Safety of glass jar candles after use

Cooling: After the candle is extinguished, allow the jar and wax to cool completely (usually 2-3 hours) before cleaning or storing.
Wax Residue Removal: If you wish to reuse the jar, wait for the wax to solidify before refrigerating it for 10 minutes. This will allow the wax to shrink and separate from the jar wall, making it easy to remove. Do not rinse the hot jar directly with hot water.
Disposal: After the candle is used, clean the cooled jar (remove any remaining wick and wax residue) and recycle or store it as a standard glass product to avoid fire hazards caused by residual wax.
