What is Bone China?
Bone china is a delicate porcelain type first developed in England in the late 18th century. Josiah Spode is credited with the invention of bone china, combining bone ash with china clay and china stone to create a more durable and translucent material. Adding bone ash gave the Porcelain its signature whiteness, making it more robust and less prone to chipping. Since its inception, bone china has been synonymous with elegance and high quality, becoming a popular choice for fine tableware and decorative items.
Bone china is known for its brilliant white color, translucence, and exceptional strength. It is lighter and more delicate in appearance than other types of Porcelain but is also more durable, making it ideal for both everyday use and special occasions. Making bone china involves using calcined bone ash combined with china clay and china stone, then fired at high temperatures to create a vitrified, glass-like material. This results in Porcelain being resistant to chipping, cracking, and staining while showcasing intricate designs and patterns.
What is Bone China made of?
The Production Process of Bone China includes four primary steps listed below:
Raw Materials and Preparation
The primary raw materials used to produce bone china are bone ash, china clay (kaolin), and china stone (feldspathic material). Bone ash constitutes 30-50% of the final product and is derived from animal bones thoroughly cleaned, calcined, and ground into a fine powder. The bone ash, china clay, and china stone are mixed with water to form a liquid slip, which is the basis for the molding process.
Molding and Shaping
The liquid bone china slip is poured into porous plaster molds, which absorb the water and cause the slip to solidify, forming the desired shape. Once the piece has reached the desired thickness, the excess slip is poured out, and the remaining clay is left to dry until it can be easily removed from the mold. After removal, the piece is carefully inspected for any imperfections, which are smoothed out or repaired before moving on to the next production stage.
Firing and Glazing
Bone china undergoes multiple firings throughout its production process. The first firing, known as the “biscuit firing,” occurs after the pieces have been molded and dried. This firing, which occurs at temperatures of approximately 1200-1300°C, hardens the bone china and removes any remaining moisture. After the biscuit firing, the pieces are glazed with a mixture of liquid glass and water, which is applied as a thin layer over the surface. The glazed pieces are then fired again, this time at temperatures of around 1050-1100°C, which causes the glaze to fuse with the bone china, creating a smooth, glassy surface.
Decoration and Final Firing
Once the pieces have been glazed, they are ready for decoration. Various techniques, such as hand painting, transfer printing, or gilding, can apply intricate designs and patterns to bone china. After the decoration, the pieces undergo a final firing, known as the “glost firing,” at temperatures around 800-850°C. This firing helps to set the decoration and ensure its durability, resulting in the final product’s beautiful, lustrous finish.

Bone China vs. Porcelain: Understanding the Differences
Composition and Manufacturing Process
Bone china and Porcelain have distinct differences in composition and manufacturing processes while similar in appearance. Bone china is made by mixing bone ash, derived from animal bones, with clay and kaolin, a type of clay mineral. This mixture gives bone china its characteristic clarity and strength. Conversely, Porcelain is made from a mix of clay, kaolin, and feldspathic material. The primary difference in manufacturing is that bone china is fired at a lower temperature than Porcelain, resulting in a slightly softer and more delicate material.
What is the difference between Bone China and Porcelain?
Both bone china and Porcelain are known for their beauty and elegance, but there are subtle differences in their appearance, durability, and weight. Bone china is typically thinner and more translucent than Porcelain, with a warmer, ivory hue. Its delicate appearance may give the impression that it’s fragile; however, bone china is surprisingly robust and durable due to its unique composition. Conversely, Porcelain is heavier and more opaque, with a cool, white tone. While Porcelain is also durable, it’s not as lightweight or translucent as bone china.
