They work decent on the older style electric stoves with the wire coil conductors. The glass tops suck because they use infrared elements of some type. The pan has to be in contact with the surface to conduct the heat...hope u get to use them soon Marshy - could try them over charcoal, fire... or maybe even and electric element. u know, those that are independent and u plug them in. not sure how hot the pan would get, maybe not as hot as over gas... but surely hot enuff for some...
hash n eggs, or eggs n cheese!
My wife might frown on me lighting a charcoal fire on top of her stove.
