Interested in learning how to make your own candles? The candle form that I chose to experiment might surprise you. These flexible couplings can be found right in the plumbing aisle of a home improvement store, can be used repeatedly for your candle-making projects and are available in a variety of sizes (a 2″ wide model that I bought cost $4.33).
Prepare your double boiler system on your stovetop and begin to heat the wax flakes to 180 degrees Fahrenheit.
When the wax is 180 degrees Fahrenheit, turn off your stove and add fragrance oil (optional) and color (optional) and allow the wax to cool down to about 125 degrees Fahrenheit.
If you add the fragrance oil while the wax is still over the heat, you risk the scent evaporating away.
While the wax is cooling, prepare your forms. I experimented by using a round recyclable plastic container and the aforementioned rubber coupling from the plumbing aisle. To prep the rubber coupling, use a hot iron to fuse a piece of wax paper to the base of the coupling.
Allow the wax paper and rubber to cool. The seal should be apparent, and the wax paper should be completely adhered to the rubber.
Pour the melted wax into the forms (at temperature 125-degrees Fahrenheit). Keep a close eye for leaks in the base of the forms as your pour – if there are leaks, know that the wax will continue to pour out freely. With no leaks through the wax/rubber connection, I considered this method a big success!
Watch for the wax at the base of the candle to begin to cool (you may be able to see it becoming more opaque in this photo). Drop the wick tab and rope into the candle, and center it. Center the rope as it emerges at the top of the candle, and brace the rope in place so that it doesn’t shift as it cools (I used a spatula that wouldn’t be inclined to roll).
Allow the wax to dry overnight (24 hours is recommended, but consider shorter or longer depending on the diameter of your candle). Keep in mind that if you’re using a rubber coupling, it will likely insulate the heat and take longer to cool than if you tried this method in a thin plastic container.
Both methods that I attempted popped loose easily from the forms. The candle slid out of the plastic recycled container like an ice cube from an ice cube tray, and the other attempt with the rubber coupling loosened easily like a push pop once the wax paper on the base was peeled free (and it will just peel free — so easy!).
For a pillar using a plastic container form without tapered edges, you might want to try using a cake frosting container!
