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°C   • Agate particles create localized stress points...
