Sandstone Blocks are found naturally-placed in the 地下沙漠 生物群落. Sandstone 物块 don't affect whether an area qualifies as an Underground Desert biome. The only qualification for such a biome is a naturally generated sandstone wall. Like 沙 and Hardened Sand it has 腐化, 猩红, and 神圣 counterparts: Ebonsandstone, Crimsandstone, and Pearlsandstone respectively.
- Even though sandstone will not create an Underground Desert biome, its biome-specific counterparts will create and spread their respective biomes.
- Oddly enough, it can't be used to make 沙岩砖 and 沙岩板, despite the similarity in names.
