Wood carvings are beautiful art pieces that require proper care to prevent splitting and cracking over time. Here are the most effective methods to keep your wooden artwork in pristine condition:

1. Choose the Right Wood: Start with stable, properly seasoned wood like teak, oak, or walnut that's less prone to splitting. Avoid woods with high moisture content or visible cracks.

2. Proper Sealing: Apply multiple coats of quality sealant (like polyurethane or linseed oil) to create a protective barrier against moisture changes. Sand between coats for optimal absorption.

3. Control Humidity: Maintain consistent humidity levels (40-50% RH) where carvings are displayed. Use humidifiers or dehumidifiers as needed to prevent rapid wood expansion/contraction.

4. Gradual Drying: For new carvings, allow slow, even drying in a shaded, well-ventilated area. Cover with plastic initially, then gradually expose to air over weeks.

5. Regular Maintenance: Dust carvings gently and reapply protective finishes annually. Inspect for early signs of cracking to address issues promptly.

6. Avoid Direct Sunlight: UV rays accelerate drying and cracking. Display carvings away from direct sunlight or use UV-protective window films.

7. Proper Storage: When not displayed, wrap carvings in breathable fabric and store in climate-controlled spaces with stable temperatures.

By implementing these preventive measures, you can significantly extend the life of your wood carvings and maintain their artistic integrity for generations to come.
