The effects of interfacial heat transfer on thermocapillary convection in liquid bridges of high Pr fluids placed in ground-based experiments are described in this chapter. Heat exchange due to convective and radiative heat transfer along the liquid bridge surface can sensitively affect the thermocapillary convection. Section 2 shows the effects of heating/cooling of the liquid bridge on the instability responsible for the transition from steady to oscillatory state of convection, while Sect. 3 focuses on the suppression and control of convection through the local surface heating of the liquid bridge. Section 4 deals with a full zone liquid bridge heated with a ring heater, where the thermocapillary convection which is driven by the thermal radiation from the ring heater can be controlled by the minimum heating power given by the second ring heater. The interfacial heat transfer also becomes important in microgravity as described in Sect.  6 of Chapter “Microgravity Experiments in Kibo Onboard the International Space Station.”
