No matter how skilled you are in candle making, colouring-changing lights can add a whole new level of excitement to your craft. Whether you're looking to impress a friend with a homemade gift, decorate your home with a splash of colour or just try something new, this craft will leave you with a sense of satisfaction and style.
Gather your candle jar, light-emitting diode (LED) and hot glue gun. Colouring-changing LEDs come with a wick attached to them, and this is what you want to attach to the centre of your jar. Carefully attach the LED wick as close to the centre of the jar as you can get with your hot glue gun. Slide it over the wick with a straw and press down firmly until the glue is dry.
Weigh out the amount of wax you need for your candle. This is usually 29 g (1 oz) less than the jar you're using. For example, if your candle jar is 227 g (8 0z) you should use 198 g (7 oz) of wax.
Heat the wax in a double boiler to 82.2 degrees Celsius (180 degrees Fahrenheit). Once the wax is completely melted, add any desired fragrance and stir. The amount of fragrance you add depends on how strongly you want your candle to smell, but 28.4 g (1 oz) per 453 g (1 lb) of wax is considered average.
Cool down the wax to 65.6 degrees Celsius (150 degrees Fahrenheit).
Pour the melted wax into the candle jars slowly, keeping the straw in place. This will ensure that the wick stands up straight and doesn't get lost in the wax.
Remove the straw from the wick after you've poured the wax, but before it has time to set. Make sure that the wick is still in the centre of the jar.
Place the candle somewhere to cool. This process can take several hours depending on the size of your candle jar and works best if left to cool overnight.
Trim the wick of your candle to the desired length. This should be no more than 1.2 cm (1/2 inch) to prevent the flame from jumping and starting a fire.
Light your candle. Colouring-changing LED wicks require no extra care, no batteries and no switch. Simply light your candle and watch the colours change.
If your candle dries with bubbles on the top, you can smooth these out by using a hair dryer or a heat gun.
Always heat wax to the proper temperature. If the wax too hot, it can burst into flames.
