摘 要:本文对龙泉务辽金代白瓷和黑瓷进行了研究,其胎的组成以高铝(3.2~38.5%)、钠(1.2~4.2%)和低硅(52.9~55.5%)为特征,其组成与北方古代名窑瓷胎有明显差别。样品釉的组成差别较大:一个样品属碱钙釉;三个样品属钙碱釉;二个样品属钙质釉。酱色釉是在强氧化气氛下烧成,放在黑釉表面形成一层赤铁矿结晶体,使其釉的外观呈酱红色。细白瓷样品的烧成温度为1240℃左右。In this paper, some Longquanwu white porcelain and black porcelain shards were studied. Their compositioncharacteristics of the body are high in Al2O3(32 .2 ~ 38. 5 % ) and Na2O(1. 2 ~ 4. 2 % ) contents and low of SiO2 con-tent (52. 9 ~ 55. 5 % ). Their chemical compositions of the body are different from those of northern famous ancientporcelain. Their compositions of the glaze are different: one sample is alk - Ca - glaze, three samples are Ca - alk -glaze and two samples are Ca - glaze. A thin layer of the hematite crystallite was formed on the surface of a blackglaze because the sample was fired at the strong oxidizing atmosphere. So the appearance of the sample appears indark reddish brown color. The firing temperature of the fine white porcelain sample is about 124Ot.
