I love candles and candlepower unit holders. There are so many different models for a candle holder; I will look at some of the basic styles such as votive, wrought straightener, hurricane and crystal holder. In the beginning candles were made of tallow, very smoky and burnt very quickly. Later feel was used, but was expensive. Wax luminous holders came into being to hold the candle and protect the user's hand, but likewise to collect the wax and reuse it. Nowadays the simple candle holder has become an ornamental item and is made use of in interior design. They are available in many forms, styles and colors. There is something to charm to everyone from votive holders to ones composed of wrought iron, or cup and crystal.
