I know blue fire is hotter then red, orange and yellow. But what is the hottest flame color?

white. \nBuring magnesium is white hot, and believe me you wouldn't want to be near it when it does go up.  It is hot enough to break down the molecular structure of water into oxygen and hydrogen and then ignight the following gases.  Firefighters usually have to find other means to fight magnesium fires other than using water.

fire is the heat let off by oxidation (bonding oxygen to other compounds) since the oxygen in water is already bonded to hydrogen it can't be used in the oxidation of the fuel of the fire. water w/ it's high heat capacity absorbes a lot of energy  and also prevents oxygen from getting to the fuel.

What we call fire is actually an ongoing chemical reaction.  The chemical reaction produces heat, light and ash (in simple terms).  We see & feel the light & heat and call that fire.  The reaction can be one that occurs very rapidly, we call that an explosion.  Or it could occur more slowly, like the way charcoal burns.  But generally we call fire the reaction that proceeds fast enough to cause flames but not so fast as to create a pressure wave.

Salt compounds can produce different flame colors when ionized under extreme heat (such as blue bunsen burner flames). At that temperature, it would be a fire hazard to the house, but just for your information, \n\nworks for Chloride AND Nitrate salts.\n\nCalcium-Orangy Red\nStrontium-Pure Dark Red\nLithium-Radioactive Red\nPotassium-Pinkish Purple/Fuschia\nBarium-Green with yellow tint\nSodium-Yellow/Orange\nMagnesium-Light Orange\nCopper-Radioactive Green

Try doing flame tests; adding certain compounds to fire make really awesome colors; it's kind of like putting on your own fireworks show.  Check out http://webmineral.com/help/FlameTest.shtml

Candle flame is a low temperature flame. You can just insert your finger rapidly into the flame without getting burnt. I have also seen people in India keeping burning camphor in their palm (standing in front of deities) as a sort of worship.\n\nNormally, yellow sooty flames will have low temperature and blue flames such as Bunsen flame will have high temperature (around 700 degree C). Welding flames will have around 1200 deg. C, if I remember well.

Fire is a chemical reaction between Oxygen+Heat+Fuel

Lighter colors reflect sunlight .Trust me ,I have owned a black truck and they get damn hot.Lighter ones get hot but nowhere near as hot as a dark one

Light has different frequencies. The higher the frequency the more particle there are in that light spectrum. Purple is the highest visible spectrum and red is the lowest. So because more light particles hit an object in the blue spectrum than the red spectrum the blue spectrum will generate more heat.

A flame is a mixture of gases undergoing a chemical reaction that gives off enough heat to continue the reaction in the molecules that have not yet reacted.  We get the impression that solids (like wood) burn, but it's really mainly the gases coming off of them that burn.  That's why it's easier to start a hot piece of wood on fire than a cold piece of wood.  The initial piece has to be hot enough so that the flamable products escape from it in vapor form.

Any soluble sodium compound like sodium chloride, sodium acetate, sodium bicarbonate (sodium hydrogen carbonate), sodium carbonate, things like that turn a flame yellow-orange.  \nSoluble calcium compounds like calcium nitrate burn red-orange.

Strontium gives a characteristic red in the flame tests, this is due to the spectroscopical properties related to the element itself.\nSome sites explain the subject in detail, for example:\nhttp://en.wikipedia.org/wiki/Spectroscopy

When fire burns it burns oxygen which is given off in the form of heat, so when you add more feul (oxygen) to the fire it gets hotter.

Watch channel 9 news  they will show you and tell you when you can burn fire places they are blue days red days you can`t burn wood. after July 1st next year you may not be able to bur fire places at all

you need three things to create a flame:  heat, oxygen, and fuel.  In the air, you have oxygen.  The phosphorous is the fuel, so if you apply a heat source, you will see a flame.  I don't know what makes a firefly glow.

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.

Blue IS calming.  Studies have shown that blue calms, yellow and orange excite, and red tends to anger.  (This is especially true when painting a baby's room)  However, green promotes thought and is also calming so I'd go with green.
