Paraffin candles are made from a byproduct of petroleum refining. They are popular for their affordability and wide availability. These candles burn cleanly and produce a bright, steady flame, making them a common choice for home lighting and decoration. In addition to their aesthetic appeal, paraffin candles can be scented or colored, enhancing their use in creating ambiance. However, some people prefer alternatives like soy candles or beeswax candles due to concerns about the environmental impact of paraffin, which is a non-renewable resource.
