Abstract
An apparatus includes a frame and a crucible having a central axis and a bottom. The crucible is supported and is moved so that the central axis of the crucible describes a substantially conical surface with an apex located substantially on the central axis and spaced from the bottom of the crucible by a distance equal to or less than the crucible height. The crucible is restrained against rotation about its own axis.
