摘要

双耳陶罐经常有一层白色的皮肤，这被误认为是在粉红色的陶瓷上涂了一层。这种表皮是由于粘土中同时存在方解石和NaCl，导致表面附近的红色氧化铁耗尽。我们证明了太赫兹飞行时间断层扫描可以提供一种非破坏性，非接触式的方法来测量双耳瓶碎片的皮肤厚度，发现厚度为~50 μm。

Terahertz Characterization of Roman Amphora Sherds

Amphorae frequently have a whitish skin that has been mistaken for a slip or painted layer over the otherwise pinkish ceramic. This skin is due to the simultaneous presence of calcite and NaCl in the clay, leading to depletion of red iron oxides near the surface. We demonstrate that terahertz time-of-flight tomography can provide a nondestructive, contactless means to measure the skin thickness on amphora sherds, finding a thickness of ~50 μm.
