The Charcoal Kiln is used to create Coal from wood. It converts single units of Wood, Fine wood, or Core wood into coal at a rate of 1 every 16 seconds.

It can hold up to 25 wood at a time. When adding wood to the kiln, the game will prioritize wood from the player inventory in the following order:

  1. Wood
  2. Fine Wood
  3. Core Wood


The Charcoal kiln is unlocked when the player acquires a Surtling core. A nearby Workbench is required to construct it.

Kilns can be placed directly onto terrain and stone structures. Currently, they cannot be placed on wood structures but it is possible to bypass this to a extent by terraforming terrain with a Hoe to be in line with wooden floors.


  • Like other structures that process materials, Charcoal kilns are sped up with the passage of time that happens when the player is sleeping.
  • When destroyed with a Hammer or other means, it drops all materials used. It is therefore possible to alternate between using a Smelter and the Charcoal kiln, reconstructing them as needed.
  • Active kilns have the same effects as a Campfire, providing players with heat as well as scaring away the appropriate monsters, albeit with a smaller radius (?).
