Creating porcelain sculptures with iridescent finishes is a delicate art form that demands precision and expertise. One of the most common challenges is achieving consistent glaze application, as uneven layers can disrupt the iridescent effect. Additionally, the kiln firing process must be meticulously controlled, as temperature fluctuations can alter the final appearance. The fragility of porcelain also poses difficulties, as intricate designs may crack under stress. Lastly, sourcing high-quality materials that react predictably to glazes is essential but often challenging. Mastering these obstacles requires patience, skill, and a deep understanding of ceramic chemistry.
