A vintage copper mold shaped like a cluster of grapes.

Copper molds, particularly those shaped like fruits and vegetables, were popular in the 19th and 20th centuries for baking cakes, jellies, and aspics. Their excellent heat conductivity made them ideal for even baking, and their decorative nature meant they could also serve as attractive kitchen displays. Many were crafted by skilled artisans, often in Europe, and featured intricate designs that showcased the culinary and decorative trends of their time.
