From: Glass beads from a Scythian grave on the island of Khortytsia (Zaporizhzhia, Ukraine): insights into bead making through 3D imaging

Fig. 9

Details from photogrammetry and CT scans for the bead KH8. A Direction of the rotation of the mandrel during bead formation and decoration. The starting point and ending point for the bead formation are indicated. B Elongated bubbles marking the direction of the rotation of the mandrel during the bead making, C Axial CT slice highlighting the layers of different glass. D Shape of the bubbles obtained by segmenting the CT volume. Several examples of “head and tail” bubbles are highlighted. E 3D model resulting from the combination of photogrammetric and micro-CT data. The detail of the junction of the ring decoration is also shown, F distribution of high-density inclusions (except the ring decoration) demonstrating the winding pattern
