Wax tarts are pieces of highly scented wax that are placed in tart burner/warmer.
Burners/warmers can be powered by electric or tealights. There are also jar warmers available that are
used to melt candles/wax in jars. You put the tarts in the bowl, jar or dish, light the tealight or turn on the warmer
and the melted tarts produce a delicious aroma
in your home or office without the danger of an open flame of a candle.
