Ancestral Puebloan potters made Tusayan White Ware pottery on and around Black Mesa, near the present day Hopi villages, from about A.D. 600 to 1300. They used iron-poor clays, quartz sand temper, and organic paint. Different design styles appear in different time periods. This type, Dogoszhi Black-on-white, was made from about A.D. 1040 to 1200. Designs have parallel thin lines called "hatchure" and thin framing lines. Lines are almost always 2 to 3 mm thick.
