Microscopy, XRF and FTIR data from the project Medieval timber houses in Dalarna, project code RAÄ-2025-1685

Samples from medieval wooden doors in Dalarna, Sweden were sent by the County Administrative Board of Dalarna to the Heritage Laboratory at the Swedish National Heritage Board for analysis. The research question was to determine whether the doors are coated with tar or another substance. Data from the following analytical techniques is included: 1. X-ray fluorescence spectroscopy (XRF); 2. Fourier transform infrared spectroscopy (FTIR); 3. visible and UV light optical microscopy. Instrument reports are also included. Project code RAÄ-2025-1685. The analysis report compiling the data and the final report from the County Administrative Board of Dalarna can be found at: 10.5281/zenodo.18430769.瑞典达拉纳（Dalarna）地区的中世纪木门样本由达拉纳郡行政委员会送至瑞典国家遗产委员会遗产实验室开展分析。本次研究的核心目标为确定这些木门是否涂抹有柏油或其他涂层材料。本数据集涵盖以下三类分析技术所获数据：1. X射线荧光光谱法（X-ray fluorescence spectroscopy, XRF）；2. 傅里叶变换红外光谱法（Fourier transform infrared spectroscopy, FTIR）；3. 可见光与紫外光光学显微镜检测法。同时附带相关仪器检测报告。本项目编号为RAÄ-2025-1685。包含数据汇总分析报告及达拉纳郡行政委员会最终报告的资源链接为：10.5281/zenodo.18430769。
