Hurricane Candle Holders. Typhoon lamps are basically a great enclosure around the light in order to avoid it from going out inside the wind. Initially candles were used in hurricane lamps, but gas was found to be much easier to use. Today candle storm candle lights are firmly decorative and ornamental. The quake candle holder has a starting with a removable glass face shield around it. This give protection to is open at the top. The glass can be a simple tube shape, but is more likely for being shaped artistically with a lamp at the bottom narrowing to the leading. The glass can be clear or decorated with habits or frosting. There is another kind of hurricane candle, where dried up flowers, leaves or shells are placed in the wax. The candle is meant to burn up down leaving the outside unmarked. Then the hurricane candle may be lit up using a tea light to show the design still left in the wax shell. In some cases the candle is perfumed.
