Natural Generation

Clay is a terrain block variant created during world generation. Clay deposits are found in any area with high enough precipitation (so not deserts) and high enough temperature (so not the arctic). They can be found at any elevation. You may notice them on the map as semi-circular spots of a slightly different color from surrounding grass. The deposits are disc-shaped and that disc follows surface deformations. The thickness of the disc can vary between 2 and 4 blocks.

Clay Types

There are two type of clay blocks: blue clay (appears pale blue) and fire clay (appears pale pink/beige). Both blue clay and fire clay are found in the same climate. Blue clay is 5 times more frequent than fire clay but fire clay has slightly larger deposits (15 blocs radius against 13 blocks radius in average).

There are also items made out of brown clay and red clay. But those are only available by purchasing them from Traders (Building Materials) or by finding them in ruins .

Grass Variants

Clay blocks have grass coverage variants and may appear as "bare clay" with a surface colored according to the clay type (no grass), or a green top surface, aka "grass block". Depending on climactic conditions, grass coverage appears sparse (patchy green) on clay blocks. Tall grass may also grow/spawn on "grass" blocks.

Obtention

Harvesting

Clay blocks may be removed by breaking with an empty hand or using any tool, though a shovel is a faster method to harvest clay blocks. When broken, clay blocks drop 4-5 units of clay, which stack to 64 and may be carried in player inventory, or stored in stationary containers. Clay blocks may NOT be harvested intact and replaced elsewhere.

Looting

Stacks of clay are sometimes found in cracked vessels (forage) in ruins .

Usage

Blue Clay

Blue clay can be used to create:

Items requiring no cooking

• Empty skep
• Empty beenade
• Light mudbrick
• Dark mudbrick
• Mudbrick slab
• Cobblestone
• Cobblestone stairs
• Cobblestone slab
• Slate roofing blocks (5 versions)

Items requiring to be cooked in a firepit

• Hardened clay

Clay requires a temperature of at least 300°C to cook.

Items requiring to be cooked in a pit kiln

• Clay brick which is used to craft:
  • Clay bricks
  • Clay brick stairs
  • Clay brick slab
  • Clay brick chimney this decorative chimney is unlit and does not produce any smoke, but there is a lit version that can be found in ruins .

• Items created with the clay forming mechanic:
  • Tools and weapons molds

• • Cooking pot
  • Crock
  • Bowl
  • Jug
  • Watering can
  • Crucible
  • Planter
  • Flowerpot
  • Storage vessel
  • Clay shingle which is used to make Clay roofing blocks (5 versions).

Fire Clay

Fire clay can replace blue clay for the creation of all the items from the previous section. However, only fire clay can be used to make:

• Clay oven
• Fire clay brick that is required to build the bloomery for ironmaking.
• Tier 1-3 refractory brick that is required to build the cementation furnace for steelmaking .

Storage

Clay blocks technically stack to 64 but they cannot be obtained through normal survival gameplay. Clay bits can stack up to 64.
