Ceramic fibers used as heat insulating materials for high-temperature furnace are produced in the blowing method that a high-speed jet blows molten ceramic dropping from a furnace. The insulation performance is improved with longer length of the fibers and with lower content of spherical shots that solidify without fiberization. These fiber properties are strongly affected by the shape of the jet nozzle though there does not exist the logical design method for it. Empirical methods are limited for its optimization, so that to detail information about the fiberization process is needed. In this study, visualization of the process using high shutter speed camera is attempted. The results show that fiberization process is completed before the fibers are blown only downstream of the nozzle diameter.
