- cullenking 16y agoThe melting temp of borosilicate glass is higher. In glass production, most of the cost is the energy expenditure required to keep the kilns hot (they never turn off). By dropping to a lower melting point glass, they can shave a substantial amount off their energy bill.
- code_duck 16y agoBorosilicate is a lot more difficult to work with in general. Basically, they cut corners and downgraded goods available to consumers, as companies have done with many other products in the past 50 years.
