Title: Cheap soda-lime, not borosilicate
Product review: I had a 500ml Pyrex measuring cup that I put on the stove (on low heat) to dissolve some malt extract for brewing. I've done this many times with a borosilicate erlenmeyer flask, but figured this was more convenient. Well, while I was gently stirring, the thing exploded into many tiny fragments, some of them thrown several feet away, some of them even getting stuck to my clothing. Thankfully I didn't get anything in my eyes, but I spent the next hour cleaning the stove and everything around it.After some research it appears lab glass Pyrex and kitchen Pyrex are two completely different products. Some time ago the company switched to soda-lime glass (the same stuff used for common bottles) to cut production costs. The Pyrex website claims it's because soda-lime is more durable when dropped, but I thought people bought this stuff for its supposed heat resistance.
Would you say this review depicts the product in a flattering or unflattering light?
