Similar to Ice Blocks, Thin Ice has reduced friction, and players will slide across it. Thin Ice will break if a player falls on it at a certain speed, usually achieved by falling normally onto it. Landing on Thin Ice will not cause fall damage itself, but it will not slow the player's fall on contact, and fall damage will continue to accumulate until the player lands on another block type (unlike Cobwebs, for instance, which reset fall damage). Ice Skates or any of the combined accessories that use them as an ingredient can be used to land on Thin Ice without breaking it and dropping through (also potentially taking fall damage, however).
Thin Ice is destroyed permanently when crashed through or broken with a pickaxe, drill or explosive, dropping nothing. On the 主機版、 前代主機版、和 , blocks of Thin Ice cannot be picked up, crafted or moved in any way. 版
- 薄冰僅能由上方開始破裂，所以試圖水平或從底部衝過薄冰是不可能的。Using a grappling hook to attach to a Thin Ice block from above will break through the block, but grappling from any other side is safe.
- The use of a Gravitation Potion will not break the underside of the ice block. Using a gravitation potion and falling towards the top of the block will result in it breaking. This leads to the conclusion that Thin Ice blocks can only be broken from the top side.
