Beeswax is solid at room temperature but melts easily and burns slowly, producing very little smoke and emitting a sweet smell. These qualities make it ideal for candle-making although whether or not it is the best material remains subjective. Early candles were made from tallow, processe from animal fat. Tallow candles smelled unpleasant and burned quickly, so beeswax offered big benefits over these. Nowadays, there are many alternatives to beeswax. Most candles are made from paraffin wax, which is odourless, clean and cheap, but other materials such as soybean wax are also popular.
