Talavera arrived in Mexico with Spanish potters in the sixteenth century and never left — Moorish geometry carried through Andalusia, rendered in cobalt, saffron and deep green on a white ground. Three centuries later, California borrowed the same vocabulary for its Spanish Revival houses and rendered it differently: softer earth tones, and a raised cuerda seca line that gives the pattern real relief.
Both are still made by hand in the same Mexican workshops. Every piece is formed, painted or glazed, and fired in small batches, which is why colour depth and edge shift from tile to tile. Pattern collections are sold by the piece so a border or riser takes exactly the count it needs; solid collections are the ground those patterns were designed to sit against.
