Other – Ceramic Light Bulb Ring
These work great!
Place on top of incandescent light bulb, or radiator, after adding 4 to 8 drops of pure essential oil.
Washes out easily to re-use with a new scent.
(Unglazed rings will hold the scent of previous oils, which may not be desirable.)
Do not overfill. Essential oils are potent, and a little goes a long way.
