Porcelain sculptures are admired for their delicate beauty, but they are also prone to several common flaws due to their fragile nature. The most frequent defects include cracks, glaze imperfections, warping, air bubbles, and discoloration.

Cracks often occur during the firing process or due to physical stress. Experts detect them through visual inspection, UV light, or tapping tests to identify hidden fractures. Glaze defects, such as pinholes or uneven coatings, are visible under magnification or bright light. Warping, caused by uneven drying or firing, is checked using flat surfaces or laser measurements.

Air bubbles trapped during molding may weaken the structure and are spotted via X-ray imaging. Discoloration from improper firing or aging is assessed under controlled lighting. Professional restorers use these methods to evaluate and preserve porcelain sculptures, ensuring their longevity and aesthetic appeal.

Understanding these flaws helps collectors and artists maintain the integrity of these exquisite artworks.
