The crucible no longer accepts flux for the hematite and malachite templates. Flux can still be crafted as normal, and is usable in the Blast Furnace as always, but the crucible refuses to accept it, and if searched in NEI, only limestone is capable of generating flux foundry scraps (and works in practice as depicted). Not sure if a funny happened when adding limestone or if this is supposed to be a thing, so yeah, here ya go.

I'm running version 4543H1 just to be clear.

Just compiled the latest commit, seems good now. Thanks!
