Stands like this one bearing a king's name would have been associated with a god's temple or royal funerary complex, but the best evidence for use and placement of such stands comes from private tombs where they are documented as having stood on either side of an offering table or offering slab in front of the false door.
Middle Kingdom evidence indicates this type of offering stand held mainly incense. The incense coals may have been placed in a pottery bowl or directly on the stone. Food placed on the adjacent offering slab was first passed over the incense to aid its transmission to the god or deceased person to whom it was offered.
