You can grow a tree and fireproof it. Or find something with a pretty high combustion point and internalize the tree with. PERHAPS the tree won't burn. =)

Charcoal powder will burn very well.\nThe flame used to ignite the powder will not be affected and will not change color.\nThe charcoal dust will burn yellow/white.  It will be that color because your experiment lacks enough oxygen for it to burn blue.\n\nOther dusts are very flammable and sometimes are explosive.  The dust from grain when stored in a silo is extremely flammable. Silos across the country explode every year.\nCoal is crushed into dust and blown into the furnaces at electrical power plants.  The heat makes steam for the turbine/generators.  \n\nI would like to suggest some experiments with common powders to see how well they burn.  But I singed the hair off both hands, my brother singed off his eyebrows, and we decided playing with fire was (though great fun) rather stupid.

Following the end of the eruption, the islanders used the heat from the slowly cooling lava flows to provide hot water and to generate electricity. They also used some of the extensive tephra fall of airborne volcanic material to extend the runway at the island's small airport, and as landfill on which 200 new houses were built.

Farmers, pyro technicians, chemical engineers, and many other professions utilize potassium in their line of work for various purposes.  For example, farmers use potassium-containing fertilizers to assist in crop growth.  On the other hand, pyro technicians use potassium in their displays because of its ability to oxidize the firework mixtures.

Use chicken wire to make a volcano like thing, then cover it with plaster. paint it and add trees and stuff like that. then mix vinegar, red dye and baking soda together to make the lava.

Sell them to a company that shreds them and mixes them with concrete to make highways.  It's good for the environment.

Lava or pumice which is formed in a volcanic eruptions has air pockets in it. If smothed on one or two sides it could be used to cool dinner.

considering ur trying coal or other burning material as fuel.\n\nif the ash content is more means then the heat conductivity will be less from core of the fire.\n\nash is formed due to loosely packed material and has very less heat in it.\n\nash has less sp.heat capacity.

hardwood such as oak or maple. \nEucalyptus burns really hot and smells good - but the creosote will build in your chimney,
