Hi Dave, let us know when you finish
I'm surprised that the powers that be haven't already picked apart everything that's contained in vaping products and tested them six ways to Sunday. We had that one little cursory test in 2009 by the FDA and they found 8ng/dl traces of carcinogens in an Njoy or Smoking Everywhere sample and a trace of diethylene glycol in a spectrographic test. Their control test was one done on a Nicotrol inhaler, which had the same amount of nitrosamines.
Depending on who you read, silica is very bad or not so much. If the fibers don't break down and pass into the lungs, it seems to be a moot point. You can rub the wicks on a Vivi head and pull off 1/2" to 3/4" fibers when it's dry. IF you want a rope to be stronger with more cohesive fibers, wet it down.
It's just my own hunch, but the wetting effect of juice on a wick should hold down most of the fiber shedding. I don't know that for sure, but it makes sense to me. Add to that the fact that the coil is wrapped around the part that air passes through and it captures the long strands. I may be completely off base and I'll admit that I'd feel better if the wick were a different material, but I've not worried about shedding so much.
I'd like to see extensive lab quality testing, though.
ETA: You have to wonder how many of us have inhaled asbestos fibers over the years from the times when asbestos was used widely in brake linings on cars. I didn't know that cars had cabin filters until one day when the Jiffy Lube guy told me our Explorer needed a new cabin filter. You have to wonder why car makers found it necessary to add that little replaceable part. Maybe they found that we were inhaling rubber residue and who knows what from the road.

It was used to disperse heat and eliminate hot spots.
Are you looking for ViVi Nova coils?
