我们以前报道过陶瓷的太赫兹（THz）波透射率随烧成温度变化很大。在这项研究中，我们提出了一种新的方法来准确地估计从考古遗址出土的古陶瓷碎片的烧制温度的基础上，这种依赖性。利用太赫兹时域光谱技术（THz-TDS）测量了古有田瓷器和Banko陶器碎片的太赫兹波透射特性。从制造时使用的原材料或目前可用的原材料制备标准样品，并测量其THz波透射特性作为烧制温度的函数的校准曲线。根据校准曲线估算出的古代有田和Banko碎片的烧成温度分别为1241 ± 3 °C和1141 ± 1 °C。这些温度在由X射线衍射分析估计的烧制温度范围内。由于我们提出的估计方法是基于一个校准曲线，一个较窄的着火温度估计范围获得。我们认为我们的新方法太赫兹波分析是一个更准确的方法来估计古陶瓷的烧制温度。
We previously reported that the terahertz (THz) wave transmission of ceramics varies strongly with firing temperature. In this study, we propose a new method to accurately estimate the firing temperatures of ancient ceramic shards excavated from archaeological sites based on this dependency. THz time-domain spectroscopy (THz-TDS) was used to measure the THz wave transmission properties of ancient Arita porcelain and Banko pottery shards. Standard specimens were prepared from the raw materials used at the time of manufacture or currently available raw materials, and calibration curves of their THz wave transmission properties as a function of firing temperature were measured. The firing temperatures of the ancient Arita and Banko shards estimated from their calibration curves were 1241 ± 3 °C and 1141 ± 1 °C, respectively. These temperatures were within the firing temperature range estimated from X-ray diffraction analysis. Because the estimation method that we propose is based on a calibration curve, a narrower firing temperature estimation range is obtained. We consider our new approach to THz wave analysis to be a more accurate method for estimating the firing temperatures of ancient ceramics.
