true - spilled burning coal makes quite a mess. If the hot ceramic hit the floor though I would think a cheaper carpet would have a melt spot in it pretty quick. Probably not that deep, as the exposed surface of the ceramic allegedly gets to about 100 degrees C as compared to combusting coal at 550 - 700 degrees C.
(As I understand it, the air passes through the far-hotter centre of the device so it isn't just the bottom surface heating the air that passes through it)
For those accustomed to imperial, not celsius, 100 degrees C is the temp of boiling water. Imagine a *** of boiling water dumped on your rug - then ignore the afterdamage from the water soaking into the fibres. Temperature-wise, if one did drop the thing on a floor but was quick with the tongs to retrieve it, I would *assume* the damage would be less than coals from a tipped hookah (and yep, I've had friends trip on hoses and send my hookahs arse over teakettle from time to time)
