“…Finally, the presence of a grain of pseudobrookite, without any epitaxial relationship with other phases in the lamella presented, is most likely due to the local presence of a titanium oxide grain playing the role of a precursor, such as anatase which was identified in the raw material (Hole ´et al, 2022) or rutile which would result from its prior transformation at high temperature (Shannon & Pask, 1965;Djuric et al, 2014).…”

“…Samples ZJ-07 and ZJ-08 were selected for this study on the basis of preliminary experiments using XRD and Raman spectroscopy highlighting that only those two from the ZJ series contain "-Fe 2 O 3 . Hematite and Fe-containing spinel [(Mg,Fe)Al 2 O 4 ] were also detected on the surface of ZJ-08 only (Hole ´et al, 2022).…”

“…In particular, samples ZJ-07 and ZJ-08 were removed from the kiln at the beginning of the cooling step at 1160 � C and after the kiln had cooled to room temperature, respectively. More details about the sample manufacturing and the firing conditions are presented elsewhere (Hole ´et al, 2022).…”

“…Sample ZJ-07, which was removed from the kiln at 1160 � C during cooling, contains already well developed dendrites exclusively composed of "-Fe 2 O 3 , without hematite or spinel (Hole ´et al, 2022). On the other hand, ZJ-08, which was removed later at the end of the cooling, contains hematite and spinel in addition to "-Fe 2 O 3 .…”

“…Several studies have been carried out on ancient samples and highlighted typical dendritic micro-and nanostructures (Dejoie et al, 2014;Wang et al, 2019Wang et al, , 2021Wen et al, 2019;Ren et al, 2022). This set of samples was shown to display comparable dendritic structures, which contain two iron oxide polymorphs among other phases: "-Fe 2 O 3 and hematite (�-Fe 2 O 3 ) (Hole ´et al, 2022).…”

Black-to-brown Chinese ceramics have sparked the interest of material scientists since the widespread discovery of complex dendritic structures containing mainly the rare ɛ-Fe2O3 polymorph in their glazes. This study proposes to tackle this issue using two electron diffraction mapping techniques, transmission Kikuchi diffraction and automated crystal orientation mapping–precession electron diffraction, which have not been fully exploited despite their relevance for studying these structures at the scales of interest. It first demonstrates the efficiency of applying these techniques to characterize the structures at the nanoscale and discusses some limitations that may be encountered, in particular due to the specificity of heritage samples. It then focuses on the crystalline orientations obtained with these techniques, which highlight epitaxial relationships among the crystalline planes (001) of the ɛ-Fe2O3 phase, (0001) of the hematite and (111) of the spinel. Finally, it discusses the growth of such complex multi-phase structures by proposing two possible mechanisms, one based on the transformation of ɛ-Fe2O3 into hematite and spinel, and the other based on the growth of hematite and spinel on already crystallized ɛ-Fe2O3 dendrites. It also compares the dendritic structures of the two modern samples with those found in an ancient sample of Jian ware.

Sauce glazed wares of Yaozhou kilns are famous for their high gloss and distinctive glaze color palette varying from yellowish‐brown to reddish‐brown. In this work, sauce glazes were successfully replicated using the traditional technology of Yaozhou kilns. Micro‐Raman spectroscopy, combined with optical microscopy, scanning electron microscopy, x‐ray fluorescence, and reflective spectroscopy, was systematically applied to analyze the chemical composition, nature and distribution of crystals, and the coloration of the glazes. The results show that the yellowish‐brown glaze is mainly original from dendritic ε‐Fe2O3 crystals, whereas the reddish‐brown color is mainly derived from dendritic hematite crystals. Such dendritic structure could account for slightly color variations of the glaze surface observed in different angles, which also reported in Japanese Bizen ceramics. The principal component analysis (PCA) was further applied to study the Raman spectra of these iron oxides. The PCA results effectively indicates the structural disorders of these crystals introduced by ion substitutions. These substitutions could not only stabilize the crystals but also darken the crystals color. Besides, high Mg in the raw materials was found to benefit the growth of magnesioferrite crystals. The relative low level of Fe2O3, high level of SiO2, and CaO may relate to the formation of ε‐Fe2O3 crystals.
