Yes! Since the oil inside is UNCUT, it solidifies quickly and must be warmed to keep everything towards the bottom of the cartridge. The double-click preheat function on your battery is very important. Colder weather may call for other heat sources like a heat gun, small flame, heater, or other source of warm air. This cartridge is made of 100% quartz and is built to withstand high heat. Make sure you LET THE MOUTHPIECE COOL after heating your cartridge.
NOTE: There is little to no maintenance required if you keep the cartridge UPRIGHT as much as possible. Keeping the oil at the bottom on the cartridge and not letting it solidify while it’s laying down on it’s side is the easiest way to maintain your cartridge.
Can you refill the cartridge?
Yes! This is an extremely high quality cartridge that does not need to be tossed out once it is done. It can easily be refilled and used again with any type of wax.
