In this data article, we present the spectroscopic structural data of the pottery samples collected from Petén Itzá, Guatemala. Detailed Fourier transmission infrared, powder X-ray diffraction, scanning electron microscopy coupled to electron dispersive X-ray diffraction, and thermal gravimetric analysis/differential thermal gravimetric analysis (FTIR, PXRD, SEM/EDX, and TGA/DTGA) were discussed in the research article titled "Comprehensive Structural and Compositional Investigation of Maya Pottery Sherds from Lake Petén Itzá, Guatemala, Central America" (Onchoke et al. 2020 [1]) The FTIR, XRD profiles and composition of pottery from Petén Itzá, Guatemala are presented. This data is important and useful for further understanding of the structural composition of pottery sherds used by Maya people of Guatemala. In addition, the TGA/DTGA profiles provide information on the content of the losses upon heating and offers supportive evidence to the spectroscopic data studied.
在本数据文章中，我们展示了从危地马拉佩滕伊察采集的陶器样本的光谱结构数据。在题为《中美洲危地马拉佩滕伊察湖玛雅陶片的综合结构与成分研究》（翁乔克等人，2020年[1]）的研究文章中讨论了详细的傅里叶透射红外光谱、粉末X射线衍射、扫描电子显微镜与电子色散X射线衍射联用以及热重分析/差示热重分析（傅里叶变换红外光谱、粉末X射线衍射、扫描电子显微镜/能谱分析和热重分析/差示热重分析）。展示了危地马拉佩滕伊察陶器的傅里叶变换红外光谱、X射线衍射图谱和成分。这些数据对于进一步了解危地马拉玛雅人使用的陶片的结构组成非常重要且有用。此外，热重分析/差示热重分析图谱提供了加热时损失量的信息，并为所研究的光谱数据提供了支持证据。
