How to put crystals in candles? Guide

If you would like to incorporate some crystals into your candle designs you can follow the guide below.

You will need: 

Decide the crystal 

The first step is to decide the crystal to add to your candle. After deciding, select and keep the gem in a container close to you so that you don’t have to stress yourself later on. Bear in mind the following when choosing your crystal: 

  • Polished and smooth gems are the best. Although crystals are hard and strong, you will cover them in wax. As a result, you need the type that won’t fill with wax during use. Therefore, choose gems without cracks and crevices. 
  • Any size will work as long as it fits inside the candle. If you want, you can crush a large gem into smaller bits so that you can put a lot into your candle. 
  • Avoid crystals that are sensitive to heat. For example, citrine will fade when you heat it. Opal also contains water; hence, it will fracture when you heat it. Items like coral, pearls, and coral will also react badly to heat. Avoid any material with an organic origin or artificial gemstone. 

After deciding the type of crystal that you want to use, head over to your local stores or make a purchase online.

Prepare the container 

Put your wicks inside the prepared container and use a pencil or clothespin to fix the wick at the center of the container. Cut the wick and make sure it is a bit longer than the height of the container – a few inches more will do. Tie one end of the wick to a pencil, popsicle stick, or chopstick, and balance the other across the lip of the container. 

Melt the wax 

Measure the quantity of wax you will need to make your candle. Then, melt the wax. To melt your wax, you can use different methods. For example, you can boil water in a stainless steel mixing bowl and put another bowl with wax on top of it. Alternatively, you can use a microwave-safe bowl and microwave the wax until it is liquid. 

A few things to note while you melt the wax: 

  • Use heat pads when you are handling the bowl to protect yourself from hot water. That said, don’t ever use your bare hands throughout the procedure. Use gloves.  
  • Use heat-resistant materials, not plastic. Don’t use plastic for any of the processes. 

After melting the wax, let it cool for a little bit, then add essential oils. You can use a blend of essential oils to make your favorite scent. However, be careful to avoid an allergic reaction. In other words, don’t use essential oil that triggers an adverse medical reaction. After adding oil, stir it repeatedly to spread it evenly. 

Pour the molten wax into the candle holder 

Slowly and steadily pour the wax into the candle holder. Be careful to keep the wick upright during this process. Wait for the wax to harden a bit and add your crystals. 

You can set crystals in your candle in stages or layers or simply add them as a topping. If you prefer the earlier, pour candle wax in layers and add crystals between each layer. After each layer cools, place one or more crystals on the hardened surface, and repeat the process till you are satisfied. 

Alternatively, you can just wait till the entire wax hardens and add your gems on the surface. Melt the remaining wax and pour it over the gem. Fill the container to the required level, but keep the tip of the wick visible. At this stage, your crystal will be invisible – buried beneath layers of wax, but the tip of the wick will be visible. 

Trim your wick 

When the candle wick is too long, the flame will be too high. It also causes different candle problems. Therefore, trim the wick to about ¼-inches in length.

How do you clean your crystal after your candle is finished? 

As we mentioned, you can reuse your crystal. After the candle burns out, clean your crystal with warm soapy water to remove excess wax residue. Do note, though, that some stones are not fit for cleaning with water. For example, Angelite, calcite, red coral, azurite, and moonstone, etc.
