The shelf life of a porcelain sculpture depends on several critical factors, each contributing to its longevity and preservation.

1. Material Quality: High-grade porcelain with refined clay and proper firing techniques ensures durability. Inferior materials may crack or discolor over time.

2. Glazing and Finishing: A well-applied glaze protects against moisture and wear. Poor glazing can lead to chipping or fading.

3. Environmental Conditions: Exposure to humidity, temperature fluctuations, and direct sunlight can weaken porcelain. Stable, dry environments are ideal.

4. Handling and Maintenance: Rough handling increases fracture risks. Regular dusting and careful storage extend lifespan.

5. Chemical Exposure: Harsh cleaners or pollutants can degrade surfaces. Gentle cleaning methods are recommended.

By addressing these factors, collectors and artists can significantly prolong the life of porcelain sculptures, preserving their artistic and monetary value for generations.
