A candle is a solid block or cylinder of wax with an embedded wick, which is lit to provide light, and sometimes heat. Today, most candles are made from paraffin.
Candles can also be made from beeswax, soy, other plant waxes, and tallow (a by-product of beef-fat rendering). Gel candles are made from a mixture of paraffin and plastic.
