Caption: New techniques, like thermographic scans, are used to investigate the materials used in the construction of historic structures. Image: Image from a historic structure report, showing a thermographic scan of a building. Caption reads “Figure S-46. Composite thermograph of the south elevation west of the existing center door, showing thermal anomalies consistent with a double header, suggesting an infilled opening. Note the thermal differences between the clay-set pierrotage and the fill used between logs below the header, suggesting these are different materials.”
