The fragments of unfinished vases which have been found from time to time[24] have been used as evidence to prove several glaze fires; for they show fired vases at a definite stage in the glazing, the outlines and inner markings painted, but the background not yet filled in. Must we, then, suppose that it was the regular practice—at least in the later red-figured period to which all the unfinished pieces belong—to fire before and after the painting of the background? It is difficult to see what would be gained by the process. If the pottery were fired before any decoration was applied, there would be the advantage of safer handling of the ware; but to have an extra firing with the decoration more than half completed gives no apparent gain and there is the distinct disadvantage of the extra expense of firing.
