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.

Beeswax candles grew in popularity very quickly. These produced less smoke, gave off a pleasant scent, burnt for longer periods of time and did not drip. In those times, candles were not for used by the common man, as they were very expensive and they were considered a luxury item.

Blended wax candles burn slowly as compared to plain wax candles. Today candles are available in a wide variety of sizes, shapes and styles. These include votive, tapered, round and scented types. Nowadays, people even use soy and vegetable candles. In the past, candles were always handmade, but these days, outside of specialty shops, most candles are machine made.

Candles are no longer used as the sole source of light. They are now used for their visual effects and decorative purposes. They are also used on religious occasions, for lighting altars. They are also used as emergency lighting, in case of electrical failures. And, of course, most common modern use for candles is on birthday cakes.
