Abstract
A flame-retardant wick holder for a candle is made of a plastic having a UL-94 vertical burn test rating of at least V-0. The wick holder has a bore for holding a wick at the bottom of a candle. The wick holder is provided so that when the candle and wick burn down to the level of the wick holder, the material of the wick holder causes the flame on the wick to extinguish, thereby preventing flashover of the residual candle fuel at the end of the candle useful life. The wick holder is preferably made of a polyethersulfone (PES).
