And this is precisely the good stretch of silicone products.
Two, the anti burn in the flame contact lenses, lens will be curled up hard, slowly get out of the light blue flame, then start burning lens. After burning, the rest is gray dust, the gray matter in the silicon dioxide, which is the same as the silica gel products produced after combustion is the same
