Four north coast Peruvian stirrup-spout jars of the middle Moche period show every indication of having been cast from a single mold. Heretofore no more than two actual duplicates from one mold have been described for pre-Columbian north coast pottery. This mold-made product varies from cast to cast in spout form, hue, paint distribution, polish, general surface texture, quality of mold-impressed lines, diameter measurements, and sharpness of relief. A second series of four similar Moche jars which were not from the same mold indicates that duplicates cannot be posivitely identified without careful firsthand examination of the specimens.
