Creating interlocking porcelain sculpture components requires meticulous precision, yet artists and craftsmen often face significant challenges. One major issue is material shrinkage during firing, which can distort shapes and disrupt alignment. Porcelain's delicate nature also makes it prone to cracking or warping, complicating the assembly of intricate designs.

Another challenge lies in the design complexity itself. Interlocking components demand exact measurements and tolerances, leaving little room for error. Even minor deviations in mold-making or hand-sculpting can result in ill-fitting pieces. Additionally, the glaze application process can alter dimensions slightly, further affecting alignment.

Techniques like slip casting or 3D modeling can help mitigate these issues, but they require advanced skills and equipment. Ultimately, achieving perfect alignment in porcelain sculptures demands a blend of technical expertise, patience, and iterative testing to overcome these common hurdles.
