The Forest glassworks is an Occidental Production building that processes trees into Potash, which is used by the Glass smelter to produce Glass. The Forest glassworks requires 132 Trees within its Influence area to run at 100% productivity.

Just like with other Production buildings that require Trees, if the Influence area of the Forest glassworks crosses the circle of a Lumberjack's hut, Charcoal burner's hut or other Forest glassworks, productivity loss may occur. The second building that was built receives no productivity benefits from the overlapping squares while the first building maintains full productivity benefits from those squares.
