County of Fortune Second Glass Works – How to Build One

Build a second glass works by unlocking an extra building slot with equipment, then placing the glass works in that slot and supplying it with sand and potash. In the player footage of the level 3 supply chains, the glass works is a green Commoner (level 2) building, so a settlement you have leveled to Village can host it — the demo cap is enough.

How to add the second glass works

1. Level the settlement to 2

   Fulfill every Food and Equipment need in the settlement panel, then click Level up next to the mayor portrait. Glass works sit in the Commoner tab, which appears after the upgrade. The mechanics here come from the developer's own FAQ on the County of Fortune Steam page.

2. Unlock a free building slot

   Each class has its own slots, and supplying equipment unlocks the next one. Keep the equipment needs supplied — at level 2 and above, extra equipment also raises the worker cap in buildings, which helps the new works run at full staff.

3. Pick a mayor who is good at glass

   Hover over the building icon in the slot list to see whether the current mayor shows a bonus for it. A mayor with the glassworks skill runs it at far higher efficiency; in the video the player promoted an available mayor with that skill rather than relocating a region leader (region leaders cannot be swapped out).

4. Secure sand and potash

   Glass production needs sand and potash. Place or trade for sand near the settlement, and set up a trade route (shortcut T) from a region producing potash — the video shows a soap-producing region shipping potash to the glass works. Heavy goods like sand move by river, so check the flow direction first.

5. Place the glass works

   Open the Commoner tab, click the plus sign in the free slot, and select the glass works. Once built, it produces glass for glass tableware and lamp workshops downstream.

If it is not producing

A production building shows a warning icon when an input is missing. If glass output stays low, check that both sand and potash are actually arriving: open the trade overview, confirm the routes exist in the right direction, and watch the balance.

Traders like to hold a surplus, so a route sitting at roughly plus five may not deliver enough until production rises. The player video solved a shortage by simply adding a second glass works in another settlement with an open slot and a glass-skilled mayor.

FAQ

Is the glass works available in the demo?

Yes. It is a Commoner (level 2) building, and the demo allows leveling to 2, so you can build it there.

Why can't I place a second glass works?

The settlement has no free Commoner slot. Supply equipment to unlock the next slot, or level another settlement and build there.

What does a glass works need as inputs?

Sand and potash. Sand can come from a local sand pit, while potash usually needs a trade route from a producing region.
