Why are you assuming gnet are male?
isn't everyone on the internet?
and a doctorate of philosophy in biomedical sciences is such an expert on geology and material sciences.
Just saying, I've seen enough from other sources, the only thing that will convince me that gorilla glass is hardness 9 would be something FROM corning, or from soneone that says 'hey, we tested it, here are the results'. Otherwise it's regurgitated information who's accuracy is suspect.
However, nowhere in Corning's official literature do they ever indicate ANY Mohs rating for it. They only give the Vicker's rating, and they give it well below what other sources besides the one I linked to give for sapphire
I did some more digging for more places that site the vicker's rating of sapphire, all of them give the Vicker's hardness rating of 2000 for sapphire, still well over the manufacturer's specs for gorilla glass.
According to some half-assed googling, it looks like a Mohs hardness of 9 (Sapphire) roughly corrosponds to a vicker's scale rating of 2035.
Contrast that to Gorilla Glass's listed 622 - 701, and there's a drastic difference in hardness that actually places gorilla glass around a 5-6 on the Mohs scale.
Interestingly, Gorilla glass 3 even lists a LOWER Vicker's rating, citing only 534-639.
Hardness does not always = scratch resistance apparently. The Gorilla glass 3 resists scratches a very different way.....
You're also talking about one person's experience with a local farmer, who most likely was not a large commercial dairy operation where the one sick cow could easily be overlooked. Pasteurization isn't because it's common for the milk to be contaminated, but because a possibility (however slim) exists. And would only be amplified by gross capitalism where that one, slightly sick cow is still making milk after all.....
Look at all of the recent incidences of other contaminated foodstuffs (I'm looking at you, Spinach) that have made local news over the last few years. We could have seen just as many from milk if raw milk was still a widely available commodity. Possibly more, as with the spinach it's harder for the contaminate to move throughout the whole batch like it can with a liquid.
