other countries producing considerable amounts of bone china are Bangladesh , , , [ citation needed ] , and . From the start of the first factory, Bengal , in , bone china output from Indian factories had risen to 10, tonnes per year by In Leningrad , USSR , the bone china recipe was invented independently, since it was not possible to get the finished recipe. This was achieved thanks to the special regime of firing thin-walled products from bone china, and all formulation developers received USSR State Awards. Lenox was the only major manufacturer of bone china in the United States [ citation needed ] , and has supplied presidential services to the White House. It closed production in the US permanently in March In the 21st century, "Islamic bone china" became available, using only bone ash from halal animals, as well as more conventionally clay and a high firing temperature.

Hand washing with a mild soap is strongly recommended. Handle only one piece at a time while washing and use care. Cup handles are the most prone to breakage. Some newer pieces may be marked dishwasher safe, but dishwasher detergents are very harsh and over time will fade the pattern on your good dishes. OIder bone china was painted and designed for gentle hand washing. There is also a possibility that even with the best dishwasher loading practice , these delicate items can become chipped simply from rattling against other dishes during the dishwashing process. If you do so you will see sparks that can damage both the china and your microwave. But don't be afraid to use your bone china—it is made to be enjoyed. Tea and coffee taste the best in bone china cups. Setting a table with this china gives it a touch of elegance, making the dinner more memorable and enjoyable.
