Light, pristine, dainty and visually appealing, Bone China is the dream of every crockery lover. Bone China has long been associated with sophistication, from a delicately painted teacup passed down the generations to an elegant dinner set kept for special occasions or a lavish wedding gift. Its translucent glow, its feather-light weight and its remarkable strength have earned it a place in homes, royal collections and fine-dining restaurants the world over. But beyond its shiny veneer lurks a question that catches many first-time buyers off guard: Is Bone China really made of animal bones? Specifically, is it true that Bone China crockery contains 50 percent animal bones?And the answer is- yes, but to a certain degree. Traditional Bone China does contain bone ash from animal bones, but the percentage can vary by manufacturer. Many traditional formulations have between 30% and 50% bone ash, but there is no hard-and-fast rule that every Bone China product must have exactly 50%. Here’s all you need to know about one of the planet’s most intriguing ceramic materials.According to experts, Bone China is a type of porcelain that differs from traditional porcelain because it contains bone ash in addition to clay minerals. A traditional Bone China body generally comprises three main ingredients: bone ash, China clay (Kaolin), and feldspar.The main ingredient is bone ash, which is made by heating animal bones to a very high temperature until all organic material has burned off, leaving a white mineral powder that is mostly calcium phosphate.This bone ash gives Bone China its famous combination of whiteness, translucency and exceptional strength, as stated by the International Ceramics Studio and ceramic manufacturing references.The fact is: Yes.
Traditional Bone China contains calcined bone ash, usually derived from cattle bones as a by-product of the meat industry. However, the claim that Bone China always contains 50% animal bones is not true. Traditional recipes generally require 30-50% bone ash by weight. Many premium manufacturers use around 40-45% bone ash in their formulation. The rest is china clay and feldspar. It is also important to understand that bone ash is not raw bone. In production, the bones are cleaned and fired at temperatures often over 1,000°C destroying organic material and leaving only mineral compounds. Then these minerals are ground very fine and mixed into the ceramic.According to legends, bone ash has been around since 18th-century England. Back then, potters wanted a ceramic that was as beautiful as the porcelain imported from China but also more durable. Adding bone ash yielded extraordinary results.It is said that bone ash helps attain an unprecedentedly white, warm ivory shade, and also provides superior translucency, improved chip resistance and enhanced mechanical strength. This makes Bone China both elegant and practical.For the uninitiated, bone China was developed in England in the latter part of the 18th century. In the early days, potters experimented with adding calcined animal bone to porcelain recipes and eventually developed a substance that was stronger and more translucent than many other ceramics. By the nineteenth century, Bone China was a hallmark of British craftsmanship. Tableware was supplied to aristocratic households, luxury hotels and royal families by prestigious manufacturers.Bone China is still made in a number of countries today, although the techniques of manufacture have changed considerably.For the uninitiated, they both belong to the ceramic family but there are obvious differences. Bone China is made from bone ash, usually from calcined cattle bones, mixed with kaolin and feldspar, which gives it a warm ivory colour, excellent translucency and a thin but incredibly strong composition.
