Ductility evaluation of high Tc Bi-Pb-Sr-Ca-Cu-O is quantitativelty perfomed with a Vichers' indentation method. The liquid-quenched (L.Q.) glassy oxide which doesn't show the superconductivity above 4.2K is brittle. On the other hand, the high Tc crystal oxides are ductile. It is especially that the sintered sample before L.Q. shows ductility more higher than the crystallized sample after L.Q.
