Extremely dense glasses in the Bi Sr Ca Cu O system have been made by splat quenching. Single superconducting transitions at 110 K have been observed in crystallized samples from both resistivity and magnetization shielding experiments. Magnetization J c has been found to increase greatly at high field (H= 5T) as copper and calcium rich precipitates are introduced into the system.
