Artists employ a variety of sophisticated techniques to give newly made porcelain sculptures the appearance of age and historical significance. One common method involves applying patinas—thin layers of colored glaze or chemical solutions—to mimic the natural oxidation that occurs over centuries. Earth-toned washes of iron oxide or manganese dioxide can create subtle discoloration, while targeted applications of tea or coffee stains add organic-looking blemishes.

Another approach is intentional crackling, where artists induce fine surface fractures by applying specialized glazes that shrink at different rates during firing. Some even manually engrave hairline cracks before filling them with dark pigments to simulate centuries of wear. For dimensional aging, sculptors may carve or sand edges to appear worn, or add faux repairs like gold-filled "kintsugi" seams to suggest a storied past.

Modern ceramists also use controlled weathering techniques, such as burying pieces in acidic soil or exposing them to accelerated erosion processes. The most convincing aged porcelain combines multiple methods—layering textures, colors, and imperfections—to fool even expert eyes. These techniques not only preserve the fragility of real antiques but allow contemporary artists to explore themes of time and decay through their work.
