Forge

Forge is a spell from Ars Magica 2. It coverts raw blocks into their smelted form and villagers into Emeralds. If the block's smelted form happens to be an item, such as Iron Ore to Iron Ingot, then the block will disappear and drop its item. If it happens to be a block, such as Sand to Glass, then Forge will replace the raw block with its smelted counterpart - This applies to Ice and MineFactory Reloaded's Unmelting Ice as well.

Forge can be found in the Occulus's Offence tab, and requires a green Skill Point to be unlocked.
