A preliminary study on several Jun ware sherds was completed in september 1981.Fourtypes of characteristic structure existing in Jun glaze were confirmed, with convincingevideaces of liquid phase separation structures in the glaze. Based on these results, eleventypical Jun sherds of the Song and Yuan Dynasties were collected and investigated. The chemical compositions of the eleven samples, both of the glaze and body weregiven.The glaze and body formulas in different periods of the Song and Yuan Dynastieswere compared respectively. The optical properties and element constituents of the interlayer between the glaze andthe body were studied by optical microscopy (OM) and energy dispersion X-ray spectrometer(EDX) respectively which brings the conclusive results that the interlayer is ananorthite crystalline layer produced due to the reaction between the glaze and the body.For all the specimens, liquid phase separation structures were observed generally by DTEMand a systematic measurement of liquid droplet size distribution was carried out.The globaldroplets and the r<λ (~500A) conform to the critical condition for Rayleigh scattering. Abrief explanation to opalescent mechanism of Jun glaze was given in accordance with Ray-leigh theory. Cubic crystallites of cuprite (Cu_2O) were discovered to be existing in red Jun glaze ofthe specimens which were thinned by ion bombardment as observed with DTEM and ana-lysed with EDX.Hence an inference can be drawn from these results that the red liquidphase droplets contain Cu~+ ion, which causes coloration by selective absorbing and scat-tering of incident light waves. The greyish blue particles in the red region were found and investigated by STEM,EDX and ED and proved to be small polycrystalline particles of chalcocite (Cu_2S), whichcontrols the coloration of Jun glaze from violet to red as a result of different proportions ofparticles and droplets. The mechanism of coloration of Jun ware is thus solved and the door to further inves-tigation of coloring mechanism of copper red glaze is now opened. Finally, three possible sources of sulfur are discussed briefly. We conclude that sulfurcontaining copper ore may be one of the raw materials used in the manufacturing of thered Jun glaze in the Song and Yuan Dynasties.

Changsha Tongguan Kiln was a famous folk kiln of Tang Dynasty. In this kiln area the brown, green and red colored glazed wares and underglazed painted wares were produced in the ancient time. The Tongguan ware bodies are similar to Zhejiang celadon bodies and Jingdezhen porcelain bodies in chemical composition. High silica and low alumina contents are characteristics of these bodies. The Tongguan ware glaze mainly contains a great amount of CaO as flux, but MgO and K(Na)_2O contents are less than 3%. Otherwise the glazes containing P_2O_5 are also high. All these showed that some wood ashes might be used as the raw materials for making glazes in the ancient time. The variety of colored glaze or underglaze are closely relating to the firing atmosphere and concentration and valence of copper or iron ions in the glazes. A certain amount of SnO_2 exists in the green or red glazes or colors, which might play a role of reduction reagent. The firing temperatures of Tongguan wares are in the range of 1150——1200℃. The brownish red underglaze might be formed by mixing decoration of copper and iron ions as the coloring reagents.

长沙铜官窑是唐代的名窑,该窑烧制褐色、绿色和红色的色釉瓷和釉下彩瓷器,铜官窑瓷的胎在化学组成上相似于浙江青瓷和景德镇瓷器,如高SiO_2含量为南方瓷胎的特征。铜官窑釉主要含大量CaO作为熔剂,而MgO和K (Na)_2O的含量则低于3%,另一方面釉中P_2O_5也很高,这些都表明古代一定使用植物灰作为制釉原料。色釉和釉下彩颜色的变化与烧成气氛和铜、铁离子在釉中的浓度有密切的关系。绿色和红色釉的彩中均含有一定量的SnO_2,可能起还原剂的怍用。铜官窑色釉和釉下彩瓷的烧成约在1150°-1200℃的温度之间。褐红色的釉下彩是由铜和铁两种离子混合作为着色剂而肜形的色调。

The jadeite was synthesized from jadeite glass made at 1350-1550℃. By adding certain amounts of Cr+3,Cu+2 and Co+3 cations, jadeite with emerald green, redand blue colours has been obtained respectively. The effects of pressure and temperatureon the synthesis of jadeite are also discussed.
