Stone Block

Stone Blocks are a type of block that composes most of the world. Found mostly underground, they compose the majority of the Cavern and Underground layers. Deep underground, Stone Blocks can generate with Moss growing on them.

As a crafting ingredient, Stone Blocks are vital early in the game to craft the Furnace and Wooden Arrows.

After hardmode is activated on a world, nearby corrupt, crimson and hallowed blocks can spread through Stone Blocks, changing them into Ebonstone, Crimstone, or Pearlstone, respectively. Ebonstone and Crimstone Blocks can be returned to normal with Purification Powder, whereas Pearlstone Blocks require Vile or Vicious Powders. All three types can also be purified with the Green Solution.
