历代龙泉青瓷釉的初步研究

龙泉窑是我国陶瓷生产业中最重要的窑场之一，其制瓷业有着一千多年的发展历史。现代仿古龙泉青瓷的生产水平也达到了一定高度。为研究不同时代龙泉青瓷产品的特征，特采集一组宋、元、明及现代龙泉青瓷样品，通过显微观察、色度测定及对瓷釉的主量、微量化学组成进行X荧光分析，实验数据分析表明龙泉青瓷釉的制作有一定的年代特征，宋早期青瓷釉中存在石灰釉产品，而南宋以后，龙泉青瓷釉逐渐成为石灰碱釉。现代仿古龙泉青瓷的主量化学组成与古龙泉青瓷有很大相似性，但微量组成的不同反映出在原料配方上还存在很大差异。分析结果将为龙泉青瓷的研究与鉴定提供部分借鉴和依据。

Preliminary study on the glazes of Longquan celadons

Longquan kiln is one of the most important ancient kilns in China,it lasted for more than one thousand years.Now the reproduction of Longquan celadons in local area is also very popular.In order to find the characteristic of Longquan products from different ages,a set of Song,Yuan,Ming and modern Longquan celadons were collected,by means of microstructure observation,color measurement and chemical composition analysis,some preliminary conclusions were obtained:calcium glaze was used for celadon production in early Song Dynasty,from Southern Song Dynasty,content of K_2O was increased gradually,finally glaze became to be calciumkalium glaze.Modern Longquan celadons has almost the same content in major elements with those ancient Longquan celadons,but the trace elements' contents are quite different.This work will provide some useful information for the study and appraisal of Longquan celadons.
