Science Behind Candles

What is the science behind candles? Well, let’s start with the basics of how candles are made. Candles are formed by using wicks dipped in either paraffin or beeswax, which can mix with other ingredients to enhance various qualities of the candle, like scent or color. There are three main steps to making candles: pouring the melted wax into molds and letting it cool.

We'll discuss about:

The Basics of Candles

Candles are fascinating! There are so many different types and colors that it can be hard to pick just one. But it’s always fun to learn a little bit about the scent or story behind a candle. For example, the bubbles in a scented candle are caused by a process called cavitation. Carbon dioxide gas bubbles when heat liquid is poured into the wax and more liquid add.


As these bubbles rise and bump into each other. They cause an intense vibration called cavitation that sends high-pressure sound waves through the fluid in what looks like an explosion of tiny bubbles. These bubbles then heat the liquid around them, which causes even more bubbles to form and repeat the process.

How does a candle work scientifically?

A candle is nothing more than a source of fuel (usually wax or grease). And a wick with a container to hold it. The item becomes lit by providing heat from a lighter, match. Or another flame from an existing candle. Which melts the wax or fuel and recasts it onto the surface of the wick.

As heat travels up through these materials, water inside them vaporizes, melting more wax; meanwhile, as they heat up, they expand and vaporize a small portion of hydrocarbons along with oxygen dissolved in them. These vapors then ignite when reaching an ignition temperature; it is a good work of science.

What type of science are candles?

We talked about how everything on Earth comprises atoms and their different ratios. It’s a similar story for candle making. The wax starts as an organic material, which, when heated, becomes a liquid at about 120°F. Then, to get the desired waxy consistency. They mix this molten liquid with additional organic materials like shea butter, coconut oil, beeswax, or soybean oil.

As soon as it reaches its melting point-which can be anywhere from 180-210°F depending on what kind of wax you’re using you. You can pour it into moulds or shape it by hand into balls or whatever other shapes you want your candle to take.


Final Words

Candlemaking is not only an art form but also has a lot to do with chemistry. Beeswax burns without a flame and smells excellent in all types of candles- solid pillars, votives, jarred candles for the bath, or aromatherapy. There are also plenty of additives that you can use, like soy wax. And essential oils, that can bring some pleasant scents to your home.

You might also like to mix them up now and then, so you don’t get too accustom to one scent-a safety precaution if you’re allergic to certain scents! Finally, it’s always important to track how much time you’ve burned your candle each time you light it. How long should a candle burn before being put out? That depends on what type of candle it is and how big it is. But usually, somewhere between two and three hours would be appropriate. That’s enough time to create a relaxing atmosphere at home!
