and a typical thermal conductivity for such ceramic materials is in the approximate range of 0 005 0 001 cal sec cm 2 u00b0 c cm other low thermal conductivity materials include various polymers which term also encompasses polymer based composites such as glass or mineral filled polymers or polymer coated materials such as metals provided that such structures fall within the definition of low thermal conductivity shown in the fig2 embodiment is an electrical heater 28 which is disposed at a bottom portion 35 of an interior volume 37 enclosed by the housing 12 although not shown in this view it is understood that this heater is in electrical communication with a source of electrical power via a power cord or the like as is better shown in fig1 as can be seen from fig2 a scented candle 16 is disposed within the body 12 so as to be heated by the heater 28 as shown the candle 16 includes a wick 30 and a body of scented wax 32 which may at least be partially circumscribed by a body of material 33 since the heater of the present invention eliminates the need for burning the candle the wick 30 may be eliminated it is also to be understood that the body of wax.
