“…However, the use of different raw materials in the same region was not expected until the chemical compositions were identified with pXRF. Additionally, the detection of trace elements reveals the importance of more precise measurements, since the literature only shows the results of major elements, such as Fe, Ti, Ca, and K [54,55], which cannot distinguish provenance differences. In addition to Dutch productions, Wedgwood artefacts reflect a change in the content of the body, which may reflect a transition from old (earlier-19th century) to recent (later-19th century) productions by diminishing the amount of potassium.…”

“…With this study, the chemical characteristics of European (nine unglazed objects produced in England, France, Russia, and Holland) and Chinese (one enameled and 10 unglazed objects) red stonewares were defined by using an on-site characterization technique, pXRF, which allowed a methodology to be created for distinguishing the differences depending on the provenance and authenticity of the artefacts. The recent analyses were compared with the previously studied [35] 25 unglazed, polished, and non-polished objects, assigned to have been made by Böttger at Meissen, in addition to the reference materials published in the literature [54,55]. Technological differences, which depend on the provenance of the artefacts, were revealed as a result of this study.…”

“…A limited number of studies about the characterization of Böttger red stoneware have been published since the 1990s [9,35,36,[49][50][51][52][53][54][55], particularly about the Delft and other European productions. With this study, the chemical characteristics of European (nine unglazed objects produced in England, France, Russia, and Holland) and Chinese (one enameled and 10 unglazed objects) red stonewares were defined by using an on-site characterization technique, pXRF, which allowed a methodology to be created for distinguishing the differences depending on the provenance and authenticity of the artefacts.…”

The invention of European hard porcelain, which aims at imitating kaolin-containing white paste of Chinese porcelain, had been started by the development of the technology of “red porcelain”, so-called “Jaspisporzellan” by Johann Friedrich Böttger in the early-eighteenth century at Meissen (Saxony). The visual features of the earlier Böttger red stoneware were rather similar to the one produced in Yixing, China. The prominence of Böttger productions allowed the manufacturing to be expanded across Europe to different countries (Holland, England, France, etc.). In this study, the chemical characteristics of nine European unglazed objects produced in England, France, Russia, and Holland from the 17th to 19th century and 10 Chinese (unglazed or enameled) red stoneware have been studied by using an on-site characterization technique pXRF. The results were compared with the previous studies carried out on 25 unglazed, polished, and non-polished Böttger artefacts. This non-invasive, speedy technique allows a methodology to be created for distinguishing the technological differences related to the provenance and authenticity of the artefacts. The elemental measurements explicitly show the significant discrepancy of Dutch objects from the main group, which involves other European and Chinese ones. Both a Lambertus van Eenhoorn (Delft) statue and an Ary de Milde (Delft) teapot are distinguishable from other European red stoneware by the high content of iron and calcium and high content of titanium and potassium, respectively, found in their body compositions. An overall comparison was made between the measurements made at different times in order to evaluate the error range arising from the measurement procedure (e.g., energy resolution of other series of the same instrument model).
