A great thing for camping in the woods that won’t set the surrounding place on fire. Would use the construction menu and be made of about… ten(?) rocks. Functions similarly to a wooden stove or a fireplace, but will give off smoke. Not as much as the brazier, though. Also would stop the fire spreading to other tiles, so would be safe to use inside.
Yeah, a camp fire isn’t a great thing to be using inside a house, but I’ve seen many people stack a few things around a space and toss in some wood then light it. In a house.
Don’t ask me why that happened. 
Also, what are the floors in cata made of? Wood? Carpet?
