Tonight I encountered a peculiar structure that contained a woodburning fire. The angled edges converge to a square exhaust in the shape of a prism. The picture below shows this structure.
I asked many bystanders and even those tending the fire, but nobody seemed to know what to call this steel structure. So, what would I call it?
One man was sure it was an urn, but I would think those would be open topped and circular. Would he be right?
