First a question, since all of the rings of power are accounted for at the beginning of the LOTR (the nine men's are on the nazgul, the seven dwarves are in sauron's keeping the three eleven are on Elrond's Gladriel's and Gandalf's fingers and the one is in Frodo's keeping) how exactly does anyone know that dragon fire will melt the lesser rings?
on the main note of this post I seem to recall that there were two kinds of dragon fire in ME. Most dragons fire was red-orange-yellow and I tedn to think that this was simply ordinary fire. But I beive tolkein said that some dragons could also breathe Green flames. Since fire does not, under normal circumstaces burn green (unless the dragons were eating a LOT of copper salts) I think that those flames may have had some sort of additonal power and could be considered "magic" in some manner." As for the Dragonproof armor of The Dwarves I've always just assumed that dwarves, being wise in nature of minerals simply know where to find asbestos and how to wave it into fireproof cloth which could be incroprted into armor. I also seem to recally that a key part of the armor was metal scrresn over the visors which gave the dwarves the advatage of being able to see through the dragons fire without buring their faces off
