its what causes atomizers not to last long thow.. the coil rarely fails.. we think the wick is just wick.. not heat resistant silica gel..
u are assuming way to much with these things.. ultrasonics.. burn proof wicks.. u are way off.. they are cruder than u think they are.. stop assuming and start taking a few more apart.. u might know then and not have to "assume"..
Just because the wick gets dirty as hell doesn't mean it is the wick that burns. I'm not too keen on ruining a perfectly good atomizer just to test if that wick burns at 1000C or whatever. Besides, I could definitelly use ultrasonics or silica fibers if I wanted to. Heck, you can buy ultrasonic nebulizer for $30.
Many, many, MANY failed atomizers have been dissected and the fibers in the coil have been burned to ash. There are photos on this and other forums.
I just got my Ruyan Disposable Cigar today. It tastes as good as it looks...very yummy.
