Paraffin wax is the traditional wax for candle making and is still by far the most popular wax. It is good for beginners because it melts quickly, is cheap and is easily colored or scented. However, note that the chemicals that are emitted when this wax is melted could be irritating to some people. [3] X Research source One pound of paraffin wax by weight will equal approximately 20 oz of liquid melted wax. Soy wax is becoming increasingly popular as it is easy to use, made from soybeans and cleans up pretty easily. It is eco-friendly and renewable. Soy wax is also known to burn more slowly than most other waxes. [4] X Research source One pound of soy wax will equal approximately 18 oz of liquid when melted. Beeswax is all natural and has air purifying qualities to it; however, it doesn’t retain scent or coloring that well. Essential oils will generally work with beeswax but keep in mind that beeswax has its own lovely scent.

Melt paraffin wax until it reaches between 122–140 °F (50–60 °C). [7] X Research source Melt soy wax until it reaches between 170–180 °F (77–82 °C). [8] X Research source Melt beeswax until it reaches roughly 66 °F (19 °C). [9] X Research source Melt old candles at around 185 degrees (85°C). [10] X Research source Remove the old wicks with tongs.

If you have a particularly wide container, dangle multiple, evenly spaced wicks into the container.

Keep in mind that beeswax will shrink a bit after cooling, so you may need to pour more beeswax to account for any gaps in the mold.

Add citronella to your wax to make your candle a natural insect repellant. Before adding an essential oil to your candle, make sure you double-check that the oil in question is safe to be used in candle-making.
