Silt Blocks are soils that are very similar to Sand Blocks that start appearing from the cavern layer. It is affected by gravity and will deal damage to any player or mob they fall on. Unlike sand, It can stop the Hallow, the Crimson, and the Corruption from spreading. It looks similar to Ash Blocks, but is a lighter color.
Silt can be placed on an Extractinator to spawn various valuable materials, including gems, coins, ores, and very rarely, the Amber Mosquito pet summoning item.
- When the Wall of Flesh is defeated for the first time, and the "Spirits of Light and Darkness" are unleashed, Silt Blocks inside the new Corruption, Crimson, and Hallow biomes will be converted to Ebonsand/Crimsand and Pearlsand respectively, much like regular sand. After this initial conversion however, Silt Blocks are not affected by the spread of Corruption and Hallow.
- Just like Slush and any form of sand It dissapears when it falls on a rail track.
- Silt can be used in the same way as Sand to fill lava pits. It can also be used in creating traps, since it causes damage to whatever it falls onto.
