Porcelain is a type of hard semi-translucent ceramic generally fired at a high temperature.
Porcelain is typically biscuit fired at around 1000 degrees Celsius (1800 degrees Fahrenheit), and glaze fired (the final firing) at 1300°C (2300°F) or higher.
Porcelain clays can be chemically formulated for strength, plasticity and durability to the point that they can be used as throwing bodies. Porcelain ware was produced on the potter’s wheel in many historic cultures, including China and Japan. Many categories of glazes, e.g. celedons, were formulated specifically for their striking effects on porcelain. Modern potters also produce porcelain ware, and generally believe these clay bodies challenge production, firing and glazing skills. Commercially formulated procelain bodies are generally available through most clay distributors.
