Fig. 10From: Novel characterization techniques for cultural heritage using a TEM orientation imaging in combination with 3D precession diffraction tomography: a case study of green and white ancient Roman glass tesserae(From left to right) a FIB cutted thin slice of white tesserae containing several opacifier crystals selected for ADT diffraction tomography. b ASTAR phase mapping from three crystallites shown as 1–3; amorphous (black) areas can be readily distinguished from crystalline (magenta). c ASTAR orientation map where different colours correspond to different orientations shown in the stereographic triangleBack to article page
