Netherrack

"Netherrack was added to the Java edition of Minecraft in Alpha version 1.2.0, the Halloween Update, alongside pumpkins, clocks, fishing and the Nether. Spoiler alert: the Nether is where netherrack gets its name from (though it was originally called “bloodstone”, eww), and it’s also where you’ll find more netherrack than any one person could ever need."

- Duncan Geere
