“…Pink lines refer to ferrihydrite ◂ intense the reduction atmosphere is likley to be established. Accordingly, The analyzed potteries in this study showed the Fe(II)/Fe(II) values between 0.06 and 0.11, which is significantly lower than those of celadon glaze (2.5 -7) fired at a reducing atmosphere [17]. Although the area ratio of Fe(II)/Fe(III) and chromaticity did not show any distinct relationship between the two, it might have been affected by the texture of the surfaces or particle sizes.…”

It is assumed that clay soil with high Fe contents as its main ingredient was used in the red pigment layers on the surfaces of the Neolithic Age Red Painted pottery and the Red Burnished pottery in the Bronze Age that were excavated from the southern areas of the Korean peninsula. A variety of phases of iron oxides that form pigment layers were identified through X-ray diffraction analysis, Raman spectroscopy and Mössbauer spectroscopy in this study. In particular, although previous studies focused only on hematite as a pigment mineral, the Mössbauer spectra of pigment layers in this study showed a higher spectrum area ratio of sextet by ferrihydrite than that by hematite, implying that ferrihydrite in reddish-brown might have played a significant role in developing its color. In addition, as it can be seen in each specimen showing a different area ratio by site in the Mössbauer spectrum, compositions of Fe-containing minerals were different. It is assumed to have been caused by different ionic forms of iron in the soil materials and unstable firing atmosphere during Pit firing.

“…Glaze Colorations can be classified into three types using the Fe form (Hwang, 2008), i.e., ionic colorations (as in the celadon glaze), colloid colorations (as in the tenmoku glaze), and crystal colorations (as in the iron crystal glaze). Scientific analysis of the iron oxide phases during the coloring of a celadon glaze and iron glaze has been conducted using a Mössbauer spectrometer (Hwang, 2008;Jeon et al, 2011;Kim et al, 2010;Pyon, 2005). Raman spectroscopy analysis has also been carried out on Cheolwha Buncheong ware and blackware (Lim, 2013;Park, 2018).…”

A Preliminary Study on the Roles of Fe Content and Neoformed Ca-rich Minerals in the Coloration of Ceramic Glazes

Iron oxides are the essential coloring oxides in traditional ceramic glazes. However, when Fe is involved in the coloration in the form of ions or colloids in glazes with low Fe content, it is difficult to identify the iron oxide phases. Generally, in many these glazes, Ca-rich minerals are observed by X-ray diffraction (XRD) or microscopic images, owing to their devitrification by the high Ca content. This study attempts to elucidate the correlation between the crystalline structure and coloration in the glazes while mainly focusing on neoformed Ca-rich minerals and Fe content. An experimental firing was carried out to produce tree ash glazes, with pine tree ash and Buyeo feldspar. In the case of oxidation glazes, the scanning electron microscopy (SEM) images and XRD patterns did not exhibit any Ca-rich crystals, and all the visible light reflectance spectra lines exhibited a similar shape. In contrast, the reduction glazes divided into blue glazes and other colored glazes according to the shapes of their reflectance spectra. It was confirmed that the influence of Ca-rich minerals on the glaze color was more pronounced than the blue color of the reduction glazes when the Ca and feldspar contents were sufficiently high and low, respectively, to form wollastonite. As the Ca content increased and the elemental composition of the reduction glazes changed, the neoformation of the Ca-rich minerals, such as wollastonite, anorthite, diopside, and akermanite was sequentially observed.
