Evolution of the shape and gradual freezing of molten gold are shown. This is the run # 30 from Table 1 where the sizes are given. Green is solid gold, while red is liquid. Liquid is strongly overcooled below the melting point. Thus, nanocrystallites appear not only at the boundary of continuous solid with the liquid part but also inside the liquid part. The cross-section of the bump is presented. Thickness of this cross-section is 3 nm in direction normal to the plane of picture. The symmetry parameter shown by the green/red colors (defining the solid/liquid states) is obtained by averaging along this 3 nm. a t=216 ps, b 0.72 ns, c 1.37 ns, d 2.34 ns
