Porcelain sculptures are prized for their delicate beauty, but yellowing over time can diminish their appeal. Artists employ several strategies to combat this issue, ensuring longevity and aesthetic integrity.

First, selecting high-quality, low-iron clay is crucial. Iron impurities can oxidize and cause discoloration, so artists opt for premium white kaolin clay. The firing process also plays a key role; precise kiln temperatures and controlled oxidation environments prevent chemical reactions that lead to yellowing.

Glazing is another critical step. Non-reactive, lead-free glazes create a protective barrier against environmental pollutants and UV light, which can accelerate discoloration. Some artists even use nanotechnology-infused coatings for enhanced durability.

Storage and display conditions matter too. Keeping sculptures away from direct sunlight, humidity, and pollutants helps maintain their pristine appearance. By combining these techniques, artists ensure their porcelain creations remain luminous for generations.
