In this research, one precious sherd unearthed from Linshui (one major site Under-glaze black decoration of Cizhou kiln system) in Hebei province was adopted as specimen for compositional and micro-structural Microscopy analysis analysis. Optical microscope (OM), X-ray fluorescence spectrometry (XRF) and energy dispersive spectrometry (EDS) in association with scanning electron microscope (SEM) were employed for investigation of the multi- colour decors and black outline. The extensive data reveal that although high lead content has been detected by surface analysis and the iron-rich pigment particles do locate in the middle of the whole vitrified region, the black outline in fact belongs to high temperature fired under-glaze painted decoration, rather than the deceptive low temperature fired lead based over-glaze decor or the generally believed ‘sandwich’ (glazed twice) structure. Furthermore, a corresponding criterion then has been established for differentiation among three main decorating methods, especially for the puzzling ‘sandwich’ effect scenario. Moreover, once this ongoing vexed debate over the nature of the black decoration in Cizhou kiln system has been clarified, it is then reasonable to deduce that, from idealistic and technical point of view, there is no difference between producing prototype like this sherd and real Doucai in Ming dynasty (1365–1644 AD) except for the types of under-glaze pigment. Overall, all these results together firstly provide realising scientific proofs for the origin of Doucai. 1. Introduction Due to its unique artistic design and distinguished status, the origin and development of Doucai attract lots of attention in ancient ceramic DouCai is exquisite polychrome porcelain which boomed in researches.

Ceramics International 43 (2017) 1371–1377 of the largest scale and highest level porcelain manufacturing centre in northern China, starting ceramic producing in late Tang (618–907 AD) dynasty and continued up to the early Ming dynasty. Unlike dogmatic and inflexible governing in official kiln, many breakthroughs regarding shaping, decorating methodology and thermal power revolution have been made by humble but wise artisans and impacted the later emerge of Jizhou and Jingdezhen kilns fundamentally. Only few Honglvcai sherds with black outline have been excavated archeologically. For this paper, one precious Honglvcai sherd (archae- ological code: 02LSH13), provided by Fengfeng District Conservation Institute of Cultural Relics and Archaeology, had been unearthed from the strata of Jin Dynasty at Sangong site, Linshui in 2002, and further Fig. 1.

The photograph of the sample is presented in Fig. 3 with front and back views, where the body is sort of yellowish grey and the applied famous for black under-glaze decoration.

The sherd is probably techniques had been observed in Dongshan kiln, located in Changzhi, part of the sculpture or porcelain pillow; both are representative Shanxi province but belongs to Cizhou kiln system during Jin Dynasty. artefacts of Cizhou polychrome objects.

The first survey was More importantly, it is reported that for the black decoration on carried out non-destructively by energy dispersive XRF (Horiba XGT- black and white porcelain, the black pigment particles locate in the 7000, Japan). The instrument was performed at 30 kV and 0.062 mA in middle of glaze under SEM observation [3–6].

The interest piece was then coated with a thin explanation that the pigments would be pushed up by the crystal carbon deposit for systemic SEM (Zeiss MA EVO 25, Germany) growth and bubbles produced during firing. However, Meng [8] backscattered electron (BSE) mode observation and semi-quantitative challenged such perspective in terms
