The microstructures of Ge(ko) type and celadon type sherds,which were excavated fromthe great capital of Yuan dynasty were studied by means of polarizing microscopy, electronmicroscopy and scanning electron microscopy. The results assured that the glazes of Ge typesherds are of crystalline nature with long prismatic plagioclase crystallines. These glazes havean opalescent appearance and crackled mainly because of the plagioclase crystallization.The Ge type and celadon type glazes are almost the same in chemical composition, onlythat the CaO content in celadon type glazes is higher. However, from results of physicalchemical analysis it can be shown that the compositions of these two glazes are withindifferent primary crystalline regions in CaO-Al_2O_3-SiO_2 phase diagram. The microstructureof celadon glazes has the properties of glass nature and an appearance belonging to a pe-culiar style. It has found that there are many scattering particles between the plagioclasecrystallines in the Ge type glazes.The experimental results prove that these particles aresubmicroscopic pores with diameters less than 2000A. By examining in detail the micro-structures of the porcelain bodies of the excavated sherds, the different raw materialsfrom which they were made have been identified.

用偏光、超视显微术和电子、扫描电子显微术研究了元大都出土的哥窑型和青瓷残片的显微结构。结果证实哥窑型釉是一种析出钙斜长石柱状雏晶的结晶釉。钙长石的析晶是哥窑型釉产生乳浊性和釉裂的主要原因。该出土的青瓷釉与哥窑型釉在化学成分上相似,其CaO含量甚至更高。但物理化学分析研究表明,两者所处的CaO-Al_2O_3-SiO_2参考相图中的初晶区截然不同,青瓷的显微结构基本上保持玻璃釉的性质而在外观上另具一格。发现哥窑型釉中析出的钙长石晶体之间有散射微粒,实验证明,它是一种尺寸<2000A的亚显微空泡或气泡。详细研究了出土残片的瓷胎的显微结构,说明了它们所用原料的异同。

By X -- ray diffraction analysis, transmission electron microscopy and scanning electron microscpy, the paper gives the description of the mineral phase change in porcelain body composed of Xinzi Kaolin and Nangang china stone under the temperatures from 700 to 1320℃ in an electric kiln. The result shows that under the heating temperatures from 700 to 1000℃ kaolinite in porcelain body will produce mullite crystalltes Under the heating temperatures about 1000℃ sericite in porcelain body begins to form mullite and γ--Al_2o_3 but not leucite, and at the same time it is discovered that even under temperature of 1300℃ sericites still remains pseudomorph of serici te in the original shape, which shows that sericite does not melt but its chains have been broken and partly decomosed to mullite.

本文通过X光衍射分析、透射电镜与扫描电镜的观察,研究了星子高岭—南港瓷石坯料在电炉中从700℃至1320℃的物相变化。研究结果表明瓷坯中的高岭石加热至700℃~1000℃范围内出现了莫来石雏晶,瓷坯中的绢云母加热至1000℃左右时,开始形成莫来石与r—Al_2O_3,而未生成白榴石。同时发现即使在1300℃的温度下绢云母仍保留着片状形态的假象,这说明绢云母并没有熔融,但己断链,并部分转变为莫来石。因此过去认为此瓷相中存在绢云母,实为绢云母假象。

To explore systematically the characteristics of Ding white porcelain, some typicalfragment samples of its kind were taken from the ancient kiln sites, and their outerappearances,chemical compositions, microstructures and some ceramic physical proper-ties were respectively examined. Furthermore, to know the technological features of theDing white porcelain, main clay minerals near the kiln sites were collected;they under-went chemical and differential thermal analyses and a series of comparative experimentwith the present imitations as well. The results indicate: 1)Of the early dynasties,the quality of Ding white porcelain is at its poorest andthe surface of the body is glazed fyith a decorating clay as engobe; from the Late TangDynasty to Jin Dynasty,the quality of Northern Song wares is the best. 2)The Ding white porcelain bodies from the late Tang to Jin Dynasty generally havea high content of Al_2O_3,that is about 31~35%.Meanwhile,they contain a relatively greatamount of mullite and a rather low amount of cristobalite.In addition to the fact thatthe porosity of Jin white ware body is much higher, the other bodies of Ding white porce-lain have a porocity range of about 0.5~1.5%, thereby resulting in high density andhigh bending strength. 3)As compared with the white glazes of Jindezhen and Dehua white porcelain,theDing white glaze has a higher content of MgO and a lower content of CaO. Therefore, itcan be said that the Ding white glaze belongs to CaO-MgO-Al_2O_3-SiO_2 system, whichmight be called the "Magnesia-lime glaze". 4)From the results of spectro-reflectivity of the glaze and the transmittancy of the bodi-es, it might be proved that the reducing firing technique was being used in late Tang andFive Dynasties, and the oxidizing firing technique was being used in Northern Song andJin Dynasty. 5)Local mineral resources are in abundance.The great part of c1ay minerals,be-longing to the secondary sedimentary kaolin,contains a great deal of quartz,feldspar,calcite,talc, dolomite etc.Thus,it can be deduced that the ancient Ding white porce-lain was made mainly from the local materials.

为了系统地探讨定窑白瓷的特性,将历代具有代表性的实物残片样品,分别进行了外观鉴定、化学分析、显微结构及物理性能测定。为了进一步了解其工艺特点,并对当地主要粘土进行了化学分析和差热分析,同时又与现代生产的定窑白瓷进行了对比试验。 研究结果表明:(1)早期白瓷质量最差,并施有化妆土;唐后期至金,以北宋最佳,其他次之。(2)唐后期至金的瓷胎中 Al_2O_3含量均较高,在31~35%之间;胎内还含有较多的莫来石和少量的方石英,胎的气孔率除金代较高外,其他均在0.5~1.5%之间,故致密度高,抗折强度大。(3)定白瓷釉与景德镇、德化白瓷釉相比,釉中MgO含量较高,CaO含量较低,属于MgO-CaO-Al_2O_3-SiO_2系统,可称“镁-灰釉”。(4)从釉的分光反射率和胎的透光度曲线,证明唐、五代瓷器为还原焰烧成,北宋和金的瓷器为氧化焰烧成。(5)当地粘土属于沉积高岭,蕴藏丰富,并有白云石、石英、长石、石灰石等,推知古代制瓷主要就地取材。
