Redstone Ore is an ore in Minecraft. It is usually found 16 levels or below above Bedrock, although it can be found in other places, and is fairly common there. When mined, which takes an Iron Pickaxe or higher to drop anything, it will drop 1-4 Redstone Dust (without the Fortune enchantment; Fortune III can yield up to 32 Redstone). This makes Redstone very easy to gather, so long as one avoids death.
How to obtain
Mine with an Iron Pickaxe or higher enchanted with Silk Touch to obtain the ore, not the item, Redstone.
Redstone is often found in close proximity to lava, so exercise caution when mining.
Redstone Ore is also found in very long caves that are deep. It even can be found in ravines too.
When left-clicked or walked on, Redstone Ore will make a faint light which can be quite useful in dark Caves when you have run out of torches.
