While visual inspection is a common way to judge porcelain sculptures, true craftsmanship assessment requires deeper techniques. Here are expert-recommended methods to evaluate quality beyond aesthetics:

1. Tactile Evaluation: Run your fingers along the surface to detect inconsistencies. High-quality porcelain should feel uniformly smooth, with no rough patches or uneven glazing.

2. Sound Test: Gently tap the sculpture with a fingernail or soft object. Fine porcelain produces a clear, resonant ring, while lower-quality pieces sound dull or hollow.

3. Weight Distribution: Well-crafted sculptures have balanced weight. Lift and handle the piece to check for awkward heaviness or instability, which may indicate poor construction.

4. Material Analysis: Examine the clay body's purity and density. Authentic porcelain is fine-grained and translucent when held to light, unlike cheaper ceramics.

5. Detail Inspection: Use magnification to assess intricate areas. Superior craftsmanship shows precise detailing without cracks, bubbles, or sloppy joins.

6. Thermal Conductivity: Porcelain retains temperature differently than imitations. Place your palm on the surface—genuine pieces feel cooler initially and warm gradually.

By combining these techniques, collectors and appraisers can accurately determine a porcelain sculpture's true craftsmanship level, ensuring informed acquisitions and proper valuation.
