Creating an authentic distressed or weathered appearance on porcelain sculptures requires specialized techniques that mimic natural aging processes. Here are five professional methods used by ceramic artists:

1. Crackle Glazing: Applying a special glaze that intentionally cracks during firing creates an instant antique effect. The cracks can be enhanced with pigments rubbed into the fissures.

2. Dry Brushing: Using minimal paint on a dry brush to lightly highlight raised areas creates natural-looking wear patterns that suggest age and handling.

3. Oxidation Staining: Applying iron oxide or other metal solutions before firing produces subtle discoloration that resembles centuries of environmental exposure.

4. Controlled Chipping: Carefully chipping edges with specialized tools followed by smoothing creates believable wear without compromising structural integrity.

5. Patina Development: Layering multiple thin washes of colored slips creates depth and complexity similar to naturally aged surfaces.

Each technique requires practice to master the balance between artificial aging and maintaining the sculpture's artistic integrity. Many artists combine several methods for the most convincing results. The key is studying genuine antique porcelain to understand how materials naturally degrade over time.
