This article is about the Earth resource (clay). You might be looking for the Earth Biome.

Earth

General

Overview

The Claypit is the primary source of Earth. As a polygon building, its production rate scales with area: +0.01 Earth/m²/day in the Wood Biome and Stone Biome, and +0.04 Earth/m²/day in the Earth Biome. The Clay Crane is placed within a Claypit to boost output, producing +20/day in the Wood Biome, +10/day in the Stone Biome, and +30/day in the Earth Biome, at the cost of Tools (-0.1/day). The Improved Clay Crane significantly increases output (+50/+20/+80 per day in Wood/Stone/Earth) but consumes more Tools (-1/day).

The Foraging Hut produces a small amount of Earth (+1/day) in the Wood Biome and Stone Biome, alongside Food and other basic resources. It does not produce Earth in the Earth Biome.

In the Earth Biome, Earth is the primary construction material. Most buildings that cost Wood in the Wood Biome or Stone in the Stone Biome cost Earth instead. The Claypit is not available in the Arctic Biome.

Production

Building	Wood	Stone	Earth	Arctic	Workers	Notes
Claypit	+0.01/m²	+0.01/m²	+0.04/m²	—	-0.01/m²	Polygon building; rate scales with area
Clay Crane	+20	+10	+30	—	5	Child of Claypit; consumes Tools (-0.1/day)
Improved Clay Crane	+50	+20	+80	—	5	Upgraded Clay Crane; consumes Tools (-1/day)
Foraging Hut	+1	+1	—	—	1	Also produces Food, Wood/ Stone

The Claypit has the highest output in the Earth Biome (+0.04/m²/day), 4 times the rate in the Wood Biome and Stone Biome (+0.01/m²/day). The Clay Crane and Improved Clay Crane are placed inside a Claypit and provide substantial flat-rate production, making them essential for scaling Earth output. The Claypit is not available in the Arctic Biome.

Production Chains

Glass Chain

Glassworks

→

Glass

The Glassworks converts Earth into Glass at a rate of -50 Earth/day to +5 Glass/day (10 workers). Glass is required for constructing the University and Museum, and is consumed by the University at -5 Glass/day. This makes Earth an indirect prerequisite for Knowledge production.

Consumption

Building	Rate	Notes
Glassworks	-50/day	Input for Glass production; also consumes Tools (-0.5/day)

The Glassworks is the only building that consumes Earth as an ongoing resource. It converts 50 Earth/day into 5 Glass/day, requiring a substantial and steady supply from Claypits and Clay Cranes.

Storage

Building	Volume
Center	5,000 (shared with all resources)
Square	10,000 (shared with all resources)
Warehouse	5,000 (shared with all resources)
Foraging Hut	100 ( Food, Wood, Stone, Earth)

Other Sources

Trade can be used to buy and sell Earth on the Market (1,000 capacity) or Port (5,000 capacity).
Expeditions yield random basic resources ( Wood, Stone, Earth, or Glass) per area explored.
Celebration events can grant bonus Earth.

Affected By

Effect	Source	Multiplier	Type
Goods production	Dubious Working Rules	×1.2	Policy
Goods production	Worker Safety	×0.8	Policy
All production	New Town Boost	×2	Automatic (4 days)
	Great Federation	×1.1	Alliance type
	Science League	×0.8	Alliance type

The goods production effect specifically targets Wood, Stone, and Earth production. The all production effect affects every production building in the settlement.

Changelog

February 7, 2026

Balance The Iron Mine has been rebalanced: maximum daily production is now 100 / 60 / 40 ( Stone / Wood / Earth biomes). Production in the Wood Biome and Earth Biome is now feasible, though the Stone Biome remains most favourable.

+'''Earth''' (clay) is one of the three primary [[Resources|resources]] in [[Main Page|Project Rebearth]] and the backbone of construction in the [[Earth Biome]]. It is extracted from [[Claypit|clay pits]] using [[Clay Crane|Clay Cranes]] and is the key input for the [[Glassworks]], which converts it into {{Icon|Glass}}. {{Icon|Earth}} is also used as a building material in the [[Earth Biome]], where it replaces {{Icon|Wood}} and {{Icon|Stone}} as the primary construction resource.

+The [[Claypit]] is the primary source of {{Icon|Earth}}. As a polygon building, its production rate scales with area: +{{BuildingData|name=claypit|data=rate|biome=wood|resource=earth}} {{Icon|Earth}}/m²/day in the [[Wood Biome]] and [[Stone Biome]], and +{{BuildingData|name=claypit|data=rate|biome=earth|resource=earth}} {{Icon|Earth}}/m²/day in the [[Earth Biome]]. The [[Clay Crane]] is placed within a Claypit to boost output, producing +{{BuildingData|name=clay_crane|data=rate|biome=wood|resource=earth}}/day in the [[Wood Biome]], +{{BuildingData|name=clay_crane|data=rate|biome=stone|resource=earth}}/day in the [[Stone Biome]], and +{{BuildingData|name=clay_crane|data=rate|biome=earth|resource=earth}}/day in the [[Earth Biome]], at the cost of {{Icon|Tools}} ({{BuildingData|name=clay_crane|data=rate|biome=wood|resource=tools}}/day). The [[Improved Clay Crane]] significantly increases output (+{{BuildingData|name=clay_crane_upgraded|data=rate|biome=wood|resource=earth}}/+{{BuildingData|name=clay_crane_upgraded|data=rate|biome=stone|resource=earth}}/+{{BuildingData|name=clay_crane_upgraded|data=rate|biome=earth|resource=earth}} per day in Wood/Stone/Earth) but consumes more {{Icon|Tools}} ({{BuildingData|name=clay_crane_upgraded|data=rate|biome=wood|resource=tools}}/day).
+The [[Foraging Hut]] produces a small amount of {{Icon|Earth}} (+{{BuildingData|name=foraging_hut|data=rate|biome=wood|resource=earth}}/day) in the [[Wood Biome]] and [[Stone Biome]], alongside {{Icon|Food}} and other basic resources. It does not produce {{Icon|Earth}} in the [[Earth Biome]].
+In the [[Earth Biome]], {{Icon|Earth}} is the primary construction material. Most buildings that cost {{Icon|Wood}} in the [[Wood Biome]] or {{Icon|Stone}} in the [[Stone Biome]] cost {{Icon|Earth}} instead. The [[Claypit]] is not available in the [[Arctic Biome]].
