Good question. I would like to get an answer from Aspire, but they are still refusing to provide that information. They even pulled the old answers about the mystery ceramic/fiberglass material from their website--it used to be here and now it's gone:
Aspire Support: View topic - bvc wicking material
Per most reviewers, including Rip and Phil, it's the same fiber. It crumbles and it burns, also. Go to 14 min mark into the video:
Exactly right--I want more facts, but I can't get them. I've sent several emails to Aspire asking for answers.
And now it turns out that their tanks are not stainless steel as advertised. The chimneys are made out of chromed brass.

On the subject of fiberglass:
http://srs.unm.edu/industrial-hygiene/media/docs/silica.pdf
"Amorphous Silica: Multiple studies have found amorphous silica to be biologically inert when
ingested and inhaled, with the exception of extruded fiberglass and ceramic fibers (which have been
designated as carcinogens by the National Toxicology Program), which are hazardous due to their
very small size and their high length to width aspect ratio.
Because of this inertness, the US Food
and Drug Administration permits the use of amorphous silica (not fiberglass or ceramic fibers!) in food and medicine."
So, I'd rather stick with amorphous silica and organic cotton in my atties than risk inhaling fiberglass particles. You may of course disagree with my opinion. Please feel free to do so. This forum is--and has always been--about exchanging information. I hope it will remain so.
Just because you're paranoid, doesn't mean they are not after you.
