Typical prehistoric pottery, called earthenware, requires temperatures between 900 and l,200°C (l,650-2,200°F) to vitrify. Fine porcelain pottery made from kaolin clay is fired at l,280-l,350°C (2,300-2,400°F) it is white and often translucent. A modem kitchen stove will produce temperatures ca. 260°C (500°F). An open wood fire produces temperatures in the range of 800-900°C (l,450-l,650°F). Closed kilns, a kind of oven, can reach temperatures of l,000°C (l,830°F) or more. Table 6.1 provides some information on firing temperatures, kiln conditions, and the type of ceramic produced. The conditions of firing determine the color of the pottery that is produced.
