Its fine, and sorry, I read my response again and it came off real d-baggy (not my intention). What do you use for wicks? I use mainly cotton (balls and yarn) but have tried pretty much everything besides ceramic rods and ss mesh. I find you need to change them a lot more frequently because the taste will go bad quicker but I feel they preform better and are cheaper than anything else I have tried.
No worries at all.
The context was mentioned in another reply. The customer was a silica user that asked the clerk why he should consider cotton. The clerk absolutely did not mean "as safe" as the other materials you mentioned. As per the article, he said, "much safer than silica." I don't see how that could be interpreted to mean "as safe as silica."
