The bole-red color that made Iznik ceramics renowned was introduced in around 1560. In contrast to the other colors; which are traditional glaze pigments; this red is a slip that is frequently found in slight relief under the sparkling transparent glaze; another characteristic of the best products from Iznik. Local Turkish flora; with flowering cherry branches and roses; grace these tiles in an elegant manner. The tiles would have framed the opening to a little niche hollowed out of a wall.
