> features an amorphous silicon dioxide coating that's infused into the inner-wall of the bottle. Essentially, this forms a glass-like finish that provides a totally natural, and completely inert, solution to the problem "glass-like" != glass Dollars to doughnuts that coating is spray lined. Which means some sort of solvent, at a minimum. And I'm unaware of any way to fuse silica at temperatures under which plastic would survive, so it's a coating with a binder (dissolved in the solvent) which can still be damaged, scratched, leach or flake off into the water. I wouldn't touch it with a 10 foot pole. Glass, stainless steel (316 please), or ceramics for me.
