Glass melting test in an accoustic levitation furnace has been carried out in the microgravity environment of 0.1-0.001G and lasted about 20sec. Composition of the glass was 65CaO·25Ga2O3·10GeO2 (in mol%). Sample was prepared so as to be convenient for observing a sequence of melting and glassifing behavior at high temperature in the microgravity. The heat source of the accoustic furnace was 1, 000W halogen lamp. The sample was confirmed to be a sphere owing to the surface tension at molten state and to levitation in the furnace by accoustic potential for the duration of microgravity.
