Fire is a non-solid block which produces 15 units of light. It has animated faces on all four sides, and two more faces on the inside in an X shape. Fire blocks are only generated naturally in The Nether and in The End (on top of the bedrock that spawns on top of the pillars). The Player can create fire using a flint and steel or a fire charge. Ghasts and Blazes can also create fire, as can lava and lightning. Fire spreads naturally to other nearby flammable blocks, and it can be placed as a block in modded clients.
