= 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.  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.
