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?

Things still do cool in shaded space, though, it just takes longer. The James Webb took like a month or two to get down to cryogenic IIRC.

I have a feeling OP was worried about gravity, which isn't usually helpful here, but isn't actually a dealbreaker. Glass is heavy too.
