This mod adds a new ore to Minecraft call the Ore Pieces Ore and basically this ore will drops pieces of iron, coal, diamond, and gold. But those pieces aren't ingots they are Pieces of the those ingots. So after getting some pieces of the ingots, you can put them in a crafting table and craft mini tools/weapons from them. Also by putting the pieces in a 2x2 crafting area, you will get an ingot, for example you have 4 diamond pieces, put them in a 2x2 crafting bench and you will get a diamond.
