I wanted to ask, if anybody know which focus can be assigned to which ore. I have already found out that the white focus is Aluminum Ore, brown = Bauxite and orange = Sphalerite Ore. Maybe someone else knows the remaining Focus ore types.
What Neonbeta said and keep in mind that not all ores match up with a color, or they share a focus with another ore. There is no documentation (except some old stuff on FTB's wiki), so trial and error is your only option.
Mostly the reason for limited documentation is because all ores minus the vanilla ores are added by MOredictrecipes, which was made by tonius.
I can Give Outdated info, but that won't really help. It's 1.4 info and its for the Other FTB packs. It may give the base on which ores match with the correct foci. http://ftbwiki.org/Laser_Drill And as Neon has stated, The Ores Minus vanilla is using an ore dictionary made by Tonius; Leaving all this info mostly irrevalant.
They were all changed by Tonius, I have no idea why you even bothered to post that. Also, he did not make the OreDictionary, he made a mod to add more stuff to it.
