The coloring and fragrance of a candle can make it stand out and tranform the look immensly. Color and scent can help you customize your candle for your specific customers. Color and scent if used incorrectly can also cause your candle to have other problems like not burning.
When coloring a candle it is best to start off with less color, you can always add more later if the color isn’t dark enough. The main three forms of candle color are liquid, color block and diamond dyes. The liquid color comes in liquid form making it easy to measure, it can stain if it gets on clothing, skin or other surfaces. Color blocks are a small block of color that you can shave or cut off pieces to add to your wax. Color blocks are the cheapest color method but measuring the amount you add is more difficult. If you want to go back and use that same color again it will be more difficult to shave off and use the exact same amount. Diamond dyes are similar to color blocks but they are pre-measured into small diamond shapes. The pre-measured shapes make it easy for you to get the same color again unlike the color blocks without the potential mess of liquid dyes.
A tip for testing color before pouring the candle is to put a few drops on a white piece of paper and wait for it to dry. Once the wax is dry you can then decide if you would like to add more dye to darken the color. Keep in mind the candle when poured may be appear slightly darker then on the paper because it is not on the contrasting white background. Be careful not to over add color, if too much color is added to the candle it can clog the wick causing the candle not to burn.
The basic rule for scenting a candle is to use 1 ounce of fragrance oil per 1 pound of wax. Some waxes can hold more scent then others, it is important to check with your supplier. Make sure you are measuring your wax and scent by weight using a scale. Different fragrance oils weigh different amounts, why measuring by weight is so important. If too much fragrance oil is added it could cause the candle to not burn or the scent could leak out of the candle. The quality of the fragrance oil can make a big difference on how the candle burns and its cold and hot throw.
Using different scent and color combinations can allow you to get very creative with your candles giving them a unique touch!
