Silt Blocks are soils that are very similar to 沙块s that start appearing from the 洞穴 地层. It is affected by gravity and will deal damage to any player or mob they fall on. Unlike sand, It can stop 神圣之地, 猩红之地, and 腐化之地 from spreading. It looks similar to 灰烬块s, but is a lighter color.
Silt can be placed on an 提炼机 to spawn various valuable materials, including 宝石, 钱币, 矿石s, and very rarely, the 蚊子琥珀 宠物 summoning item.
- 首次血肉墙被打败之时，即所谓"光明与黑暗之魂"被释放出来时,被划为新形成的腐化、猩红和神圣生物群系中的泥沙块会被分别转换成黑檀沙或猩红沙还有珍珠沙，就像普通的沙子。After this initial conversion however, Silt Blocks are not affected by the spread of Corruption and Hallow.
- Just like 雪泥 and other forms of sand, it disappears when it falls on a rail track.
- Silt can be used in the same way as 沙 to fill lava pits. It can also be used in creating traps, since it causes damage to whatever it falls onto.
1.2：Stack limit increased from 250 to 999. Also can now be used in Stucco blocks and turned into "something more useful" via the 提炼机.
