Abstract: The bluish white porcelain of Luochong kiln was first made in Five Dynasties and it was the representative of the bluish white porcelain during the early stage of Fanchang kiln. X-ray fluorescence spectrometer (EDXRF) was used to analyze the body and glaze of Luochong porcelain. And contrastive research was also made systematically with the white porcelain of Ding kiln, Jingdezhen kiln and Qingshan kiln in the Late Tang Dynasty and the Five Dynasties. Investigation and analysis conducted on the basis of polarized light microscope observations, whiteness value, water absorptivity and firing temperature indicate a strong similarity between Luochong kiln and Ding kiln. Also, the whiteness value of porcelain from Luochong kiln porcelain can be as high as that of white porcelain. And the body of the sample has a dense structure, indicating that it had reached a high fire temperature at that time.

Key words: Luochong kiln, bluish white porcelain, chemical composition, microstructure, energy dispersive X-ray fluorescence (EDXRF)
