数据范围 Scope
本表综合三项学术来源的分析化学数据，对比德化（明代胎）、景德镇（甜白釉胎）、定窑（宋代胎）、梅森（早期硬质瓷）四大白瓷产区的胎体化学成分。 数据以重量百分比（wt%）表示，每个数值为相关文献中同一产区多个样本的测量范围。
This table synthesizes analytical chemistry data from three academic sources, comparing the body composition of white porcelain from four major production centres: Dehua (Ming dynasty body), Jingdezhen (sweet white glaze body), Ding (Song dynasty body), and Meissen (early hard-paste). Values are expressed in weight percent (wt%), representing the measured range across multiple samples in the referenced literature.
四大产区化学成分对比 Four-Region Comparison
| 成分 Component | 德化（明代胎） Dehua (Ming) | 景德镇（甜白釉胎） Jingdezhen | 定窑（宋代胎） Ding (Song) | 梅森（早期硬质瓷） Meissen |
|---|---|---|---|---|
| SiO₂ Silicon dioxide | 71.8–74.2% | 70–75% | 64–68% | 65–70% |
| Al₂O₃ Aluminium oxide | 15–18% | 18–23% | 25–30% | 24–28% |
| K₂O Potassium oxide | 6.5–7.3% | 3–4.5% | 2.5–4% | 1–2% |
| Fe₂O₃ Iron(III) oxide | <0.5% | 0.8–1.5% | 1–2% | 0.5–1% |
| Na₂O Sodium oxide | 0.3–0.8% | 0.5–1.5% | 0.5–1% | 2–4% |
| CaO Calcium oxide | 0.5–2% | 1–5% | 2–5% | 1–3% |
Key differentiators (bold): K₂O 6.5–7.3% (3–7× higher than other regions) promotes glass phase formation and translucency; Fe₂O₃ <0.5% permits oxidation firing, yielding a warm white tone without reduction atmosphere control.
