We propose viscosity measurements of molten oxides using Aerodynamic Levitation (ADL) with CO2-laser heating which can achieve container-less and non-contact conditions for measurements. For viscosity measurements, we used a unique vibration method that causes oscillations in a sample and levitates a gas via acoustic speakers. Using these techniques, we clarified the surface oscillation excitation mechanism and then, based on this understanding, we measured the viscosity of molten Al3O3 and its temperature dependence.
