Isn't this a wildly misguided assertion? As any antique bottle collector will tell you, bottles underground WILL corrode, and the corrosion is very obvious in less than a century, depending on soil conditions.
Granted that's soda-glass, and there are many types of glass, but just because a bottle can hold sulfuric acid for a few decades doesn't mean all glass will last centuries.
- Pulcinella 6y agoYeah glass is not that resistant to alkaline conditions over long periods of time. You can, of course, perform chemical reactions in them using highly concentrated base, but you don’t want to leave important features in contact with it for long periods of time. E.g. you can wash your scientific glassware with base, but you don’t want to leave it in there to soak. Otherwise the ground-glass joints (rough patches of etched glass used to help connect glassware together) can be corroded and smoothed out.
- Turing_Machine 6y agoRight. He says that glass is the same as quartz, but it isn't. It's got other stuff in it to reduce the melting point and improve other working characteristics. Most everyday glass is soda-lime glass or (less commonly than in the past) lead glass ("crystal"). Lab glass is often borosilicate glass. All are pretty durable, but not anything remotely approaching pure quartz.
