Redstone ore is a type of block found in the game Minecraft. It is typically located deep underground, usually between levels 1 and 15. When mined with an iron pickaxe or better, it drops redstone dust, which is used in various crafting recipes and to create complex mechanisms. When placed in the game, redstone ore emits a light level of 9, making it glow. It can also be activated by silk touch enchantments, allowing players to collect the block itself. This ore is essential for players interested in building contraptions and using redstone for automation.
