These canning jars are filled with highly absorbent crystals, color and fragrance. Open the lid and leave open in a small sized room, and the fragrance will freshen the room. As the water evaporates from the crystals, fragrance will be released into the air. Eventually, there will only be hard crystals and fragrance oil in the bottom. Then the jar can be recharged by refilling the jar with distilled water. Each fragrance will behave differently, but the jar should last several cycles of dehydrating and rehydrating.
Perfect for car cup holders, bathrooms, nurseries, kitchen, classroom, office, or anywhere you could use a beautiful scent, but don't want the hassle of a flame or don't have access to electricity. This can even be used in a potpourri warmer for a stronger throw by adding just a small scoop to the warmer or place near another heat source.
