Fig. 10

Details from photogrammetry and CT scans for the bead KH11. A Direction of the rotation of the mandrel during the bead formation. The starting point of the formation is marked. B Size distribution and shape of the bubbles in the reconstructed CT volume (colors of the bubbles depends on their size). C Axial CT slice highlighting a thin spiral of radiopaque material twisting outwards from the aperture. D Axial CT slice highlighting decorations (marked with blue ellipses), medium-Z inclusions (green) and oblate bubbles (orange). E High-Z material sunken in the base glass. F Details of the flattened area near the aperture, showing traces of a post treatment to refine the apex of the bead
