AR states they use silk that is made from silk worms who are fed Tourmaline powder to produce silk with Tourmaline in it to provide promotion of negative Ions in their panels.
It wouldn't surprise me at all if they actually did it as I have seen weirder shit in this hobby.
Would it work? I honestly don't have a clue but I would have doubts given what Tourmaline powder consists of. I would tend to think that something as small as a silk worm would die from it long before it could produce silk.....but like I said, I honestly don't have a clue.
