What are the differences between using heartwood and sapwood in teak outdoor sculptures?

When crafting teak outdoor sculptures, understanding the differences between heartwood and sapwood is crucial for durability and aesthetics. Teak heartwood, the inner part of the tree, is highly prized for its rich golden-brown color, natural oils, and exceptional resistance to rot, insects, and weathering. These qualities make it ideal for long-lasting outdoor art. In contrast, sapwood, the outer layer, is lighter in color, less dense, and lacks the same level of natural protection, making it more susceptible to damage over time.

Heartwood's superior durability comes from its higher concentration of oils and resins, which repel moisture and pests. Sapwood, while still usable, often requires additional treatments or sealants to match heartwood's performance. Artisans may blend both for cost efficiency, but pure heartwood sculptures command higher value due to their longevity and premium appearance.

For outdoor sculptures, heartwood is the preferred choice, ensuring minimal maintenance and timeless beauty. Sapwood can be used for less critical elements or indoor pieces where environmental exposure is limited. Choosing the right wood type ultimately depends on budget, desired lifespan, and artistic vision.
