What role does cedar’s tannin content play in natural weathering processes of outdoor sculptures?

Cedar wood, prized for its durability and rich tannin content, plays a significant role in the natural weathering of outdoor sculptures. Tannins, organic compounds found in cedar, interact with environmental factors like sunlight, rain, and oxygen to create a protective patina. This process slows decay by resisting fungal growth and insect damage while deepening the wood's color over time. The tannins also react with metal fixtures, often producing striking streaks that add character to the artwork. Understanding this natural chemistry helps artists select materials that age gracefully, blending art with nature's transformative power. Properly maintained cedar sculptures can endure decades, their evolving appearance telling a story of interaction between craftsmanship and the elements.
