The alchemy of fire: Wood kiln vs. Electric kiln in ru ware
1. Temperature dynamics & glaze effects • wood kiln - firing curve: 72-hour nonlinear firing (±30°c swings) - key reaction: Agate molecules crystallize unevenly → frost fingerprints™ - color depth: 3d "Sky-after-rain" Gradient (pantone 19-4052 tcx → 16-5421 tcx)...
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°C • Agate particles create localized stress points...
How to Cultivate Ru Ware Teacups for Enhanced Frost Veins
1. Tea Selection Principles - Optimal Types: • Fully-oxidized teas (e.g. Pu-erh, Black Tea) • Mineral-rich varieties (Wuyi Rock Tea, Aged White Tea) - Avoid: • Green/light oolongs (low tannin content) • Flavored/scented teas (chemical interference) 2. Brewing Methodology...
How to Choose a Premium Ru Ware Teacup
1. Glaze Quality Color: Look for the signature "sky-after-rain" celadon (Pantone 19-4052 TCX). Avoid dull or overly uniform hues. Texture: Surface should resemble cracked ice (not sharp cracks) – fine "frost veins" that feel smooth to touch. 2. Kiln Type...
The History and Evolution of Ru Ware Celadon
1. Origins (Northern Song Dynasty: 960-1127 AD) - Imperial Commission: • Founded circa 1086 under Emperor Huizong's decree • Exclusive to royal court for 40 years (1086-1126) - Legendary Standard: • "Sky-after-rain" glaze color mandated by imperial poem • Only...
