Imitation of ancient black-glazed Jian bowls (Yohen Tenmoku): Fabrication and characterization

Yohen Tenmoku is a kind of famous black glazed Jian bowls made in ancient China. Here, imitations of Oil Spot Yohen Tenmoku were sintered at about 1280 °C in a shuttle kiln with oxygen flow. Microstructure characteristics and chemical compositions were investigated by a combination of X-ray based and photon based characterization methods. The results showed that quartz and mullite were the main crystalline phases in the bowl bodies. At the glaze surface of the bowl, the highly reflective red iridescence and the silvery appearance of Oil Spot patterns were resulted from the precipitation of hematite (α-Fe₂O₃) crystals. A detailed study has revealed the partially ordered microstructure within one Oil Spot which produced the striking optical effects.

植物纤维餐具碗在运输包装环境抗冲击行为有限元分析

为分析运输环境中可降解餐具碗在发泡聚苯乙烯缓冲下的冲击性能,并为此类产品的破坏模式给予评估,利用ABAQUS/Explicit建立碗与发泡聚苯乙烯在跌落冲击下的有限元模型。引入失效准则及单元删除研究餐具碗破损规律,分析跌落速度对碗的影响规律,并与无缓冲包装碗的跌落进行对比。分析碗叠合在缓冲泡沫作用下的冲击响应。结果表明,泡沫缓冲对冲击结果影响较大,可有效避免碗的破损。     

Studies on the microstructure of the black-glazed bowl sherds excavated from the Jian kiln site of ancient China

The Jian kiln, located in present-day Jianyang county of Fujian province, mainly produced black-glazed tea bowls. Jian tea bowl was used as a utensil for tea tasting and was greatly appreciated by emperor Huizong of the Northern Song dynasty. The black glaze of Jian bowl was sometimes marked with streaks or spots, usually called “hare's fur” or “oil spot”, which are the crystalline markings of iron oxide precipitated during firing in the dragon kiln. In this study, black-glazed Jian bowl sherds excavated from the late Northern Song strata of Luhuaping and Daluhoumen Jian kiln sites were adopted as test samples. Based on the physico-chemical foundation for the formation of glaze microstructure, the correlation among composition, microstructure, and visual appearance has been investigated by means of energy-dispersive X-ray fluorescence, X-ray diffraction, and field emission electron microscopy. For the first time, the study provides realizing proofs for two kinds of microstructural forming mechanics.
