Wax tarts are made to be melted in either an electric tart warmer or a tart warmer heated by a tealight candle. When the scented wax melts it releases the fragrance into the air. We have a wide selection of scented wax tarts for you to choose from. We make soy tarts in a convenient clamshell packaging. If you have a tart burner you can also use it to melt left over wax from other candles such as scented pillars.
