The mechanism of “flint red” and its relationship with celadon glaze color

"Flint red" is the red narrow band found in the exposed body of porcelain, which is a common phenomenon in ancient porcelain. Some experts believe that flint red is an important symbol for judging the age of ancient ceramics. This paper takes sky-green Yaozhou porcelain as the example, and successfully fired samples of Yaozhou porcelain with flint red, and reveals the formation mechanism of flint red. This study uses XRF (X-ray fluorescence), XRD (X-ray diffraction), SEM (Scanning electron microscope) and non-contact imaging spectrophotometer analysis to discover for the first time that during the reduction process, the iron of the glaze migrates to the body with the melt in the gas phase, and the flint red is a hematite thin film formed on the body after being oxidized for the second time during the cooling process of the kiln. The influence of the redox atmosphere and placement mode of ceramics on flint red were studied. The relationship between flint red and the degree of color reduction of celadon glaze surface was discussed. In addition, the growth method of hematite film is enlightening for the preparation of anticorrosive coatings on steel products, and has broad application prospects.     

Firing process and colouring mechanism of black glaze and brown glaze porcelains from the Yuan and Ming dynasties from the Qingliang Temple kiln in Baofeng,Henan, China

Black glaze and brown glaze porcelains were an important part of ancient Chinese iron-based high temperature glazes. The excavation of black glaze and brown glaze porcelains from the Yuan and Ming dynasties at the Qingliang Temple kiln site in Baofeng, Henan, China, in 2014, enriched the firing history of this kiln site and history of Chinese ceramics. In this study, black glaze and brown glaze porcelain samples from the Qingliang Temple kiln site from the Yuan and Ming dynasties were selected and analysed via optical microscopy, laser Raman spectroscopy, focused ion beam scanning electron microscopy combined with EDS and energy dispersive X-ray fluorescence to determine their microscopic morphology, microzone composition, microstructure and chemical composition. Moreover, the main wavelength range of the brown glaze porcelain samples were measured by UV–Vis–NIR spectrophotometer systems. The main conclusions of this study are as follows. The brown glaze porcelain from the Yuan and Ming dynasties at the Qingliang Temple kiln site has two different colour layers, with the surface is brown and the bottom is black. The presence of a glass phase and α-Fe₂O₃ phase in the black glaze porcelain samples, and a rare ε-Fe₂O₃ phase in the brown glaze porcelain samples. The brown colour was a result of ε-Fe₂O₃ precipitation, whilst the black base layer also enhanced the brown-colouring effect. Different glaze formulations were used for brown glazed porcelain, some of which were similar to those used for black glaze porcelain and derived from the transformation of black glaze porcelain through different firing atmospheres and cooling rates. Although the formula of the brown glaze porcelain samples exhibited differences, the main wavelength difference was not large, was within the 645–682 nm range and belonged to the visible red region.
