Tart burners are used to burn wax and generate pleasing aromas throughout a living space. They are often used in lieu of traditional candles. Both candles and tart burners melt wax to send off fragrance--although the burners have a much different design. Wax is placed in the top dish of a burner and a small tea light candle is placed underneath. Igniting the tea light wick sends heat directly under the dish containing the wax. The wax is thus melted and fragrance is emitted.
Cut four metal rods to 5.5 inches in length using a metal saw. Rods can be brass, copper or stainless steel. Cut a metal plate into a 4-by-4-inch square. The plate material should be the same as the rods.
Put on a soldering mask and protective gloves. Place the bottom of a metal rod flush on one of the corners of the metal plate. Turn on your soldering iron. A gas or battery soldering iron is preferable for easy maneuvering. Solder the rod to the plate. The process should take two to three seconds. Solder the other rods into the other three corners.
Fit a 4-by-4-inch metal dish in between the tops of the metal rods. The dish should be 1 to 1.5 inches deep so it can hold a wax tart. The dish can be brass, copper or stainless steel. Solder the rods to the sides of the dish. The tops of the rods should be even with the top lip of the dish.
Insert a wax tart into the dish. Place a tea light underneath it on top of the metal plate. Ignite the tea light.
Soldering irons produce a flame between 300 and 700 degrees Fahrenheit. Use extreme caution when working with one.
