Abstract Thermocapillary convection (TC) has been studied experimentally in a NaNO3-melt of some cm3 volume. TC has been identified, its streamlines and flow velocities have been visualized and measured. TC dominated over natural convection in this ground based experiment and will be a very significant flow phenomenon in the relevant μ-g materials science experiments with melts with free surfaces. The sensitivity of TC to surface perturbations is pointed out. TC is very difficult to control.
