What causes candle jars to catch on fire?

There can be multiple reasons as to why candle jars tend to catch fire and you need to be aware of those. 

Contaminants: 

Cheap candles might have a lot of additional chemicals and contaminants present in the wax. This can cause the entire wax to light up in flames instead of just the wick. 

This often happens if you are burning a very old candle or if your candle has additional decorations such as petals or seeds. These usually trigger the whole wax and jar to catch on fire. 

Fragrance:

Another common cause is if there are too many chemical fragrances added in it or even essential oils. This can trigger bigger flames and as a result, cause your candle jar to catch on fire. 

Burning the last bit of wax:

It is always recommended to never burn the last bit of wax present in your jar. The last one centimeter or so can get heated to very high temperatures and start a candle fire in your jar. 

Too many wicks:

There are candles present nowadays that contain three or more wicks. This is extremely dangerous because the amount of heat that is generated due to the fire can cause a candle fire to start in your jar. 

It is always best to use candles with one wick. 

Glass jar explosions:

Even though glass jars are fireproof, it does not mean that they cannot start a candle fire. Many cheap candles are not manufactured properly. 

Either cheap glass jars are used that overheat very easily or the candle wick is not made properly and the fire ends up touching the sides of the jar. This can cause the glass jar to overheat and explode and as a result, start a candle fire.
