What Does the Colour of Your Flame Mean?

As the temperature began to drop, we are all looking for warm and cosy nights especially during winter.

This is the perfect time of year to get your fireplace up and running or even enjoying your outdoor space while you sit with family and friends around a roaring fire pit in your back garden. But, how do you know if the fire you have built is safe, long-lasting, and provides the best option for air quality protection?

Here is Your Winter Guide to knowing your Flames

Vibrant Orange and Illuminating Yellow

This is by far the most obvious and common colour that you will be seeing. The beautiful flickering, warming sparks of orange is usually the most traditional colour flame associated with open fires.
The bright orange is a result of unburned carbon compounds and sodium present in the wood. Good quality firewood when burnt will give off an orange or yellow flame; this is an indicator that the fire will burn stronger and more consistently.

It is the orange or yellow flame that is also the best source of fire for cooking, barbequing or grilling.

Be Cautious with Red

If the flame turns from an orange to a bright red, that is more problematic. This is a reflection that the flames are not receiving enough air for complete combustion to occur, it contains large traces of carbon monoxide and can be terribly unsafe if inhaled.

Bold and Blue

What Does the Colour of Your Flame Mean?

A blue flame is the result of gases such as natural gas, propane, ethane, and methane being burned. Blue flames tend to be more resourceful; they are an indicator that the gas is experiencing complete combustion. This is often associated with gas stove cooking or furnaces and is a proven source that the right air to fuel blend has been achieved. The colour blue is a direct result of the carbon compounds, which are burned successfully.

In essence, the colour of the flame is the direct result of the temperature of the fire, the source of fuel you have used or a reflection of the combustion levels. Blue is by far the hottest flame, yellow comes next, then orange and eventually red, which is definitely the most toxic and therefore not advised. You will see blue flames burn as a result of the gases used, while the yellows, oranges and reds are usually a result of burning wood, candles or coal.
