8 Best Candle Facts You May Not Know

If you’re interested in finding out some interesting candle facts, then our article ‘8 Best Candle Facts You May Not Know’ will be right up your street. So here’s our pick of the most interesting.

1. You May Have been Burning Your Candle All Wrong

Candles must be burned properly to get the most out of them and for safety reasons.

Candle wax has what’s called a memory. That means that when you burn a candle and then extinguish it, the next time you burn it, the wax will melt across as far as it did the first time.

This is why it is so important to allow candles to burn all the way across to the edge of the container the first time you burn it before putting it out. This ensures that your candle does not “tunnel” as it burns, leaving wax along the sides of the container.

A good rule of thumb is to burn your candle 1hr for every inch wide that the candle is. So if you have a 3-inch wide candle, you may need to burn it for at least 3 hours for a good melt pool.

2. A Candle Maker is Called a Chandler

It derives from the Old French word “chandelier”, which, before the advent of electricity, was a ceiling fitting made of several candles.

3. A Candle Flame Doesn’t Always Point Up

Normally, a candle flame always points up because it warms nearby air, which rises up and is replaced by cooler air. This constant cycle (the convection current) creates the teardrop shape of a candle flame.

Under microgravity, (i.e. on a space station) NASA scientists revealed that a flame will be spherical. This is because there is no gravity, therefore the heavier, colder gases would not be pulled down and no convection current would be created.

4. Extinguishing a Candle by Blowing it Out Isn’t the Best Method

Blowing out a candle is an easy way to put out your candle. But it’s not the best! This results in black carbon dropping into the melt pool which isn’t ideal. The best way to extinguish a candle is by using a candle snuffer which is freely available at good online stockists.

5. Candles Have Been Made Out of Animals, Insects and Whales

Tallow (a byproduct of beef fat rendering) was popular in Europe in the Middle Ages, but candles have also been made out of wax gathered from insects and moulded with seeds, spermaceti from sperm whales, beeswax, and various different plants.

Candles are now mostly made from paraffin (a solid extracted from crude oil), beeswax or our personal favourite soy.

Always be careful to check with the soy candle seller that no animal additives are used in the soy wax mix if this should be important to you.

6. No Smoke! A Candle Should Not Smoke.

When a candle is smoking, it means the wick is too long.

This is an easy fix. Extinguish the flame and wait for the wick to cool. Trim it to about 6 millimetres long.

7. Here Say…Freezing a Candle Won’t Make it Last Longer

Many people say that freezing a candle before lighting it will make it last longer. This is fake news.

Freezing the candle may make the wax crack and damage the candle.

8. What Causes the Different Colours of a Candle Flame?

There are three regions and colours of a candle.

Blue is at the bottom of the flame. This section is blue because it is oxygen-rich. It is oxygen-rich because it is where the hydrocarbon molecules begin to separate into hydrogen and carbon atoms.

Above the blue section is a dark orange-brown part of the flame. This region has little oxygen and is where carbon breaks down and begins to form into carbon particles.

The rest of the flame is yellow comprising of most of the flame’s colour.

The yellow part of the flame is most dominant and where the carbon particles ignite. Although the combustion process emits a wide spectrum of light, the human eye sees the flame as yellowish.
