平顶山应国墓地出土原始瓷的制作工艺和产地

Technology and Provenance of Proto-Porcelain of Yingguo Graveyard in Henna Province

原始瓷一直是学术界所关心的重要问题,其产地和工艺关系到我国古代陶瓷发展模式以及商周文化面貌研究,具有十分重要的学术价值。采用XRF和XRD等科技手段,对最新出土的河南平顶山应国墓地遗址7枚原始瓷片进行了测试和产地推测。分析结果显示,应国墓地原始瓷瓷釉中磷含量明显偏高,暗示其使用了草木灰作为原料。与其他已发表的原始瓷数据相比,应国墓地出土原始瓷瓷釉的Ca/Al和P/Al值明显不同,暗示其配方工艺与南方产地产品有所差别。分析结果显示,应国墓地原始瓷产地不在南方。

Protoporcelain is a kind of multi-epoch and multi-culture-area ceramic hangover with iterative appearance, and it is the important interim of the development from pottery to porcelain. Therefore, its origin, development and prevalence problems, which relate directly to China development mode and Shang Zhou culture visage, are the important discussion of archaeology, ceramic technic history and chemistry history, and have important learning value. XRF and XRD technique were used to determine several shreds excavated from Yingguo graveyard site in Henan phosphor, hinting that some plant or wood ash was ever used as analysis, we discovered that proto-porcelain of Yingguo site has province. The result shows that some samples have ahnormity raw material. From the rate of Ca/A1 and P/A1 and comparative different chemical character compared to south production.
