一、早期青瓷釉色的化学特征1.现在看到的早期青瓷的釉色东汉青瓷和春秋至西汉原始瓷相比有了重大进步。吸水率只有0.3%,烧成温度约为1260-1310℃。东汉青瓷的产地主要在浙江宁绍平原、金华丘陵和永嘉沿海地区。而北方则是从北魏时起,黄堡镇瓷器就已具规模。这些早期青瓷瓷土含铁量比较高,采用石灰釉,釉料中含氧化钙达15%以上,釉层较薄。由图1-4可见,我们现在看到的早期青瓷无论
First, the chemical characteristics of the early celadon glaze 1. Now see the early celadon glaze Eastern Han celadon and the Spring and Autumn to Western Han Dynasty compared to the original porcelain has made significant progress. Water absorption is only 0.3%, firing temperature is about 1260-1310 ℃. Eastern Han celadon origin mainly in Zhejiang Ning Shao plain, Jinhua hills and Yongjia coastal areas. The north is from the Northern Wei Dynasty, Huangpu porcelain has been with the scale. These early celadon porcelain soil iron content is relatively high, the use of lime glaze, glaze containing calcium oxide up to 15%, glaze thin. As can be seen from Figure 1-4, the early celadon we now see no matter
