Stonemill

Stonemill is about stone and earth. Its quern gives a steady supply of gravel, sand and clay without a portal duplication farm.

Quern

The quern works like a furnace. Rock goes in the top slot and fuel below it, and each grind burns as much fuel as smelting one item. Hard rock takes twice as long, so it burns twice the fuel. Grinds rock down into cobblestone, gravel, sand, clay and quartz, burning furnace fuel.

Two tanks on the left hold charges, up to 64 each:

• A water bucket adds 32 water charges and leaves an empty bucket behind.
• Orange dye adds 8 dye charges.

A tank only takes an item once all of its charges fit. Gravel needs water to become sand; with dye as well it becomes red sand, and goes back to plain sand once the dye runs out.
