[TheForge] Silicon bronze

[Mike Mastrangelo]

Not certain that this will work for you, but when there are voids in
lost-wax bronze castings, we generally fill the voids using a TIG welder
and silicone bronze rods. I have been able to build up the bronze to a
point where you can grind/sand/and polish it to the original surface
