sometimes the dye will interfere with the wick
perhaps the dye slows the wax from melting as fast
White candles tend to burn at a slightly quicker rate than colored candles due to differences in the dye and other additives used in colored candles. These additional substances can affect the burning speed of the candle.
dye dye
The main ingredients in a white candle are wax (typically paraffin or soy), a wick, and a fragrance or dye (if added for scented or colored candles). White candles do not usually contain any additional colorants or fragrances to maintain their pure white color.
A white candles has no color added to it. Colored Candles have colors added. When you make a Colored Candle you used a Dye Block, dye chips or a liquid color used to color candles with. An all white candle is just the wax itself without color added to the Candle. Colors used to Color candles can be found online by searching for a Candle Supplier. There are also Ivory Colored Candles as well that looks white but sometimes colored can be added to a white candle by using an Ivory Color for your Candle.
The dye depends strictly on the color.
The color of a candle is determined by the dye or pigment added to the wax. The burning rate of a candle is primarily influenced by the composition of the wax and the size of the wick. White candles typically use a purer form of wax, such as paraffin, which has a higher melting point and can burn more efficiently than colored candles that may contain additional additives. Additionally, the dye or pigment in colored candles can affect the combustion process, potentially slowing down the burn rate compared to a white candle.
Colored candles can burn faster than white candles due to the impurities present in the pigments used to color them. These impurities can affect the combustion process, making the colored candles burn at a quicker rate. Additionally, the composition of the wax and the amount of dye used can also contribute to the difference in burning speed between colored and white candles.
White candles. The colour of the candle doesn't matter, only the dye in the wax only has a change of seconds. The only properties that really matter are the composition or type of wax (paraffyn, beeswax, plant waxes,...), also its thickness and lenght.
Colored candles typically contain synthetic dyes or pigments that are added to the wax during the manufacturing process to create the desired color. These dyes are specifically formulated to be safe for burning and won't produce harmful fumes when the candle is lit.
White candles reflect the light in the experiment.
