The 硬化沙块 is a type of 物块, along with 沙岩块s, that make up the 地下沙漠 生物群落. It looks similar to 沙块s, with an altered texture and slightly different color. Unlike sand, it is not affected by gravity. Like all sand-based blocks, it has 腐化, 猩红, and 神圣 counterparts: Hardened Ebonsand, Hardened Crimsand, and Hardened Pearlsand respectively.
- In 困难模式, Hardened Sand Block is a "corruptible" block, and can be converted to its corrupted version of Hardened Ebonsand, Hardened Crimsand, and Hardened Pearlsand, and spread the corruted biome to nearby corruptible blocks.
- Even though Hardened Sand can be crafted into 玻璃, its biome-specific counterparts cannot.
- Unlike other items used in crafting recipes, a Hardened Sand Block's tooltip does not contain the Material tag.
