- Candles
The use of candles dates back to around 400 B.C. The first beeswax candles appeared during the middle ages; prior to that, candles were made of fat obtained from slaughtered animals. Now, candles are made of everything from animal fat to plant cells to synthetic materials, as well as a number of manufactured and organic scents and colorings to really personalize the type of candle you buy. You can even make your own. The purpose of these candles was solely to provide light. However, they were oily, had an unpleasant smell and emitted thick smoke.
