Melts of the target composition Bi2Sr2Ca2Cu3O10 were produced and quenched in a specially designed twin-roller device. Quenching rates were estimated to be between about 0.2-106K/s. In all quenching experiments mainly three sample shapes resulted, thin slivers, fibers, and clusters of sticking droplets. Slivers and fibres proved to be glassy, whereas the bulk of the clusters was crystalline.
