Cobblestone
minecraft:cobblestoneCobblestone is a fundamental building material formed when flowing lava contacts water, with a hardness of 2 that requires a wooden pickaxe or better to mine. It underpins early-game crafting, forming stone tools, furnaces, brewing stands, pistons, and decorative variants like slabs, stairs, and walls. Because it forms wherever lava meets water, cobblestone is infinitely renewable through simple farm contraptions, and it also generates naturally in structures like mineshafts, villages, and strongholds.
