Study on the Influence of Calcination Temperature of Iron Vitriol on the Coloration of Ancient Chinese Traditional Iron Red Overglaze Color.

Iron red, a traditional Jingdezhen overglaze color, is primarily colored with iron oxide (FeO). In traditional processes, the main ingredient for the iron red overglaze color, raw iron red, is produced by calcining iron vitriol (FeSO·7HO). Analysis of ancient iron red porcelain samples indicates that the coloration is unstable, ranging from bright red to dark red and occasionally to black.

Processing, Microstructure, and Performance of Robocast Clay-Based Ceramics Incorporating Hollow Alumina Microspheres.

The restoration of ancient ceramics has attracted widespread attention as it can reveal the overall appearance of ancient ceramics as well as the original information and artistic charm of cultural relics. However, traditional manual restoration is constrained due to its time-consuming nature and susceptibility to damaging ancient ceramics. Herein, a three-dimensional (3D) printing technique was employed to accurately restore Chinese Yuan Dynasty Longquan celadon using hollow AlO microsphere-modified 3D printing paste.

Three-Dimensional Microstructure of ε-FeO Crystals in Ancient Chinese Sauce Glaze Porcelain Revealed by Focused Ion Beam Scanning Electron Microscopy.

Ancient Chinese sauce glaze porcelain has recently received growing attention for the discovery of epsilon iron oxide (ε-FeO) crystals in glaze. In this work, we first confirm the presence of ε-FeO microcrystals, in large quantiteis, in sauce glaze porcelain fired at the Qilizhen kiln in Jiangxi province during the Southern Song dynasty. We then employed focused ion beam scanning electron microscopy (FIB-SEM) to investigate the three-dimensional microstructure of ε-FeO microcrystals, which revealed three well-separated layers (labeled, respectively, as LY1, LY2, and LY3 from the glaze surface to inside) under the glaze surface.

[Raman and EDXRF Study on Overglaze Decorations of Jingdezhen Ceramics].

Overglaze decoration porcelain is an important category of ancient Chinese ceramics, which has significant artistic value and scientific value. Nondestructive analysis methods such as Raman spectroscopy and EDXRF were used to analyze the overglaze decorations on the Jingdezhen ceramic samples of Yuan, Ming and Qing Dynasty. The recipe and color mechanism of the overglaze pigments were discussed according to the chemical composition and phase composition analysis.

[Chemical composition and chromaticity characteristic of purple-gold glaze of Jingdezhen imperial kiln].

Color glaze is one of the four famous traditional ceramics of Jingdezhen, especially for the products from Ming and Qing Dynasties' official kilns which have rich connotation of technology and culture. The chemical composition and chromaticity characteristic of glaze and body of purple-gold glaze samples from Jingdezhen Ming and Qing Dynasties' official kilns were analyzed by energy dispersive X ray fluorescence (EDXRF) and colorimeter. Preliminary study on the composition, formula and chromaticity characteristic of glaze of purple-gold glaze samples of different period was carried out and the intrinsic causes of ifferences were discussed.

[Research on the composition characteristics of imitated Longquan celadon in Jingdezhen and Longquan celadon].

Longquan celadon not only has been loved widely by the domestic and international ceramic lovers, but also imitated by the kiln workers from different places. Among all of the imitated celadons, the most representative products appeared in Ming and Qing dynasties. This paper used EDXRF to test 38 pieces of Longquan celadon of Song, Yuan and Ming dynasty and imitated Longquan celadon in Jingdezhen of Ming dynasty, combined with firing temperature in order to analyze the different composition characteristics of the bodies and the glaze, evolution rule and formation reasons of these samples in the two different places from the views of time and space.

[Chemical composition and chromaticity characteristic of Jilan glaze of Ming and Qing official kilns].

Color glazes of Ming and Qing official kilns are excellent representatives of the famous ancient Chinese porcelains. The study of official ware with Jilan glaze has been an important topic. But it made slow progress due to the rarity of samples with strict production management and using system.

[Research on the composition characteristics of Chinese ancient southern white porcelain].

The southern white porcelain is the rise in our country's pottery, it is later than the development of northern white porcelain, but it is rising stars, blockbuster, well-grounded, keeping continuous. Jingdezhen kiln and Dehua kiln are the most representative kilns among the southern white porcelain kilns. the present paper used EDXRF to test 30 pieces of Song, Yuan and Ming period' Dehua white porcelains and Jingdezhen Yuan dynasty Shufu white porcelains samples to analyze the different characteristics of the bodies and the glaze of these samples in terms of time and space.

[EDXRF study on the chemical composition and raw material recipe of Jindezhen porcelains in the five dynasties].

Early crafts of porcelain making in Jindezhen were an important issue in ceramic history of China. The chemical composition of white porcelain and celadon samples excavated from Xianghu Kiln in the five dynasties was analyzed using energy dispersive X-ray fluorescence (EDXRF). Raw material recipes of the samples were discussed.
