Creating porcelain sculptures for underwater or submerged displays presents unique artistic and technical challenges. The first major hurdle is material durability—porcelain, while elegant, is inherently fragile and susceptible to cracking or erosion in aquatic environments. Prolonged exposure to water pressure, salinity, and temperature fluctuations can compromise structural integrity over time.

Another critical issue is buoyancy control. Porcelain's density requires careful balancing to prevent floating or shifting, often necessitating weighted bases or anchoring systems that blend seamlessly with the artwork. Marine growth like algae and barnacles also poses aesthetic and preservation challenges, potentially obscuring intricate details or accelerating deterioration.

Environmental considerations add complexity. Artists must ensure materials and glazes are non-toxic to avoid disrupting delicate aquatic ecosystems. Additionally, installation logistics—such as depth adjustments for light refraction and visibility—demand meticulous planning. Despite these obstacles, underwater porcelain sculptures offer mesmerizing possibilities, merging artistry with the dynamic beauty of marine settings.
