What temperature is porcelain typically fired at?

Porcelain is typically fired at extremely high temperatures, which is essential for achieving its characteristic strength, translucence, and low porosity. The standard firing temperature for porcelain usually ranges from about 1200 degrees Celsius to around 1400 degrees Celsius. However, some types of porcelain can indeed be fired at temperatures reaching up to 1800 degrees Celsius, which allows for unique properties and finishes.

Firing porcelain at this elevated temperature ensures that the feldspar in the clay melts slightly, allowing the other materials to fuse together effectively. This process also contributes to the distinct glass-like quality that characterizes well-made porcelain.

While there are other firing ranges mentioned in the options, they do not correspond to the standard practices associated with porcelain production. Low firing temperatures, under 1000 degrees Celsius, are typically associated with earthenware or stoneware rather than porcelain. Therefore, firing porcelain at approximately 1800 degrees Celsius is correct as it reflects the upper end of the temperature range utilized for achieving the desired material properties in fine porcelain artworks and ceramics.
