Blocks



The environments of Terraria are mostly made up of blocks such as dirt and stone.

As of 1.2, All blocks can be collected with a Pickaxe. Rare blocks may require higher-grade Tools to mine.

The only blocks that can't be mined with a Pickaxe are any blocks with a Tree, Chest or Demon Altar on top, which need to be harvested using an Axe for the tree, or Pickaxe for the Chest and Demon Altar first.

Bricks
Bricks are a sub-type of placeable blocks that can be used to build a house or to craft background walls. Pink, blue and green bricks cannot be crafted and are mined from the Dungeon instead. Lihzahrd Bricks can only be mined from the Jungle temple with a Picksaw. Bricks can be recovered with a pickaxe once placed.

Mechanisms
Mechanisms were introduced in version 1.1 and can be found in caves and tunnel systems throughout the world.
