Platinum blocks are decorative mineral blocks made from Platinum Ingots which do not appear in normally generated maps anywhere. Platinum blocks have the same texture on all six sides.
Platinum blocks can be made by placing 9 Platinum Ingot in a 3x3 square on a Crafting Table. The 9 ingots can be recovered by placing the block in a crafting grid. This makes iron blocks more functional as storage units than as building units.
Platinum blocks can be mined with a stone, iron, or diamond Pickaxe, taking about 2 seconds to destroy. If a platinum block is mined without the use of a pickaxe, it drops nothing, wasting all 9 ingots.
