Abstract

Haltern 70 amphorae sherds from Castro do Vieito, a Roman settlement from the NW of Portugal occupied during the early imperial period, were studied by Mössbauer spectroscopy at room temperature and 4.2 K, XRD, and XRF, aiming to understand the firing conditions of their production. Firing in air at 750 and 800 °C were performed in a sherd that was carefully studied. Also, a handle with part of the neck attached and with the potter’s stamp “LH …” was studied. In general, it can be deduced that the amphorae were fired under reducing conditions between 800 and 950 °C, having been subjected to an oxidation process only when already cooling. It was also inferred that the provenance of all the Haltern 70 amphorae found in Castro do Vieito is probably the same and that the stamped amphora also seems to come from the same locality.

葡萄牙西北部 Castro do Vieito 出土的 Haltern 70 安福拉的莫斯鲍尔研究

通过室温和 4.2 K 下的莫斯鲍尔光谱、X 射线衍射和 X 射线荧光光谱研究了来自葡萄牙西北部罗马人定居点 Castro do Vieito 的 Haltern 70 个双耳瓶碎片，旨在了解其生产的烧制条件。在仔细研究后，对一个碎片进行了 750 ℃ 和 800 ℃ 的空气烧制。此外，还研究了一个带有部分颈部和陶器印记 "LH...... "的手柄。总的来说，可以推断出这些长颈瓶是在 800 至 950 ° C 的还原条件下烧制的，只有在冷却时才进行了氧化处理。此外，还可以推断出在 Castro do Vieito 发现的所有 Haltern 70 长颈瓶的产地可能是相同的，而且盖有印记的长颈瓶似乎也来自同一个地方。

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
