The purpose of a lantern is to release as much light from the candle as possible and to protect the candle’s flame from the wind. Glass is therefore the ideal material for candle lantern holders and it should be kept clean. A quick wipe with a damp cloth is usually sufficient. If there is a build up of wax, then warm soapy water will do the trick.
These candle lantern holders are designed for a single candle or tea light. They can also be used by larger candles, up to 4cm diameter and up to 7cm tall. The removable candle holder is raised up slightly which prevents the base from getting too hot, but care should still be taken.
