Why Do Candle Jars Turn Black?

Oct. 15, 2021

Candles are a great way to add ambience to a room while also providing a pleasant scent in the process. They come in a wide range of scents and colours to suit whatever scent or mood you happen to want. However, sometimes candle jars can start to turn black. It is unsightly, makes the candles look dirty and they usually need to be thrown away. So what's going on and what can you do about it?

When you light a candle for a while and start to notice a black colour on the side of the jar, this is carbon at work. The flame produces carbon and the bigger the flame, the more carbon there is. The black colour you see in the jar is due to a lack of oxygen. A candle jar will only produce carbon without the necessary flow of oxygen and will burn. The updraft of these hot gases from the combustion makes the oxygen flame insufficient and prevents the diffusion of air. The black colour you see in the canister is due to the lack of oxygen.

This results in the burnt black appearance that becomes common inside the candle. Unless you are an amateur candle jars supplier, you may not be aware that there are actually proper ways to combat the carbon combustion that produces the black, burnt appearance we all hate so much.

 

The right way to burn

Believe it or not, there's more to lighting a luxury candle than simply lighting the wick and letting it go. Of course, you can do this, but before long you may end up with those black marks on the side of the candle jar. Firstly, when you first use it, you should burn it for about two hours or so. This helps to prolong its life and ensures that you can use it time and time again. Doing this will allow the top layer of wax to melt completely. When you light it next, the melting top layer will even encourage burning.

Tips and tricks for protecting your candle

One of the most common steps to prolong the life of candles is to keep them away from areas where there is not enough oxygen. Without oxygen, candles will not only burn faster and faster, but they will also produce the signature black streaks that we hate. Avoid so-called "drafty" areas; that is, areas where there is no airflow. Getting enough oxygen allows for a cleaner, more efficient burn, which is good for the candle and the jar in the long run. The wick is also essential for the life of the candle. As the candle continues to burn, the length of the wick will increase. This action will allow your candle to burn faster. It is important to trim the wick each time you burn your candle.

 

Generally, you need to make sure that the wick is no more than a few millimetres long, or roughly the same length as when you got it. Keeping the wick short means it won't burn the candle as quickly. This means making more use of your candle. In addition, trimming the wick will prevent the candle holder from becoming too hot and overheating. This helps to prevent black smoke from developing and eventually building up on the sides of the candle jar.
