Candle Science Candle Making


Candle making is a science and an art. The science of candle making comes from understanding the nature of wax, heat sources, and wicks. Wax is composed of hydrocarbons which burn when heat is applied in the presence of oxygen. Different types of wax have varied degrees of melt points, combustion temperatures, and fragrances that affect the burning characteristics of a candle. Heat sources can be flame (such as a lighter or match), an externally heated element like an electric candle warmer, or internal heating from electricity through electronic components. Wicks are made from materials such as cotton fibers intended to draw liquid wax up into the material where it fuels the flame for burning.

When you combine these three elements – wax, heat source and wick – you have the science behind successful candle making! The art behind candle making manifests itself in different shapes, colors, and scents that come together to make your candles truly unique works of art. Plus, once your candles are finished you get to enjoy their romantic glow to enhance any room!

Chemistry of Candle Making

Candle science is a fascinating topic, and candle making is an activity that draws from many different sciences. The chemistry of candle making involves a wide variety of chemical reactions, both physical and chemical.

One particular reaction that plays an important role in the creation of candles is combustion. This process relies on oxygen from the air to fuel the flame that heats up the wax and causes it to melt into liquid form. The heat release from this reaction is what gives off most of the light emitted by burning candles.

Another reaction necessary for candle production is polymerization, which allows wax molecules to combine with each other and form long chains. This ensures a superior quality candle with increased strength and stability, as well as helping to give it a longer life span.

Finally, vaporization plays a major role in candle making by allowing volatile compounds such as scents to be released into the atmosphere when the wax starts melting. Volatiles are created through heating large particles made up of smaller molecules until they become free-floating gasses which can ultimately enhance your overall experience while burning your candles.


Candle science candle making is a fun and rewarding hobby that can be easily customized to create beautiful, unique candles. There are several ways to make candles more sustainable or environment friendly. One approach is to use beeswax instead of paraffin wax, as it is a natural, renewable resource that does not contribute to toxins found in traditional paraffin wax (which is petroleum derived). To reduce the amount of energy used during the process, consider using eco-friendly wicks made from cotton core or bamboo. Soy wax can also be used instead of paraffin and is biodegradable and non-toxic, making it a great alternative for those looking for an even cleaner burn. Additionally, sustainably-sourced fragrances should be chosen to ensure the ingredients were farmed or harvested responsibly with minimal negative impact on the environment. Finally, consider reusing containers or buying vintage containers for extra eco-friendly points!

The Tools of Candle Making

Candle making involves many different pieces of equipment. The most essential is a double boiler set, which typically comes with two pots, one to fit over the other. This is used to melt wax and keep it at the necessary temperature while creating candles. Another useful tool is a thermometer designed for candle use, as this helps ensure that the wax reaches the right temperature without overheating or burning it. For beginners, kit pre-measured supplies are important tools in producing batches of candles consistently without guessing amounts of colors and scents. In order to create interesting shapes and multi-layered designs, having molds made from metals, plastic and silicone will be necessary. Lastly, wicks are also required in order to ignite and burn your candle properly. Most come with tabs attached at the bottom so that they can be placed securely into waxed containers or molds.

Varieties of Candle Making

Candle making is a craft that can take many forms. Here are just a few of the different types of candle making:

At Home Candles

1. Container Candle Making: This method involves using glass containers and pouring hot wax directly into them. This is often used when creating more intricate designs in the candles.

2. Pillar Candle Making: This form of candle making requires special molds which are then filled with melted wax and scents to create a pillar shaped candle.

3. Gel Candle Making: Making gel candles requires immersing fiberglass wick in specially formulated gel, leaving it to harden before adding fragrance, glitter or decorative elements to complete.

4. Melt & Pour Candle Making: Using pre-made blocks of glycerin and/or paraffin wax, these blocks are heated in a double boiler until totally melted so any desired scent or color can be added to create homemade candles quickly and easily .

Troubleshooting Tips

Candle making is an enjoyable hobby, with the potential to create beautiful and aromatic products. However, there can be a few bumps along the way for beginners before they achieve success. Here are a few tips to help you troubleshoot some of the more common candle making issues:

1. The Wick is Too Short: To ensure that your wick is the correct size for your specific vessel, measure it as close to the top of your wax as possible. Make sure it’s at least 10cm in length so that it will be able to catch fire and stay lit contained within the wax.

2. The Candle Won’t Stay Lit: If a candle won’t stay lit, chances are there isn’t enough oxygen getting into the wax around the flame. Try trimming back any “wax snakes” that could be disrupting oxygen flow or making contact with and possibly extinguishing the flame. Additionally, make sure your wick size matches the circumference of your glass or container to better provide ventilation and decreased potential contact with other materials like walls or collections of wax snakes on top of your poured wax.

3. Fragrance Problems: Strong scented candles often require extra oil than regular candles – almost twice as much! Some fragrances blend better than others which should be noted when experimenting with different combinations; mixing too many fragrances can result in smell confusion and ultimately not give off an aroma you expect from using either scent individually. Also check if fragrance mixes have been adjusted for colour when adding additives like dye chips – unsaturated colours won’t necessarily enhance your candle scent but can lighten any perceived fragrance strength in general (especially when used in large quantities). Finally, try sticking to brands made especially for soy candle scents as these generally carry outstanding quality control measures compared with generic formulas bought online or from craft stores directly.

Candle Making Recipes

Candle making is a fun and creative craft that can be enjoyed by beginners and experts alike. Candle science, or the study of how materials interact when set aflame, is perhaps the most important element to consider when crafting your own candles. By understanding how various types of waxes and wicks burn differently, you’ll be able to create beautiful and unique candles with fascinating effects.

The first step in creating your own unique candles is to determine which type of candle you would like to make. Popular styles include pillars, tapers, tealights, floating candles, aromatherapy candles, jar candles, decorative mold candles and novelty shapes. Each style requires different ingredients which may include waxes such as paraffin or beeswax (or blends), natural or artificial fragrances, essential oils, wick tabs or metal wick sustainers and dyes/color pigment. Once you have determined the ingredients that will best suit the type of candle you’d like to make it’s time to start crafting.

When making a candle the most important principle is understanding melting points for different wax types so an accurate mixture of wax and other materials is achieved for optimal burning results. Once melted it’s recommended that temperatures are monitored using a thermometer as extreme heat may cause discoloration or weakening of container walls/wick holders. Adding scents/dyes should occur just before pouring into molds so fragrances retain their potency since fragrances can dissipate quickly at high temperatures. After pouring it’s essential the right size wood or metal base wick is selected that creates consistent flames that don’t flicker excessively (unless desired) over the life cycle of the candle. Finally once room temperature has been reached its crucial to trim off any loose wax at the top so an even burn can take place as many cosmetic imperfections will appear as they cool down completely otherwise

Creative Projects

Candle making can be a fun and rewarding hobby, but it’s also an excellent way to hone a variety of craft skills. Taking on any new project is always a challenge for both beginner and experienced crafters alike, so below are some ideas for candle science projects that will challenge and inspire you!

1. Create Unusual Candle Shapes: Try making your own candle molds by using everyday materials such as clay or dough, then experiment with different sizes and shapes to get the perfect fit. Once finished, you could even color your candles using paint or glitter for extra flair!

2. Learn About Different Waxes: Experiment with different types of waxes (such as paraffin or soy) to find out which ones are best suited to your particular needs. Consider how they melt, how much scenting each type can hold and make sure you’re happy with the final result before investing in any supplies.

3. Create Layered Candles: A unique way to show off your candle making skills is through creating candles with layers of embedded colors or scents. Start by melting down two different colors of wax separately, then pouring each one into a separate side of the same mold while they’re still hot enough to mix together slightly. After the wax hardens quickly move onto adding a third layer if desired and repeating until satisfied.

4. Make Scented Candles With Essential Oils: Rather than relying solely on store bought fragrances create beautiful handmade scented candles using essential oils instead. This is an excellent way to customize your candles and give them an aroma that fits in perfectly with the rest of your décor!

5. Create All-Natural Beeswax Candles: Beeswax not only makes beautiful ivory colored candles but it naturally has its own pleasing scent that no artificial fragrances can match! To make beeswax candles try combining melted beeswax with other all-natural ingredients such as coconut oil or Shea butter before adding your chosen aroma if desired (essential oil blend here!) Lastly finish off by adding cotton wicks for added stability as well as finishing touches like wooden pulls or pretty ribbons around the base if desired!


Candle making is an art and science that involves more than just throwing wax into a container, and requires careful consideration of the type of wax being used, the size and shape of the containers, as well as the fragrance, colors and dyes. The most important thing to keep in mind when making candles is safety: always make sure you’re following safety protocols for working with hot wax.

When all of these pieces come together properly in candle-making, it produces something incredibly unique. Candles become less about ordinary utility items and move closer to becoming personal works of art. These beautiful creations are often thoughtful gifts for those celebrating special occasions or life milestones, or simply to show a loved one how much they mean to you. By using your creativity while learning the fundamental principles involved in candle-making, candle makers find themselves unlocking new doors every time they sit down at their workbench.

Ultimately, one can recognize that there is both an art and science behind creating beautiful candles which can be appreciated for more than what meets the eye. Not only does candle-making take patient practice and dedication to perfecting each task from melting wax to styling wicks but also planning out ideas beforehand on paper or sketchbook as well as understanding why certain techniques work better than others.
