The Millstone is the smallest station in the game that unlocks a whole branch: flour for cooking, seed oil for the Distillation Cube, and minced meat from corpses. Two boards and two pieces of stone is the entire build cost.

Costs and research come straight from the game data, and “Where” is the work zone whose build desk offers the building — the game’s own placement record. “No research listed” means the page has none to show: either this build records none, or the game ships no name for it. In practice these rows are gated by materials, not by the tech tree.

Anyway...
“Inspiration lv” is the level this station’s own inspiration track has to reach — below it the recipe is not offered. “Needs” is the extension that has to stand next to the station before the recipe appears.

“Used here” counts how often the input appears in this page’s recipes and build costs; “no producing row” means the recipe, alchemy and crop tables all come up empty — you gather, hunt, buy or loot it instead.
Common questions
What does the millstone cost and what unlocks it?
2× Board + 2× Piece of stone, unlocked by the Millstone & Flour research (5 red / 10 green tech points). A conveyor variant, Kitchen: Millstone, costs 2× Polished Stone + 4× Stick + 2× Iron Detail.
What can the millstone make?
Flour from 4× Wheat (8 ticks), Seed oil from 4 seeds of any of seven crops (8 ticks, 2 oil each), and Minced Meat from 1× Flesh (3 ticks). Seed oil is the second route into Melted Fat at the Distillation Cube.
Is the millstone worth building early?
It is the gate to Flour and Seed oil, and both feed systems the game's main path touches (cooking and alchemy). If you already have Board and stone, the cost is trivial.
