The decision to repair or replace a damaged porcelain sculpture depends on several critical factors. First, the extent of the damage plays a significant role. Minor cracks or chips may be easily repaired, while severe breaks or missing pieces might necessitate replacement.

Second, the historical or sentimental value of the piece is crucial. Antique or emotionally significant sculptures often warrant professional restoration to preserve their original integrity. Conversely, mass-produced items may not justify the cost of repair.

Third, financial considerations come into play. Restoration can be expensive, especially for intricate pieces requiring specialized expertise. Weighing the repair costs against the sculpture's market value helps determine the most practical option.

Lastly, the availability of skilled artisans is a factor. High-quality restoration requires experts in ceramic art conservation, and their scarcity might limit repair feasibility.

Ultimately, the choice between repair and replacement balances artistic, emotional, and practical considerations to ensure the best outcome for the porcelain sculpture.
