Images of ceramics were acquired in two different ways. The first-seen in Figure ,b,d,c and Figures S6-8-were acquired by placing ceramics flat or tilted on top of a high resolution Edmund Optics (1951 USAF) 33 inch fused silica test target with vacuum deposited chromium patterns with illumination from under the sample with white light source. These images were acquired with a Nikon COOLPIX 5700 digital camera. Images through perovskite ceramics (see the TOC graphic and Figure ,f) were acquired using an iPhone 13 Pro with ceramics held a ~1 centimeter from the camera lens. The FLIR image in Figure was acquired using a Teledyne FLIR A6750 camera (f/2.5, pixel size 15x15 μm, spectral range 1.0-5.0 μm) with a Teledyne FLIR 50 mm f/2.5 lens (1-5 μm BBAR coating) using FLIR's ResearchIR software.
