When it comes to sculpture, the choice of material significantly impacts the artwork's longevity and durability. Bronze sculptures are renowned for their permanence, often surviving centuries due to the metal's resistance to corrosion and environmental wear. Ancient bronze artifacts, for instance, still exist today, showcasing the material's enduring nature.

In contrast, paper and cardboard sculptures are far more ephemeral. While they offer flexibility and affordability, these materials are highly susceptible to moisture, tearing, and degradation over time. Paper sculptures may last a few decades under ideal conditions, but exposure to humidity or sunlight can drastically shorten their lifespan. Cardboard, though sturdier than paper, still lacks the resilience of bronze and is prone to warping or disintegration.

For artists seeking timeless pieces, bronze is the clear winner. However, paper and cardboard sculptures excel in temporary installations or experimental art, where impermanence is part of the creative expression. The choice ultimately depends on the artist's vision and the intended lifespan of the work.
