We know that fire comes in different colors as it can be orange, red, yellow, and blue, but what color of fire is the hottest temperature?
We notice that fire is different colors in different situations, as fire can be orange or yellow when it is burning materials, or it can be blue when we are using a gas stove.
As the fire is different colors, this indicates that they are not the same temperature, but which is hotter?
This article will explain what the hottest color of fire is and how hot blue fire is. Find out more about what different colors of fire mean and how fire differs in color based on the temperature.
How Does Fire Change Color?
Fire is a very common element and it is often used daily for cooking, in barbecues, or fireplaces.
As we are so used to seeing a fire, it can be surprising that it can come in so many different colors.
As fire can be different colors, how does it change and what does it mean when a fire is an unusual color?
The reason that fire can change color is because of either the chemicals that are burning or the temperature of the fire.
These factors can influence the color of the fire and cause it to become a color that we might be unfamiliar with.
You may never have heard of green fire or indigo fire, but it is all down to either the chemicals, the temperature, or both.
How Hot Are The Different Colors Of Fire?
Fire can come in lots of different colors, but how hot are they?
You can find out more about how hot the different colors of fire are below and if the color of fire always shows how hot the fire is.
Yellow Fire
Yellow fire is very hot and it can give off a maximum heat of 2,200 degrees Fahrenheit. It is extremely hot and cannot be touched as it will cause burns.
Blue Fire
Blue fire is a lot hotter than yellow fire, and it can reach temperatures of 3,000 degrees Fahrenheit.
This is why blue fire is effective for cooking as it is a lot hotter and reduces the cooking time that would be needed if a cooler flame was being used instead.
Violet Fire
The hottest fire out of all the colors is violet fire as it has temperatures that are hotter than 3,000 degrees Fahrenheit.
As you cannot get a fire that is hotter than violet fire, it is used to work with porcelain, steel, and iron.
White Fire
White fire is known for being extremely hot and can burn as hot as 2,700 degrees Fahrenheit. As white fire is so hot, it can burn through nickel, cobalt, and even uranium.
Indigo Fire
Indigo fire is used when working with iron and glass as it can burn up to temperatures of 3,000 degrees Fahrenheit.
Although blue fire also burns at 3,000 degrees Fahrenheit, the heat output of indigo fire can be controlled easier.
Orange Fire
When common materials are burned, it will produce an orange fire.
Orange fire can burn at temperatures reaching up to 2,000 degrees Fahrenheit and it can melt strong materials such as copper and gold.
Green Fire
Although green fire is not as commonly seen as other colors of fire, it is still a color of fire that can be seen.
There is no telling how hot green fires are, and instead of showing how hot the fire is, it indicates that chemicals are burning.
The temperature could be extremely high, so you should never go near green fire.
Red Fire
Red fire is the least hot compared to all of the other colors of fire, but that doesn’t mean that you should try touching it as it is still extremely hot.
Red fire burns at an average temperature of 1,500 degrees Fahrenheit and it can melt materials like tin, glass, and zinc.
What Is The Hottest Color Of Fire?
As it is the first color on the spectrum, violet fire is the hottest color. Although all types of fire are hot, the violet fires are the hottest and need to be carefully controlled.
Despite this being the hottest color of fire, this doesn’t mean that other colors of fire can be used irresponsibly because they are not as hot.
You need to be careful with all colors of fire.
What Color Of Fire Is The Most Common?
The most common color of fire is orange as it is the color of fire that people often see when they are burning something.
Materials like wood, charcoal, and paper are all things that are used for burning and they are seen in fireplaces, fire pits, and barbecues.
The thing that all of these materials have in common is that they all contain carbon.
As all of these materials contain carbon, the color that they produce when they are burning is orange.
This is the main reason why orange is the most common color of fire as it is the color that people see in their daily lives.
Blue flames are not as common overall, but they are common for people who use gas stoves since when you turn on the knob, you will notice that the flame is blue.
The reason that blue flames are used for cooking is that they are incredibly hot, and using a cooler flame would result in more cooking time.
Do Chemicals Affect The Color Of Fire?
Chemicals can affect the colors of fire as the particles from certain chemicals can turn fire a different color when it is combined with the heat that the fire is burning at.
There are lots of different chemicals that affect the color of fire, but what are they?
Yellow fire can be influenced by chemicals like sodium carbonate and sodium chloride, blue fire can be influenced by copper chloride, and violet fire can be influenced by a mixture of potassium sulfate and potassium nitrate.
The chemicals that create green fire are copper and barium, white fire is magnesium sulfate, orange fire is carbon, and red fire is strontium chloride.
As mentioned previously, the color of green fire is not linked to the temperature since green fire becomes green solely based on the chemicals that are burning.
Other colors of fire are due to the chemicals that are burning combined with the heat that they are burning at.
What Is Violet Fire Used For?
Due to how strong and high the temperature of the violet fire is, it can melt almost any material that it is placed in front of.
The strength of the fire means that it is popular to be used in factories to melt strong materials, since other flames don't have the same power to do that.
How Is Blue Fire So Hot?
The color spectrum begins with violet, indigo, blue, green, yellow, orange, and red. When you follow the color spectrum from left to right, Violet is first.
This is why violet fire is the hottest fire as it is at the beginning of the spectrum where there is a higher frequency at the start compared to the end.
Blue light is at the start of the spectrum, so there is a high frequency that gives the blue fire a lot of energy.
There is also a high oxygen content in a blue fire that causes the flames to be very hot, so this is the reason that blue fires are extremely hot.
Can Fire Be More Than One Color At The Same Time?
A fire can be more than one color at the same time. This comes down to the size of the flames from the fire and the materials that are used to start the fire.
You might notice that there is more than one color present when you are looking at a fireplace. The bottom of the fire is blue, and the flames at the top are orange or yellow.
This is due to the temperature of the fire. The blue fire is present at the bottom as this is where most of the heat is, and as the temperature decreases, the flames become yellow.
Remaining Safe Around Fire
When you are around a fire, it is always important to remain as safe as possible to avoid any accidents.
If the fire is used irresponsibly, it can be fatal, so you always need to make sure that you take the right safety precautions.
Keep A Safe Distance
You should always keep a safe distance away from fire. You want to make sure your clothes don't catch on fire or sparks jump from the fire to you since not getting burned should be a top priority.
Always Put The Fire Out
If you are having a barbecue or using a fire pit, you always need to make sure that you have put out the fire once you have finished.
Leaving the fire can cause the flame to become out of control and this could cause a larger fire to occur.
Final Thoughts
To conclude, violet fire is the hottest color of fire that you can get, and red is the coolest out of all of the colors of fire.
The color of fire can be due to the temperature of the fire or the chemicals that are burning, or possibly a combination of both of these factors.
Blue fire can reach temperatures of up to 3,000 degrees Fahrenheit, making it extremely hot.
As it is at the beginning of the color spectrum, the same as violet fire, it is one of the hottest colors of fire that you can have.
