  • provenance research by inaa on ancient Chinese white Porcelain excavated from the maojiawan site of beijing
    Journal of Archaeological Science, 2013
    Co-Authors: Guoxi Xie, Songlin Feng, Xiangqian Feng, Lingtong Yan, Jihao Zhu, Hongye Han
    Abstract:

    More than one million shards of ancient Chinese Porcelain were excavated at the Maojiawan pit in Beijing in September 2005. Among these shards, four types of ancient Chinese white Porcelain were identified. The ages and provenances of three of these types of Porcelain were accurately determined by archaeologists based on typology. However, different archaeologists interpreted the other/fourth type differently. According to the colour of the Porcelain body, it was easily identified as the product of the Jingdezhen kilns of the Ming dynasty (1368-1644 AD). However, based on the vessel shape, this fourth type of Porcelain was also identified as the product of the Cizhou kilns of the Yuan dynasty (1271-1368 AD). In order to determine the provenance of this type of ancient Chinese white Porcelain, 131 shards comprising the four types of white Porcelain identified at the site were selected as experimental specimens and analysed by Instrumental Neutron Activation Analysis (INAA). After the processing of experimental data by principal component analysis and geochemical analysis, the results show that the provenance of this type of ancient Chinese white Porcelain is the Jingdezhen, not the Cizhou kiln.

  • Chemical composition and provenance of Chinese Porcelain shards recovered from Old Goa, west coast of India
    Journal of Archaeological Science: Reports, 2017
    Co-Authors: Sila Tripati, G. Parthiban, J.n. Pattan, Andrew Menezes
    Abstract:

    Abstract During recent archaeological explorations at Old Goa, west coast of India, twenty three Chinese Porcelain shards of the Ming (Middle to late 16th century), Qing (17th century) and late Qing period (late 17th century) have been recovered. In order to understand the nature and source of raw material and kilns, these shards were analysed for major elements with X-ray fluorescence (XRF), trace and rare earth elements by Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). The analysis suggests that Porcelain shards are siliceous in nature (SiO 2  ~ 70%) and contain high Al 2 O 3 (21.6%), Rb (388 ppm) and Ba (160 ppm) but have low Sr (48 ppm). This composition suggests that the raw materials used for producing Porcelain were silica, kaolinite and sericite which are characteristics of Porcelains manufactured in Southern China. Comparatively, high Al 2 O 3 (kaolinite) content in Porcelains of the Qing Dynasty suggest improvement of quality, particularly mechanical strength, of Jingdezhen Porcelain. In general, major element composition, trace metals, total rare earth elements (∑ REE-67 ppm) and their chondrite - normalized pattern of the Ming, Qing and late Qing period are nearly similar and appear to be made of identical raw materials.

  • Illustration of compositional variations over time of Chinese Porcelain glazes combining micro-X-ray Fluorescence spectrometry, multivariate data analysis and Seger formulas
    Spectrochimica Acta Part B: Atomic Spectroscopy, 2014
    Co-Authors: J. Van Pevenage, Debbie Lauwers, Davy Herremans, E. Verhaeven, Bart Vekemans, W. De Clercq, Laszlo Vincze, Luc Moens, Peter Vandenabeele
    Abstract:

    Abstract In this research, the transparent glaze layers of Chinese Porcelain samples were investigated. Depending on the production period, these samples can be divided into two groups: the samples of group A dating from the Kangxi period (1661–1722), and the samples of group B produced under emperor Qianlong (1735–1795). Due to the specific sample preparation method and the small spot size of the X-ray beam, investigation of the transparent glaze layers is enabled. Despite the many existing research papers about glaze investigations of ceramics and/or Porcelain ware, this research reveals new insights into the glaze composition and structure of Chinese Porcelain samples. In this paper it is demonstrated, using micro-X-ray Fluorescence (μ-XRF) spectrometry, multivariate data analysis and statistical analysis (Hotelling's T-Square test) that the transparent glaze layers of the samples of groups A and B are significantly different (95% confidence level). Calculation of the Seger formulas, enabled classification of the glazes. Combining all the information, the difference in composition of the Chinese Porcelain glazes of the Kangxi period and the Qianlong period can be demonstrated.

  • A combined spectroscopic study on Chinese Porcelain containing ruan-cai colours
    Anal. Methods, 2014
    Co-Authors: J. Van Pevenage, Debbie Lauwers, Davy Herremans, E. Verhaeven, Bart Vekemans, W. De Clercq, Laszlo Vincze, Luc Moens, Peter Vandenabeele
    Abstract:

    Because of its major contributions to the world economy and cultural heritage, Chinese Porcelain and its technology can be considered as very important. In this research, the applicability of Raman spectroscopy and X-Ray Fluorescence (XRF) spectroscopy to study the pigments of the ruan-cai colour palette of Chinese Porcelain dating from the 18th century was evaluated. Next to the investigations based on stylistic analysis, the use of other analysis techniques is important to obtain complementary information. Raman spectroscopy and XRF spectroscopy are two non-invasive, analytical techniques proven to be useful for the determination of the nature and composition of pigments used to decorate ceramics. As a result, analytical analysis allows us to retrieve more information about the production of Chinese Porcelain. Based on visual inspection of the decoration, the objects could be divided into two groups and to evaluate the use of the combined analytical approach, all groups and subgroups were sampled. Before Raman and XRF analyses, the samples were cut, embedded and polished, in order to be able to measure the transversal section of the samples. In this way, each layer of the Porcelain samples could be analysed separately. The results show that the blue colour is cobalt-aluminium oxide, in red zones haematite (α-Fe2O3) is present and the green area contains a mixture of CuO in a lead-rich basis and a solid solution of malachite (Cu2CO3(OH)2). The opaque yellow and white colours were identified as lead tin yellow type II (PbSn1−xSixO3, where x ∼ 0.25) and a lead arsenate, respectively.
