A candle warmer is an electric warmer that melts a candle or scented wax to release its scent. The candle warmer shown is intended to be used with jar candles or candles in cups, not with taper candles or candles without containers large enough to accommodate all the melted wax. Some candle warmers have a built-in bowl in which the candle is placed.
The advantages of using a candle warmer include the absence of open flame and the soot that often results from burning wax. The main disadvantage of a plate candle warmer is candle life. While the candle can still be burned (provided the wick is still exposed), the wax no longer contains any fragrances. Many warmers are designed to be used with "wickless" candles, which are blocks or lumps of scented candle wax with no wick.
