Soils

Soils are the mineral-based blocks in the game. By using a Pickaxe to hit the ground, the soil itself will turn into a block. All soils can be stacked up to 250, which makes them some of the easiest items to store.

Most of the soil that the player will get will be from digging into the ground. Digging long tunnels will greatly increase the character's supply of soils.

Type	Description
Dirt	The most accessible soil on any map. It has some interesting properties in that grass, Corruption and Hallow will spread across it.
Stone	The second most accessible soil. While dirt is easier to obtain, stone is much more plentiful further underground. It is a bit more durable than dirt, and is considered a “safe” material to build houses with.
Sand	Yellow terrain most commonly found in deserts. Sand cannot hang in the air like other blocks, and will fall to whatever surface is below it. Falling sand will damage players and NPCs, so be very careful when mining it. It is this property that makes it great for PvP. Sand can be crafted into Glass at a Furnace.
Clay	Clay deposits can be found underground, most commonly just below the surface in the Underground. Clay is currently used in crafting only. Clay will not grow vegetation.
Mud	Mud is found in the Underground, as well as Surface and, most commonly in the Underground Jungles. It is used to grow Glowing Mushrooms. The mushrooms can only be grown at a depth of 0ft or below. Mud covered in Jungle Grass can grow Moonglow, whereas bare mud can grow Blinkroot instead. If mud gets near Corruption in hardmode, it will turn into dirt.
Ash	This is found in The Underworld alongside Hellstone. Fireblossom seeds can be planted in this soil.
Silt	Functions the same as Sand, and will fall when mined, dealing damage to the player if they are underneath when it collapses. While it serves no crafting function, unlike sand it is immune to Corruption and Hallow.
