Magic Lantern

Wooden body, viewed with open door.

With the door open, the lamp housed within the body can be seen clearly.  Smoke generated inside the lamp can exit easily through the smokestack, which is just above the top of the lamp.

Notice the white rectangular platform at the base of the lamp.  This is likely a piece of thick ceramic tile, a material that does not conduct heat very easily.  The wooden body is lined on the inside by flat sheets of metal, serving to spread the lamp's heat along a wider surface of the wood so that no single point becomes too hot.  Also notice the distance between the lamp and the surrounding wood.  These features help make it possible for the magic lantern to have a wooden body, but still not catch on fire easily.
