In my recent candle making class, one of the hobbyist asked me if she can use crayons for coloring candles.
Well if you want to want to make great candles then the answer is NO. Though it may seem that crayons are colored wax so why not use them to color the wax. Its the pigments with which the crayons are colored that are insoluble. They don't dissolve in the wax. They simply float and it may seem that they have colored the wax. As a result of this the pigments get centered around the wick and clogs it. While burning the candle these pigments inhibit the fuel(melted wax) to reach the wick and your candle may not burn properly.
So definitely, coloring wax with crayons for candle making is a NO NO. Always use the candle making dye only to make great candles.
