Authenticating antique porcelain sculptures requires a keen eye for detail and an understanding of several critical indicators. One of the most telling signs is the presence of maker's marks or reign marks, often found on the base. These marks can reveal the era and origin of the piece, though forgers sometimes replicate them, so cross-referencing with historical records is essential.

Another key indicator is the aging process. Genuine antique porcelain develops fine hairline cracks, known as crazing, and a subtle patina over time. The glaze should show uneven wear, particularly in areas that would have been handled frequently. Modern reproductions often lack this natural aging.

The craftsmanship is also a vital clue. Authentic pieces exhibit precise hand-painted details, while fakes may show mechanical uniformity. Additionally, the weight and material composition can be telling—older porcelain tends to be lighter and made from purer clay. Advanced techniques like thermoluminescence testing can further verify age.

By examining these factors collectively, collectors can better assess the authenticity of antique porcelain sculptures and avoid costly mistakes.
