Matt outside, glazed inside. Pinto Pottery or Unmarked Niloak Mission Ware Vase 6.5", Per Collectors Weekly: Pinto Pottery was the precursor to Desert Sands Pottery. It existed in Boulder City, Nevada beginning in 1946 and lasted only until 1949 when ownership was re-organized and the pottery was renamed Desert Sands. .... As far as I know, Pinto never glazed the exterior of their ware but often the interiors were glazed. Exterior glazing was a development that came about after they became Desert Sands.
