Archaeometric characterization of 17th-century tin-glazed Anabaptist (Hutterite) faience artefacts from North-East-Hungary

Abstract

13The paper presents the first results of a long-term project aiming to reconstruct the production 14 technology of the Anabaptist (Hutterite) tin-glazed ceramics produced in Eastern-Central analytical data on the direct or indirect precursor, Italian maiolica. 18The studied Hutterite faience artefacts reveal similarities with the Italian maiolica.

Archaeometric study of 17th/18th century painted pottery from the Belgrade Fortress

“…Principal component analysis (PCA) and the scattering matrix based dimension reduction were applied as unsupervised and supervised pattern recognition technique, respectively, to explore the grouping and classification of the pottery samples [44,45]. The aim of the PCA analysis was to extract the parameters carrying the majority of variability, which may consequently structure the initial dataset into m; this finding is in agreement with results obtained for 17 th century faience artefacts found in Hungary [22]. Optical micrographs of cross sections of all investigated pottery samples are given in Table S1 (in Supplementary Material).…”

“…Gehlenite forms from the decomposition products of illite and calcite at 800-850 o C [50,51], while diopside is obtained from illite, calcite and quartz at 850-900 o C [52]. The presence of these phases in the BF III samples ( [22] show similar mineralogical compostion to group BF III. This result is particularly important in the wider context, due to the constancy of some manufacturing sequences, especially the strategy of procurement of raw materials and firing procedures in all chronological stages of production of Haban faience.…”

“…There are reports on the pottery craft, techniques and technological features derived from written documents [1,19], and experimental archaeometric studies have also been initiated. So far, painted pottery analyses from only a small number of excavation sites have been reported, such as the studies of Malhornware from Upper Austria [20] and Anabaptist or Haban faience from south Moravia [21] and Hungary [22].…”

Breaking Preconceptions: Thin Section Petrography For Ceramic Glaze Microstructures

“…Blue decorations. These decorations applied on Renaissance and Modern glazed ceramics, often contain Pb-Ca arsenates crystallites that are formed by the reaction between the arsenic and the other glaze components [33,[39][40][41][42][43][44][45][46][47]. The use of thin sections in transmitted plane polarized light (TL-PPL) allows us, on the one hand, to achieve a fast overview on the application procedure of the blue decoration and, on the other, to immediately spot the crystallites (Figure 1a-c).…”

“…In fact, they are normally described in literature as euhedral, rounded, angular, or tabular crystallites with hexagonal sections [40,41,47]. In some cases, acicular morphologies have been observed using SEM, when the crystallites are trapped into degassing bubbles [42,46,47]. In other words, for such thin acicular crystals, the probability to have a longitudinal section on the polished surface is extremely low and only basal or subbasal sections will be visible.…”
