OK, Not What They Were, But Still Probably the Best Alternative
on April 8, 2018
We've only had these a short time, but so far, they seem great. I was a bit hesitant to buy them, given all the hyperventilating I see in many of these Amazon reviews, going on and on about them supposedly being hard to pour from, and supposedly being prone to exploding because they are now made of the wrong kind of tempered glass (now soda-lime rather than borosilicate). Two damning faults for a glass measuring cup, if true. In the end, I bought them because Cook's Illustrated rated them as the best of the 15 they evaluated. Their tests included pouring from the cups and heating in the oven, and if they didn't find a problem, I decided to trust their recommendation. In the past, I have found them to be reliable, so I went with it.
Certainly these are nice cups....well made, easy to read, comfortable handle, and accurate.
But what about those two supposed faults? The pouring thing is just not an issue....liquid pours out just fine, without running down the edge. As to "exploding", that of course would be a result of thermal shock, and the old borosilicate is in fact more resistant to that (although apparently also more brittle). As a result, you do indeed have to be more careful with these versions than with the old PYREX (all caps). A pity, but that doesn't mean they aren't useable...you just have to be careful to not shock them (like take them from a hot oven and place them in a puddle of water on your countertop.) So they lose 1 star for that. Having said that, I just looked at some other 13x9 pyrex (not caps) we have had for some years. They are clearly also made from the soda-lime glass vintage, with the same heating cautions printed on them. Being oblivious to the change in glass till now, we have never taken any great precautions with them and despite that, we have never had a problem with them.
Now, you can in fact search around and buy the PYREX (all caps) products made in Europe, which still use the borosilicate. However, while the indications for an ounce are the same, a UK pint is 20 oz, versus in the US it is 16....so a little awkward here, I think.
So, while I now see we should take some cautions with these cups, we haven't had a problem with other pyrex products of this glass, so I'll continue to use them.
