For porcelain collectors, discerning between factory-produced pieces and artist-signed sculptures is crucial for valuation and authenticity. Key differences lie in craftsmanship details—artist-signed works often exhibit unique brushstrokes, subtle imperfections, and personalized glazing techniques absent in mass production. Signatures or chop marks are typically hand-painted with deliberate placement, while factory stamps appear uniform. Weight distribution and clay purity also vary, as artists frequently use premium materials. Provenance documentation and specialist appraisals further aid identification. Advanced collectors examine kiln marks and firing methods, as traditional artists often employ older techniques compared to industrial processes. Understanding these nuances helps preserve artistic legacy while avoiding misattributions in the collectibles market.
