It's straightforward to "cast" it, harder to get a reliable pour in
such a long thin section as this.
Ahh, I see.

It also depends on your brass alloy. It's easier if you have something
that can be taken to a higher temperature (without dezincing) and
remains fluid to a lower temperature.
Longer working time essentially, contact with the mould cools it to a
point where it's no longer free flowing or even solid, could you not
pre-heat the mould or even work up a spin casting system I wonder?

Personal preference would be to make the walls thicker
Tin bronzes will generally be an
easier route to this than zinc brasses.


Frog-feet cast in silver, but missing out the usual intermediate
moulding steps. Burn-out is a bit stinky...
Nice, think I'll pass on that one.
