What causes the flame on a gas stove to turn from blue to orange?

I have never had a gas stove before. I noticed tonight while cooking that sometimes the flame is blue and other times it seems to have orange tips. What causes this? Is this typical of a gas stove?

What causes the flame on a gas stove to turn from blue to orange?
There is nothing wrong with your stove or gas supply as some others would have you believe. The 13 year old (although a guess) was closer than most. The orange tips are from impurities burning in the flame. They can be from just about anything such as water vapor from water splashing on a hot surface close to the flame even from dust in the air as well as dirt in the gas line. Try throwing a few grains of salt into the flames and you will see some orange.
Reply:If it's getting enough O2 it will be blue and if it's short on O2 it will be yellow just like most above said. But here is another thought. Did you happen to be using salt in your cooking at the time you saw the orange? Certain types of atoms cause the flame to turn different colors even if there is enough O2. Sodium in salt causes the flame to turn orange, not yellow. Drop a few grains of salt into the flames and you will see them turn orange as the salt passes through the flame.





There are "flame" tests for many elements--if you took high school chemistry you probably performed these tests. They put some of these elements into "color" logs that you can buy for your fireplace to make the flames different colors.
Reply:Air/fuel ratio. If the air is not enough, your flame will turn orange. Adjust the air intake underneath the stove by opening it a bit until the flame is blue. A blue flame is the best because it means good air/fuel ratio and your kettle's bottom will not turn black.
Reply:its normal but if it burns orange all the time it means its not properly vented or not getting enough air.
Reply:low gas pressure, be careful and good day to you!!
Reply:dont know i am only 13 but i think it changes when the gas hit the gases in the air











did you know that 73% of your air is nitrogen
Reply:IT IS A NUMEROUS OF THINGS, IF IT IS REAL COLD OUTSIDE EVERY BODY IS USING AND THE PSI PRESSURE COULD BE LOW, THEN IT COULD BE THE GAS/AIR MIX. ;RIGHT CLOSE WHERE THE BURNER CONNECTS TO THE ORFICE(BRASS FITTING)U CAN TURN THIS SLEEVE ON THE BURNER TILL GET PROPER COLOR. ALSO U COULD HAVE A FOREIGN OBJECT BLOCKING THE PROPER GAS PRESSURE TO THE BURNER. REMOVE THE ORFICE, IT WILL UNSCREW, AND BLOW IN IT BACKWARDS TO FREE IT OF ANYTHING IN IT. HOLD IT UP TO THE LIGHT AND SEE IF U SEE A HOLE IN IT AND THAT IT IS CLEAN. GOOD LUCK
Reply:Perfectly normal, blue is fully oxidized, red is a partially oxidized flame. You'll find it cooks much better than an electric stove.
Reply:Yes it is. Blue flame indicates the cleanest burning rate for gas. Yellow or orange tips indicate it is burning dirtier - a function of too little air of something else added to the burn, like water, grease, etc.
