The change of volume, shape, generated bubbles and crystal structure from glass state in room temperature to fused state in high temperature, which was difficult on ground surface, were successfully observed by floating experiment for fused glass under microgravity environment. The expected results for temperature-volume relation of glass such as rapid volume increase at from 400 to 500 C near glass transition temperature were obtained by image processing of a boarded VTR tape. However, phenomena unexpected in ground surface experiment caused such as generation of big bubbles or crystal growth at 600 C or higher. Further detailed investigations on this cause would result obtaining important information for production and fabrication of glass in future under space environment.
