Tlalpan Blue on White is part of the Valle Ware category of majolica that was made in Mexico City during the second half of the sixteenth century. Valle Ware is considered to be a cheap, lower quality version of the Mexico City Wares described by Lister and Lister (1982:30). It differs from the Mexico City Wares in its sandier, redder paste, and poor quality of craftsmanship and glaze application. Tlalpan Blue on White is reminiscent of the contemporary Sevillian Yayal Blue on White in its emphasis on banding.
Coarse, sandy brick-red paste. Moderately thick off-white tin enamel, that is thinner on reverse of vessels. The glaze is highly subject to crazing, pinholing, and crawling. Decoration is limited to blue lines or bands encircling the vessels below the rim, and around the central area.
