A crystal growth experiment is carried out with a crystal placed on top of a glass rod. The rod is mounted on a Plexiglas platform. The chosen geometry permits better visualization of the convective plumes over the top face of the growing crystal. The parameters of growth during the experiment are as follows:  A small KDP crystal with bi-pyramidal morphology having its c-axis horizontal is glued to one end of a thin glass rod (1.5 mm diameter). The dimensions of the seed crystal are 2 × 1 × 2 mm³. The aqueous solution has a saturation temperature of 55.2^oC and the average cooling rate adopted during the growth is 0.02^oC/hr. The experiment is continued for 195 hours of which the initial 45 hours are required to reach the saturation temperature and heat the solution to avoid spurious nucleation. Crystal growth continues for 150 hours during which the solution is cooled by 3.5^oC. After about 60 hours of growth the crystal dimension increases and the plumes become strong. The plumes are seen to rise from the edges of the crystal. After about 100 hours of growth, plumes are seen to emerge from several spots on the top surface of the crystal. This indicates that there are several locations on the top surface where the accumulation of solution depleted of solute act as sources of plumes. At this stage the plume behavior becomes unsteady. Subsequently, the buoyant flow displays chaotic behavior as seen in the irregular plumes of the video.
