Evidence is presented that the clay in ancient ware fired at a temperature below 700–800°C becomes rehydrated over the millennia, such that it behaves somewhat like an unfired clay, rendering DTA a useful tool in identifying the clay minerals present. More recent samples can be artificially rehydrated by heating in a steam autoclave.
