It's unclear what the advantages of borosilicate are from this discussion. Is it merely the lightness? Either-or would seem to solve the problem of microplastic release on microwaving.
We use plastic containers largely for convenience. They're durable, malleable, and don't shatter like glass. They're also lighter and thinner, and cheaper. This makes them useful for things like takeout containers or any situation where you need to transport food. Borosilicate is more durable than regular glass. It's generally less prone to shattering, and it's also more tolerant of rapid temperature changes. As far…
You sure about that? I always heard that borosilicate was significantly less durable (30% is the figure I remember, not sure if that's 30% less or 70% less) and all the thermal shock resistance came from lowering the CTE.
I don't know if that was a half truth from a soda-lime salesman or if nostalgia googles are giving borosilicate credit it does not deserve.
