Can molten metals in space get shaped like glass on Earth?

What might prevent metal "blowing" and other forms of shaping from working if gravity was not a factor? Let's handwave-ignore the extremes of temperature as it relates to techniques and the present primitive space habitats and craft.

Is it possible to suspend a pool of molten metal, with a tube inside, spin while adding a gas to shape a container, and form more complex shapes through additional heat cycles in a repeatable process?
