Using Fragrances and Dyes Wisely

When it comes to candle making, adding fragrances and dyes to your candles can enhance their aesthetic appeal and create a pleasant atmosphere when they are burning. However, it is important to use these elements wisely in order to prevent tunneling in your candles.

Tunneling occurs when the wax burns down the center of the candle, leaving a thick ring of unburned wax around the edge. This not only affects the appearance of the candle but also diminishes its burn time.

To prevent tunneling in candle making, it is crucial to carefully measure and add fragrances and dyes to your wax. Excessive use of fragrance oils or dyes can negatively impact the way the wax burns, leading to uneven melting and tunneling.

It is recommended to follow the guidelines provided by the manufacturer of the fragrance oil or dye regarding how much should be used per pound of wax. Additionally, consider using fragrance oils that are specifically designed for candle making as they are formulated to work well with different types of waxes.



Another tip for preventing tunneling when using fragrances and dyes in candle making is to ensure that they are thoroughly mixed into the wax. Incomplete mixing can lead to uneven distribution of fragrances and dyes, which may result in uneven burning and tunneling. Take your time when blending in these elements into the melted wax, making sure that they are fully incorporated before pouring the mixture into your candle containers.

Properly incorporating fragrances and dyes into your candle-making process can significantly contribute to preventing tunneling issues in your finished products. By following these guidelines, you can enjoy beautifully scented and colored candles without compromising their burn quality.
