What characterizes cloisonné work?

Cloisonné work is characterized by the decorative technique that involves creating compartments (or "cloisons") using strips of metal wire, typically gold or copper, which are then filled with colored enamel or gemstones. This method produces vibrant designs with distinct boundaries, allowing for intricate patterns and details that are a hallmark of cloisonné art.

The use of wire to separate materials is essential, as it not only defines the individual sections of the design but also contributes to the structural integrity of the piece. This technique has been prominent in various cultures, particularly in Byzantine and Asian artworks, where it has been employed to create jewelry, decorative objects, and religious artifacts.

In contrast to the other choices, floral designs in paintings, carving into stone, and painting on canvas do not pertain to the specific technique of cloisonné, which is focused on the combination of wiring and enameling or gemsetting.
