Infinite Lava Source
Infinite Lava sources were first added to the player's Inventory on January 22, 2010. Later they could be found in chests in the Indev House in a stack of 99 or 100. They were generated as a block in the world.
When placed, an Infinite Lava Source block creates 4 blocks of Lava at its sides which then spread infinitely like fluids in Minecraft Classic. Breaking the source block stops the spread.
