Currently TC smeltery cannot deal with BR recipes, yellorite/graphite ingots etc... Is this possible to add?

I'll have to take a look at TC's API; I imagine it won't be impossible. That said, not sure if this'll make 0.3.

Melting highly radioactive material in a smeltery designed for metals not seems to be a valid idea.

Nice compat, but not feels valid

How about a different request: Is it possible to get Manyullyn added as a valid coil material?

I've split out the Manyullyn suggestion into a separate issue, #253.

Hmm, I'm actually going to close this. Adding TiCon compatibility requires me to peg the amount of liquid in an ingot at 144mB, which isn't where I want it for 0.6. Sorry.
