Tierra y Fuego Mexican ceramic sinks are handcrafted and handpainted by skillful artisans. The sinks are made of ceramic materials. Once the sink has been shaped with a mold, and dried at room temperature, it is fired in a kiln. Then it is glazed and decorated by hand and fired once again to give it its permanent and lustrous finish. Talavera ceramic colors and shine will not fade with proper care. We recommend NOT to use abrasive cleaners, as they may damage the glazed finish. As with any handcrafted item, our ceramic sinks will have small variations in color, design, size, and weight. Due to handcrafted nature of this item, a installation template is not provided. PLEASE NOTE: When installing the drain assembly be extra careful not to apply too much pressure, the drain hole may break.
