Unfortunately, in the current state of Calcite in Minecraft, as of the latest 1.17 snapshot, not much can be done with the block. However, another block added to the game is always a good thing, as it means builders have a more diverse arsenal to create epic things with.
Although it’s a shame there isn’t really much practical use for Calcite, players who would like to pick the block up must make sure to break it with a pickaxe. This is because Calcite has the same properties as stone, such that it will not drop anything if broken with anything but a pickaxe.
1.17 is, of course, not officially released at the time this article was written. Therefore, it’s entirely possible that Mojang may decide to add some unique uses for Calcite.
