First off you can't "solder" cast iron......Cast Iron can be brazed or
welded......

Then I guess it can't be spackled either .....

Take the paret to a welder that can weld cast iron properly and it
should be able to be repaird...........however in the mean time, you
need to keep tyhe crack fropm propagating, so drill a small hole
about 3/32" diam at the exact end of the crack, it will relieve any
internal stresses and prevent the crack from going any further. You
can then apply some furnace cement into this hole and crack to seal it
up. This may last for years if you keep the crack from propagating,
but a weld would be the best proceedure to take in the long run.
