Panel of 4 cuenca tiles
This panel of four tiles illustrates the persistence of Islamic design principles; however, the cuenca, or arista, technique, in which the colors are prevented from mingling in the firing process by raised borders molded in the clay, has replaced the earlier Islamic cuerda seca method, examples of which may be seen in the case to the left. The geometric pattern would have been repeated to cover a large area of wall or ceiling.
