So over the years I've heard that smelting high end ore should be done in smaller batches. Does anyone know if the success rate for smelting really matters on the size of the ore pile? Also, what different does extra mining make? Is it 'worth it' to get a pair of +5 mining gloves (I have +3s now), both for mining itself (will I get more colored ore per vein) and for smelting? Thanks.
