What is the difference between porcelain and bisque?

Porcelain is created from a mix of specific materials that is then heated at between 2,200 and 2,600 degrees Fahrenheit. Kaolin is the primary material from which porcelain is made (although clay minerals might only account for a small proportion of the whole). Afterward, it is glazed to give a luxe finish. Unglazed porcelain is called bisque. Shop a range of antique and vintage porcelain items on 1stDibs.
