Crushed Iron Ore is obtained by sieving sand with a 4:1 chance. It can then be crafted in a 2x2 pattern in any crafting interface to create an Iron Ore Sand block. An Iron Ore Sand block acts the same as a normal Iron Ore block, and can pulverised or be smelted into Iron Ingots directly. Iron Ore Sand can be broken with a hammer and broken down into Pulverised Iron therefore potentially ...
