Andrea Della Robbia was a follower of the style of early Italian Renaissance art pioneered by his uncle, Luca. This very unique style focused on the use of glazed terra cotta to create enameled reliefs and other sculptural pieces, and Andrea is known by art historians as the most prominent ceramic artist of the era. Thus, his family will always be remembered in the art history world for the first answer, their "distinctive glazes and ceramic production".
