Marble incense burners are pieces of furniture that can be built in the chapel of a player-owned house through the Construction skill. Lit incense burners improve Prayer experience gained when using bones or demon ashes with the altar in the room by an additional 50% per burner. Note that though marble burners require the highest level to construct, all three types of incense burners — oak, mahogany, and marble — all yield the same experience bonus and remain lit for the same amount of time.

The player must have a tinderbox (tool belt works) or dwarven army axe and a clean marrentill to light a burner; for the maximum Prayer bonus, both burners must be lit.

The burners burn for 2 minutes and 10 seconds before they burn out. If there are no other people in the player's house, they will not stay lit.
