Simple geometric considerations show that to maximize the transport Jc for a given type of bulk superconductor, it is only necessary to have the individual grains in the sample oriented with maximal area of close contact with their immediate neighbors. With this guideline, a 24-meter silver-sheathed thallium-containing superconductor of the 1223-type without long-range granular alignment has been made. It is flexible, uniform, and exhibits a transport Jc of 104 A/cm2 at 77 K in the absence of external magnetic field.
