Zusammenfassung:	The invention relates to the field of monocrystalline casting, and more specifically to a mold (1) for monocrystalline casting, and also to fabricating and using the mold. In particular, the mold (1) presents a mold cavity (7) comprising a first volume (7a), a second volume (7b) and a grain duct (4). The second volume (7b) is situated on the first volume (7a), being in communication therewith, and includes at least one horizontal projection relative to the first volume (7a). The grain duct (4) has a bottom end (4a) connected to the first volume (7a) and a top end (7b) adjacent to said horizontal projection of the second volume (7b). The mold (1) also has a separator member (11) interposed between the second volume (7b) of the mold cavity (7) and the top end (4b) of the grain duct (4).
