Clay

This dense building material has the potential to be molded into sturdy walls, elegant pottery, or exquisite statues. You'll probably use it to make a gun, though. What does that say about your priorities?

Clay is very common making it easy to identify early on. Clay is used in many starting recipes (along with Dirt, Mud, & Rock). As with dirt it will also be useful through the entire game.

Appearance
