Yeah and make sure you refine your ore through the ore processor first, as that allows more orichalcum to appear and may provide other additional materials.
I just sort of threwn that reaction together, that's why it says replace a reaction your not using... and pewter are some of the reactions I never use. The additions to inorganic were required to make it take any titanium bearing rock. The rest of the reaction is oil from any soap material, flux and fuel...
But anyways I targeted the metallurgist in it because it seemed right... i could have targeted the crucible or any of a number of buldings... personally it doesn't matter to me, but I think it would be off if the bower shop made titanium.
