Porcelain sculptures are delicate artworks that require meticulous attention to glaze stability, especially in high-humidity environments. Artists employ several advanced techniques to prevent glaze deterioration, ensuring longevity and aesthetic appeal.

One common method is using humidity-resistant glazes formulated with silica and alumina, which create a durable, non-porous surface. These glazes minimize moisture absorption, reducing the risk of cracking or discoloration. Additionally, artists may apply multiple thin layers of glaze, allowing each to dry thoroughly before firing, which enhances adhesion and resilience.

Controlled kiln firing is another critical step. By carefully adjusting temperature and cooling rates, artists ensure the glaze bonds securely to the porcelain body, preventing moisture-related defects. Some even use post-firing treatments like wax sealing or resin coatings for extra protection in humid climates.

Environmental controls in studios, such as dehumidifiers and proper storage, further safeguard finished pieces. Through these innovative approaches, artists successfully preserve the beauty and integrity of porcelain sculptures, even in challenging conditions.
