Abstract
A flame-retardant wick holder for a candle is made of a material having a UL-94 vertical burn test rating of at least V-0, including polymers and ceramics. The wick holder supports a wick at the bottom of a candle. The wick holder material causes the flame on the wick to extinguish when it reaches the holder, thereby preventing flashover of the residual candle fuel at the end of the candle useful life. One version of the holder has a cylindrical sleeve fit over a wick clip holding the lower end of the wick. The cylindrical holder is well adapted for use in pillar-type candles.
