Quern / Millstone ¶

The Quern or Millstone is a machine (can be automated or manual with a lever) that grinds-up material into fine powder or dust. This is useful for such things as turning bone into bonemeal, wheat into flour, or iron ore into red dust.

Craft the Quern ¶

First craft the quern using six stone blocks. The quern is not completed yet, it still needs a lever if you are going to operate it manually.

The Lever ¶

If you intend to operate the quern manually then craft a lever (from a stick and cobblestone) and place it on-top of the quern. Since the quern is a machine you will have to hold the Shift key (same key used for crouching) while you right-click with the lever to place it on the quern, otherwise if you right-click without holding shift then it will open the quern's GUI instead.

Using the Quern ¶

To use the quern you simply pull the lever as if you were flipping the lever / switch. You can only pull it once per second, this is slow and it is not a bug, it is a feature. Querns are very heavy and hard to operate due to the inertia involved, so it might be a good idea to build more than one quern and try to operate them concurrently. Also be aware that operating a quern consumes a lot of calories and makes you very hungry. Watch your hunger bar, as you operate the quern you will use up food shanks quite rapidly.

If you right-click the quern to bring-up the GUI you can check on the progress of your recipe:
