在大姚县凤洞岩窑遗址的明初层出土了大量刻有“关”或“龙”图案的龙泉瓷片。这些青瓷碎片是在明朝洪武和永乐年间烧制的。采用能量色散x射线荧光（EDXRF）对85块典型官窑瓷器的原料和烧制工艺进行了分析。结果表明：红武时期和永乐时期矿体中TiO2和Fe2O3含量存在差异；明初御瓷釉中K2O、Fe2O3和TiO2的平均值高于南宋龙泉釉，CaO的平均值低于南宋龙泉釉。主成分分析（PCA）表明，同一种原料的不同淋洗度是洪武和永乐时期这种差异的主要原因。然而，官窑釉的原料并没有明显的变化，并继承了早期的传统。明初御用瓷器的制作和烧制技术达到了较高的水平，并没有下降。
A mass of Longquan porcelain shards carved with Guan' or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy-dispersive X-ray fluorescence (EDXRF). The results indicate that the contents of TiO2 and Fe2O3 in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K2O, Fe2O3 and TiO2 are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.
