Maintaining the structural integrity of large porcelain sculptures presents unique challenges due to the delicate nature of the material and the scale of the artwork. One primary issue is the inherent fragility of porcelain, which is prone to cracking or breaking under stress, especially in large, unsupported sections. The weight distribution of these sculptures also poses a significant challenge, as improper balance can lead to structural failures over time.

Environmental factors such as temperature fluctuations, humidity, and exposure to sunlight can cause expansion, contraction, or discoloration, further compromising the sculpture's stability. Additionally, the firing process itself can introduce weaknesses if not meticulously controlled, with uneven heating or cooling leading to internal stresses.

Transportation and installation of large porcelain sculptures require extreme care, as any sudden movement or impact can cause irreparable damage. Conservators must also address long-term wear, including surface erosion and micro-fractures, which can develop over years of display.

Innovative techniques, such as reinforced internal frameworks and advanced adhesives, are being developed to address these challenges. However, the balance between structural support and aesthetic preservation remains a delicate art in itself. Understanding these challenges is crucial for artists, collectors, and conservators working with these magnificent but demanding artworks.
