The Science Behind Ru Ware's Frost Veins ("Crackle Patterns")
1. Fundamental Causes - Thermal Stress: • Clay (α=5.4×10⁻⁶/°C) & glaze (α=7.1×10⁻⁶/°C) coefficient mismatch • Generated during cooling from 1300°C→200°C at ~15°C/min rate - Crystalline Growth: • Mullite (3Al₂O₃·2SiO₂) needles form at 1100-1250°...
