Claim 8:
9. The method according to claim 1, wherein the melt receiving space (4) is designed such that when it is at least partially filled with melt (2), it is closed off in a gas-tight manner, wherein a gas valve (7) is formed, by means of which gas can be fed into or removed from the melt receiving space (4), wherein the gas valve (7) is opened while the melt container (3) is being filled with melt (2), so that the melt (2) can flow out of the crucible (25) and into the melt receiving space (4) via the lance (20), and the gas valve (7) is closed after the melt (2) has flown in, and subsequently, while the gas valve (7) is closed, melt (2) is discharged from the melt receiving space (4) back into the crucible (25) via the lance (20) until a vacuum is generated that is sufficient to keep the remaining melt (2) in the melt receiving space (4).
