Crafting
The newly made "Extinguished" torch must be lit either on a firepit, or with another torch or firestarter. However it takes no fuel to use a lit torch to re-light a placed extinguished torch.
Burnt out torches can technically be re-lit in a firepit, however, they cannot be obtained in normal survival gameplay.
Natural Generation
Torches do not appear placed in any ruins, however, extinguished torches do appear as loot in collapsed chests.
Usage
They provide light when put on either off-hand or main hand. They can placed in the ground, the wall or in the torch stand. Torches can be also used for lighting firepit, extinguished torches or setting grass or wooden-based materials on fire. Torches can be used as a makeshift weapon, whilst dealing poor damage has a chance of setting the enemy on fire.
