Ribbed, three lines are most often seen on the handle of Chinese porcelain teawares. Three molded ribs on the exterior of a handle lie adjacent to one another. The three ribs can look at bit like a cockscomb.
The genre for this stylistic element depends on a combination of decorative technique, color, and element.
