My Time at Sandrock · Machine upgrade
Civil Furnace
The Civil Furnace expands furnace production to include marble bricks, tempered glass, soup pots, manganese steel bars, steel bars, and chromium steel bars.
How it works
The machine upgrade table lists these components as Civil Furnace outputs and identifies their material requirements. The guide says each higher-level machine can make everything from the machine before it, plus additional components. It describes research and construction generally, but the supplied passage does not state the Civil Furnace's research cost or construction recipe in its component table.
