People keep asking about doubling ores, you can't in this pack without silk touch or late game machines. each smashed ore is one ingot until you get a QED or late game mekanism ore doubling (all well after you figure out how to make galgadorian metal) If you craft the smashed into an ore, you have to put it in a vat with lava before you can smeltery it for 2 igots (no point in doing that whatsoever) if you put a hardened ore in the ex-nihilo crucible you only get 1.5 ingots, so getting it by crafting the smashed ores is a waste, only useful if you are mining with silk touch, no use whatsoever with meteors.
