Trivia

• Stone or Cobblestone can be mined by hand, but it will not yield the resource after being broken.
  • It takes about 4 seconds to do so, much longer in duration than with the correct Tool.
  • Flint and Steel or Shears can be used to break Stone relatively faster than by hand.
• The Player can make a Cobblestone Generator with Water and Lava, making it an infinite resource to obtain Cobblestone in the Overworld.
  • This is not possible in The Nether, as Water cannot be placed there, and will evaporate instantly.
• When the colors of the Cobblestone texture are inverted, it appears to be End Stone.
• Since Ghast Fireballs cannot blow up Cobblestone, it can also be used as protection against the former in the Nether.
• Cobblestone naturally generates in Dungeons and Jungle Temples along with Moss Stone.
• Before Update 0.12.1, Cobblestone was used to build a Player-built structure known as the Nether Reactor.
