Paraffin candles are made from a byproduct of petroleum refining. They are popular for their affordability and ability to hold fragrance well, making them a common choice for home decor and aromatherapy. When burned, paraffin candles produce a bright, steady flame and can come in various shapes, sizes, and colors. While paraffin candles are widely used, they can release small amounts of soot and other chemicals when burned. This has led some consumers to seek alternatives, such as soy candles or beeswax candles, which are often considered more environmentally friendly and may produce less smoke.
