San Luis Blue on White is part of the Mexico City "Fine Ware" majolica category, and is thought to date to the second half of the sixteenth century. It does not appear regularly in Florida or Caribbean contexts until after about 1575. The cream-colored paste is a later phenomenon, and occurs in examples dating to the seventeenth century.

This description of San Luis Blue on White comes from the Historical Archaeology Digital Ceramic Type Collection maintained by the Florida Museum of Natural History.

Paste is dense with little visible mineral tempering, and is usually orange-red in color. Cream-colored paste occurs on later examples. Background enamel is thick, reflective and off-white, sometimes with a grayish tint. It has a tendency to craze and pinhole. Decoration is painted in two shades of grayish-blue. The blue paint is often thick and slightly raised in relief on the surface of vessels. Motifs include large, stylized floral elements and leafs, sets of thin curved lines, dots, half circles and lobes.
