  > Comparinging by volume produced/consumed, I think it's reasonable to pretty much ignore all non-borosilicate glass Soda–lime glass accounts for about 90% of manufactured glass. ~ https://en.wikipedia.org/wiki/Soda%E2%80%93lime_glass https://en.wikipedia.org/wiki/Soda%E2%80%93lime_glass The implication being that borosilicate glass accounts for at most 10% of global production. It's the dominant type for thermal | bakeware where expansion factors matter, but overall not the most common glass type in production. > And the snark doesn't add to the discussion.

    Apologies for getting my facts wrong. You are of course correct. Re: snark - the point of HN is that we are better than that. If someone is snarky, then we shouldn't respond in kind. But I get it. It's easier to say than to do.

      Consider this, I've responded to an ill considered disrespectful one liner with a wealth of information about glass. At no point did I claim that rare earth in glass was a bottleneck to solar panel manufacture, glass only arose as doping glass for specific properties is one of the many reasons why we process rare earth materials at all.
