Soul Campfire

Soul Campfire is also a game feature of Minecraft.
More information can be found on the Minecraft Wiki

A soul campfire is a dimmer variant of the campfire with turquoise flames. Soul campfires deal more damage than normal campfires. Just like normal campfires, it can be used to cook food, pacify bees, act as a spread-proof light source, smoke signal or damaging trap block.
