Composition and microstructure of Yuan Dynasty Jun glazed stoneware from Yanjialiang site, Inner Mongolia, China

This is the authors' abstract. We don't add key points for this paper.

This study aims to investigate the production techniques and kiln origins of the unearthed Jun-glazed wares. It examines the microstructure and chemical composition of the wares, as well as their physical properties. The investigation employs a combination of ultra-depth field microscope, SEM-EDS, EDXRF, ICP-MS, TIMS, and thermal dilatometer. The analysis revealed that the content of Al 2 O 3 in the body of Jun glaze ware unearthed from the Yanjialiang site is high, with YJ9 reaching 39.72%. It exhibits distinct formula characteristics in its body material and relatively coarse production quality, markedly differing from the Jun-glazed wares of the Song, Jin, and Yuan Dynasties excavated in Henan, China, in terms of composition, microstructure, and other aspects. This is the first time that this unique Jun-glazed wares composition has been discovered. Some Jun-glazed wares were produced from the Ding kiln, Hebei Province, others are likely produced from Jun Kilns in central and western Henan, as suggested by their compositional data.
