A torch will break instantly and drop itself when broken using anything. The tool will not take any damage when breaking the torch.
Torches will also be broken if flowing water runs over its location.
Crafting a torch takes a twig and a coal.
Torches can be placed on the top or the sides of all objects. Being non-solid, torches have no collision box.
Gravity affected objects like sand and gravel will not fall if the object below them has a torch on it, and will break if they fall onto a torch.
