I belive it is gross. Just remeber fire and brimstone :-)

Pine cones will create some nice colours in the flames.\n\nYou can treat dry pine cones to produce various colours of flames.  Most of these ingredients can be found in the laundrey section of your grocery store or farm supply stores.\n\nBorax = yellow/green\ncopper sulfate = green/blue\ncalcium sulfate ( epson salts ) = white\nCalcium cloride ( pure only , a bleaching compound ) = blue\n3 parts potassium sulfate/ 1 part potassium nitrate = violet\npotasium  cloride = purple\n\nChoose one colour...do not mix colours\nDisolve as much of the colour as possible in a bucket as you can.  ( typically 1/2 pound of colourant to a gallon of water.)\nMix well\nToss in clean dry pinecones and soak overnight.\nRemove and spread on newspaper for at least 72 hours to dry.\n\nToss in your fire and enjoy the colours.\n\nYou can also achieve the same results by dipping pinecones in parrafin wax and sprinkling with the powdered colourants while the wax is still wet.

it's the same with a flame as well, I would assume that the heated gasses that burn off last are what causes it to be hotter.

Well, if you're considering burning fossil fuels like coal and oil, then it wouldn't pose much danger because they only release carbon dioxide and water vapours into the atmosphere and this release of CO2 apparently helps to maintain the CO2 cycle.\nHowever, there are organic compounds (some used as fuels), including polymers like 'polytetrafluoroethene' that are non-biodegradable and so cause a litter problem in landfill sites. And if we burn them, they release toxic gases like carbon monoxide which can cause cancer and hence damage the environment.

The visible "flame" is actually light being emitted by things getting hot in the region that is burning.  In a pure hydrogen/pure air flame, the flame is almost invisible (which makes it very dangerous).  In a flame from a wood fire, we are seeing the emissions from the cellulose the wood is made off, plus lots of other compounds. In a natural gas flame they put extra chemicals in the gas to create colour and smell to make it less dangerous.  \n\nAll the colors we think we see are actually light either being reflected off of things (the light comes from the sun or a light bulb), or light that is being emitted from the source itself.  The color of the light can often tell you what atoms were in the thing burning.\n\nYou should encourage your boy, he sounds smart.  (Unless he's already 18, LOL!)

Fire is a process of Oxidation.  \n\nIt's temperature is equal to or greater than the Auto-Ignition Point for the fuel substance.  Each Fuel will have it's own unique Auto-Ignition Point.\n\nIt's color is determined by the elements present, and the visual spectrum of thier discharge photons...  Photons are discharge as the electrons jump from high to lower excitation levels, and each element has it's own color signature.\n\nMost fires are orange yellow and white because of the large ammount of Hydrogen in the combustion process of organic (or formerly) material.  Occasionally Red will come out thans to the carbon of the same.\n\nIf you add powered metals to the mix your flame will change color.  Copper makes a pretty green for instance...

ITS PEOPLE LIKE YOU THAT CAUSE ALOT OF FOREST FIRES... MOST CARS COME WITH AN ASHTRY, USE IT AND EMPTY IT WHEN YOU GET WHERE EVER YOU ARE GOING...AND IF YOU DON'T LIKE THE SMELL, CONSIDER QUITTING, THAT WOULD SOLVE ALOT OF PROBLEMS.

Flame tests are "OK" when you are dealing with a reasonably pure solution.  If there are more than one cation present, such as sodium and potassium, then the resultant color in the flame will not be so determinant.  Also, if you are color blind flame tests suck.

Fires need oxygen to burn.

because it contaminates the color of the flame and produces a differently colored flame then say a hydrogen flame which is colorless

Well, a blue flame is the most efficient burn and the hottest no matter what your combustible matter is.  At what temp that is, I don't know.

i wouldnt worry about that.  what you should be concerned with is the toxic gasses coming from the burning plastic.  you can literaly die from some of the more exotic stuff you could accidentally breathe in.
