These cast iron cauldrons are filled with your choice of soy candle scent. When finished burning, simply rinse out remaining soy with warm water and dry thoroughly to prevent rusting. The cauldron can then be used to burn loose herbs for smudging, use as a planter, or simply keep as decoration. This cauldron comes with a plantable candle duster filled with wild flower seeds. Herbs, flowers, crystals will vary depending on scent chosen. Approx 4 oz.
