The lifespan of a porcelain sculpture depends on several critical factors that collectively determine its durability and preservation potential. First and foremost, the quality of materials used in creation plays a fundamental role. High-grade kaolin clay and proper firing techniques result in denser, more durable pieces that withstand the test of time better than inferior quality alternatives.

Environmental conditions represent another crucial factor. Porcelain is particularly sensitive to temperature fluctuations, humidity levels, and direct sunlight exposure. Ideal preservation requires stable environments with moderate humidity (around 50%) and protection from UV rays that can fade colors and weaken the material over decades.

The sculpture's structural design significantly impacts longevity. Pieces with delicate, protruding elements or thin sections are more vulnerable to breakage compared to more robust designs. Historical pieces that have survived centuries often feature balanced proportions and thoughtful weight distribution.

Proper handling and maintenance practices dramatically affect lifespan. Regular dusting with soft brushes, careful transportation methods, and immediate repair of any chips or cracks can extend a sculpture's life substantially. Professional restoration when damage occurs prevents further deterioration.

Finally, the original glaze quality and subsequent surface treatments influence durability. Intact glaze acts as a protective barrier against environmental factors, while compromised surfaces accelerate aging. Understanding these factors helps collectors and artists alike preserve these delicate artworks for generations to come.
