This artiele deals chiefly with the effect of bass glasses, compossition of coloring agents.(S, Sb_2O_3, and C)and the minor -metallie oxides on the antimony ruby glass.The result of our investigation shows that it is possible to produce good ruby colour with SiO_2-CaO-ZnO-Na_2O as base glass by introducing (?)all quantlty of CuO without adding carbon as reducer.

本文重点研究基本玻璃,着色剂含量(S、Sb_2O_3、c),以及微量金属氧化物对銻红玻璃显色的影响。实验结果表明,以SiO_2-CaO-ZnO-Na_2O为基本玻璃,引入微量CuO,在不加入碳素等还原剂的情况下,可能制造出良好的銻红玻璃。

In these studies, several typical specimens of Chinese blue-and-white ware manufa-ctured in successive dynasties were collected and their chemical composition, microstru-cture, porosity and firing temperature were examined. In order to understand the different sources of cobalt ores used in the ancient Chine-se blue-and-white ware, and for the sake of comparison, the chemical composition ofseveral typical native cobalt ores were examined as well. From the results of chemical analysis, it was found that, (1) The native cobalt ores, almost without exception, contain a high percent of MnOand a low percent of CoO. This kind of cobalt ores is generally known as "asbolite". (2) For the blue pigment painted on the Northern-sung blue-and-white ware excava-ted in Chekiang province, the MnO/CoO and Fe_2O_3/CoO ratios are 10.25 and 0.61 respecti-vely, these values quite near those of the native cobalt ores. It is clear that the blue pig-ment used in this period was native cobalt ore. (3) For Yuan blue-and-white ware, the MnO/CoO and Fe_2O_3/CoO ratios are 0.01~0.06and 2.21~3.02 respectively. The ratios among the five specimens under investigation wereall quite near, but very different from those of the native cobalt ores. (4) For the Ming blue-and-white ware, the MnO/CoO and Fe_2O_3/CoO ratios were withinthe range of 0.81~6.08 and 0.41~5.81 respectively. The ratios of the five specimens invest-igated were extremely divergent. It is very likely that in the Hsuan Te period, cobalt oreswith low MnO and high Fe_2O_3 content were used; but in the Cheng Hua period, amixtureofnative cobalt ore and cobalt ore with low MnO and high Fe_2O_3 content were used ins-tead; while in the Cheng Te and Chia Chin period, a refined and calcined native cobalt orewas selected. (5) For the three samples of the Chin blue-and-white ware examined, their MnO/CoOand Fe_2O_3/CoO ratios lie within a narrow range of 5~7 and 0.4~1 respectively. It is likelythat the blue pigments used in this period were derived from the refined and calcinedcobalt ores produced in Chekiang province. In these studies, underglaze blue pigment painted on the Tung Kuan ware (铜官窑) andChun ware (邛窑) were also investigated. It was found that the coloring element was cop-per oxide, while that of the blue pigment painted on the three-colour-glazed T'ang warewas cobalt oxide.

本工作收集了历代制作的青花瓷器的若干典型样品,并对它们的化学组成、显微结构、气孔率和烧成温度作了检测。 为了了解用于中国古代青花瓷器的各钴矿的不同来源,并加以比较,尚测定了若干典型国产钴矿的化学组成。 从各化学分析的结果发现: (1)国产钴矿含有高百分比的MnO和低百分比的钴。这种类型的钴矿是通常所谓的“钴土矿”。 (2)画在北宋浙江省发掘的青花瓷器上的青花色料的MnO/CoO比和Fe_2O_3/CoO比分别为10.25和0.61。这些值与国产钴矿的值十分接近,看来用于该时期的青花色料是国产钴土矿。 (3)元朝青花的MnO/CoO和Fe_2O_3/CoO比分别为0.01~0.06和 2.21~3.02。所有研究的五个样品的比值均十分接近,但与国产钴矿差别很大。 (4)明朝青花的MnO/CoO和Fe_2O_3/CoO比分别在0.81~6.08和0.41~5.81的范围内,所研究的五个样品的比值是非常分散的,很可能宜德青花是用含低锰高铁的钴矿;成化青花是用国产钴矿和低锰高铁钴矿的混合物;而正德和嘉靖青花是选用了精选和煅烧过的钴土矿。 (5)清朝青花的三个样品的MnO/CoO和Fe_2O_3/CoO比经测定出来处于...

The microstructures of the antique Jun(Chun)ware sherds of Henan province were stu-died by means of OM、EM、SEM、DTEM and ED method. Some properties such as porosityand bulk density were also determined. Two of the samples were analysed chemically. Theresults have proved that: 1.The glaze of antique Jun (Chun) ware of Henan province has four major structuralcharacteristics: (1)the cristobalite recrystallizes as horse tooth shape crystallites aroundthe remnant granules; (2)a layer of anorthite or plagioclase is formed between the bodyand glaze by chemical reaction;(3)there is the separation of micro-pore phase; (4)bothred speck area and blue glaze area have two liquid phase separations; and that as networkmodifier copper and iron ions are rich in the isolated phases. The experimental evidencesof DTEM proves to clarify the mechanism of the coloring of copper and the opalescent effectin the glaze. 2.Experiments on the heating behavior of the glaze and the observations of the micro-structures of body and glaze proved that the firing temperature of Jun (Chun) ware glazemust be above 1250℃ or even higher up to above 1300℃. 3.The undetermined spots with diameter of ? 1.5μm in the red speck area also impartto the effect light scattering.

用OM、EM、SEM、DTEM、ED等技术研究了河南省的均窑古瓷残片的显微结构。测定其气孔率等性质并且对一些试样进行了化学分析。结果证明: 1.河南古均窑釉具有四大结构特征,即1)方英石在残留颗粒周围的马齿状析晶;2)特有的胎-釉反应生成的钙长石或斜长石反应层;3)微泡气相的分离;4)红斑区和兰色釉区两者都存在着的二液相分离。铜、铁离子作为网络修饰子富含于孤立相之中。DTEM的实验证据可以阐明釉中铜着色和产生乳光的机理。 2.釉的受热行为的试验以及胎的显微结构观测证实古均窑的釉烧温度应在125℃以上,高者甚至可达1300℃以上。 3.红斑区中直径为≤1.5μm的未定性颗粒也起着光散射的作用。
