- To burn, an object needs to be heated to a certain temperature. While burning, the object will generate more and more heat until it's spent. The heat will dissipate normally, which can raise the temperature nearby enough to ignite other objects. The hotter something is, the faster it burns. When an object is all burned up, it no longer generates heat. some types of ashes can start burning again if heated even more.
- This is why kindling, which is easy to ignite, is used to set other things on fire. It's also why this can be so difficult to do--a burning tree will ignore nearby clothes, which burn hotter and faster than the tree does, but will not bones. (I even tried lighting all the other plants and trees on fire, and I still couldn't get the bones to start burning. Grass burns very hot fast, generating a lot of heat that dissipates just as quickly. Mine fires burn cooler and slower, to the point the coal could possibly be better described as 'roasting'. The heat does not dissipate easily, however, and can be very dangerous. I can't really answer your question, and I'm not totally sure the model I described is accurate, but I hope this explanation helps anyway. --Navian 16:38, 13 November 2008 (EST)
