[origin: GB2248569A] A casting including an interior cavity defined by a frangible core (101) wherein the casting is cast around the core (101) which is subsequently broken, preferably shattered, to leave the so-defined interior cavity within the casting. In the preferred embodiment, which is directed to a furnace tuyere, the shattered core is flushed from the casting using a high pressure fluid. The core may be shattered using an explosively-generated shock wave which, also in the preferred embodiment, is provided by an explosive threaded through at least part of the hollow core prior to detonation. <IMAGE>
