I am curious about the type of ceramic used in the cups of these atomizers. Does anyone know what material it is? I ask because I'd like to try one, and I can't afford a GG. That means a china clone, and I'm just not 100% about faith in Chinese standards. I've moved to steel hardware and cotton wicks in an effort to contain my exposure to crappy or dangerous materials as much as possible. I know i sound like a paranoid weirdo, lol. Anyhow, I'm just curious if anybody has any information about this material. Thanks!
