A multi-domained bulk REBa.sub.2 Cu.sub.3 O.sub.x with low-angle domain boundaries which resembles a quasi-single domained material and a method for producing the same comprising arranging multiple seeds, which can be small single crystals, single domained melt-textured REBa.sub.2 Cu.sub.3 O.sub.x pieces, textured substrates comprised of grains with low misorientation angles, or thick film REBa.sub.2 Cu.sub.3 O.sub.x deposited on such textured substrate, such seeds being tailored for various REBa.sub.2 Cu.sub.3 O.sub.x compounds, in specific pattern and relative seed orientations on a superconductor precursor material which may be placed in contact with a porous substrate so as to reduce the amount of liquid phase in the melt. Because seeds can be arranged in virtually any pattern, high quality REBa.sub.2 Cu.sub.3 O.sub.x elements of virtually unlimited size and complex geometry can be fabricated.
