A votive candle or prayer candle is a small candle, typically white or beeswax yellow, intended to be burnt as a votive offering in a religious ceremony. It now also refers to a standard size of candle two inches high by one and a half inches diameter, of any color or scent.
Votive candles are made from paraffin or wax, but there are different grades of paraffin with different melting points. Often paraffin is mixed with other types of waxes like beeswax or vegetable wax. This is done to obtain the rigidity necessary for the type of candle being made. Depending on the quality of wax used, a candle may burn very fast or very slow. It may have a low melting point and produce little to no oil, such as a taper candle that sits in a candle holder “ring,” or it may have a very low melting point and turn to oil, as with votives that sit in glass cups. Pillar candles, large candles often with multiple wicks, have their own formula. Candle quality also varies widely depending on the candle maker. The aroma from a lighted scented candle is released through the evaporation of the fragrance from the hot wax pool and from the solid candle itself. It’s highly unlikely that you would find a lead wick in any candle sold in the U.S. today. Lead-core wicks have been banned from the U.S. since 2003, and members of the National Candle Association – which account for more than 90% of candles made in the U.S. – have not used lead wicks for more than 30 years. Reputable manufacturers use cotton, cotton-paper, zinc-core or tin-core wicks, all of which are known to be safe.
