Restoring or repainting antique porcelain sculptures requires meticulous care, as improper techniques can lead to irreversible damage. One primary risk is material incompatibility—modern adhesives or paints may chemically react with aged ceramics, causing cracks or discoloration. Over-cleaning can strip original glazes, while aggressive handling might fracture fragile sections. Additionally, excessive repainting obscures historical authenticity, drastically reducing the piece's value. Color matching is another challenge; mismatched hues distort the artist's intent. Environmental factors like humidity shifts during restoration may also trigger hidden stresses. Ultimately, poorly executed interventions risk transforming a treasured artifact into a mere replica. Experts emphasize minimal intervention and documentation to preserve both physical integrity and provenance.
