Making fire
Start a fire and keep it under control.
Torches give light but no heat. Use a Flint Striker to start your first fire. One is in your starting pack, and you can make a replacement from 4 Stone by hand.
Start a fire
- Put a pile of Wood or Coal where you want the fire. A single cell of fuel may burn out before it lights anything else.
- Use the Flint Striker on the pile. It heats the fuel enough to ignite it. Stone, dirt, and metal will not light because they do not burn.
- Keep other flammable things away. Fire heats nearby cells and can spread to your bed, workbench, or wooden base. Build around a fireplace with stone or another material that does not burn.
Water puts out fire on contact. Use it if a fire starts spreading where you do not want it.
Fuel and heat
What you burn determines how hot the fire gets and what you can smelt. Wood leaves Wood Ember; coal leaves Ember.
| Burn this | Catches at | Leaves | Which sits at |
|---|---|---|---|
| Wood | 80 °C | Wood Ember | 130 °C |
| Coal | 90 °C | Ember | 185 °C |
| Leaves, cotton, rope, straw | 60–95 °C | Fire | 205 °C |
| Fuel | 135 °C | Fuel Fire | 202 °C |
| Coke | 150 °C | Coke Ember | 215 °C |
Leaves and cotton reach 205 °C because they burn as open fire, but they do not last long. A coal ember bed stays at 185 °C. That is hot enough to melt copper at 165 °C, but it will not melt iron at 190 °C, no matter how long you wait. See Ore into bars for smelting temperatures.
