The consistency of porcelain sculptures is highly sensitive to environmental conditions during production. Factors like temperature fluctuations, humidity levels, and air quality can significantly alter the final product.

1. Temperature Control: Porcelain requires precise kiln temperatures (typically 1200–1400°C) for proper vitrification. Inconsistent heat can cause cracks, warping, or incomplete sintering. Sudden temperature changes may lead to thermal shock, weakening the structure.

2. Humidity Impact: High humidity slows drying, increasing the risk of deformation, while low humidity may cause uneven shrinkage. Controlled moisture levels ensure uniform clay plasticity and prevent defects like crazing.

3. Airflow & Dust: Poor ventilation introduces impurities, affecting glaze adhesion. Dust particles can create surface blemishes, reducing aesthetic quality.

4. Seasonal Variations: Winter dryness and summer humidity demand adjusted production techniques to maintain consistency year-round.

Optimal conditions involve climate-controlled studios with stable humidity (40–60%) and minimal airborne contaminants. Mastering these factors ensures durable, high-quality porcelain sculptures with uniform finishes.
