A glass oil burner typically consists of a base or dish to hold the oil, a holder for a tea light candle, and a glass or ceramic top with a hole or opening. The purpose of the hole or opening is to allow the heat from the candle to warm the oil and release the fragrance.
If you use a glass oil burner without the hole in the top, it will significantly affect its functionality. Without the opening, the heat from the candle will be trapped inside the burner, preventing it from properly warming the oil and releasing the fragrance into the air. As a result, the burner may not provide the desired scent dispersion, and you may not experience the intended aromatherapy or fragrance effects.
Additionally, altering the design of the oil burner by covering or sealing the hole could create safety concerns. The heat generated by the candle needs proper ventilation to dissipate and prevent overheating. Blocking the hole may cause excessive heat buildup, potentially leading to the glass or ceramic material cracking or breaking.
It's best to use a glass oil burner as intended, with the hole in the top, to ensure proper functioning and safety. If you're looking for alternative ways to fragrance a space without the use of an oil burner, consider using diffusers, reed diffusers, or other suitable fragrance devices specifically designed for that purpose.
