No. It isn't fire, it's just an illusion that looks like fire.
If an everburning torch looks like a regular flame, but it creates no heat and doesn't use oxygen - will it ignite flammable gas?
Everburning torches are based on Continual flame. Continual flame reads.
A flame, equivalent in brightness to a torch, springs forth from an object that you touch. The effect looks like a regular flame, but it creates no heat and doesn't use oxygen . A continual flame can be covered and hidden but not smothered or quenched.
Since its not using heat or oxygen i don't see any mechanism for it to set off the gases
You could use the torch as the drill portion of 'Rubbing Sticks'... but the heat and friction is what causes ignition, not the torch. :D
