seems mix, bright blue looks Capital letters and the others are lower case, but best to go instore and check coz:
This vid should be watched by everybody it is a total revelation! Many thanks for the link.
@Huntakillaz Thanks for the link. Very informative video and I love her scientific approach
Yeah she's very good with regards to cooking stuff and debunking myths or false videos. They're also Aussie too
If the logo is in upper case lettering, PYREX, it's most likely made of borosilicate, and thus safer. The lowercase lettering is most likely made of soda-lime glass, so take extra care after any high-heat cooking.
Pyrex eventually switched to tempered glass most likely because boron is toxic and expensive to dispose of. Although tempered glass can better withstand thermal shock than regular soda-lime glass can, it's not as resilient as borosilicate. This is what causes the shattering reaction people are talking about.
Puzzling that there's negative voters on this comment. It's a legitimate issue.
The negative vote is likely for plagiarism (not my vote, therefore assuming). They didn't cite the source, but copied and pasted text from a website verbatim without citing it.
Oh dear. We should all be brandishing pitchforks in that case
These pyrex measuring cups are pretty crappy. I have two and the cup and ml marks have rubbed off on both making them pretty much useless.
Yes the lowercase pyrex are shit! I just rubbed off half the markings by handwashing and drying it this morning. Only bought less than 6 months ago.
Same here. Bought from Woolies, one side of the marks are lost
These jugs are also inaccurate, 250ml of water is not 250g of water in that jug
The Decor ones from Woolies are no better. I've just had to buy a replacement as the markings have worn off.
This pyrex is crap, had the handle shear clean off the measuring jug leaving a sharp dagger that sliced my hand pretty good.
I had a pyrex jug disintegrate into hundreds of pieces across the kitchen bench one time, scared the crap out of me when it happened as it had been sitting there empty for a good few minutes. Made a decent noise when it happened lol.
Also don't pour boiling water into glass straight from the fridge it will shatter/crack
My boiling water comes out of the kettle bot the fridge. :0
That would be general advice about glass, not just for this jug. I'm disappointed by the other comments about it though.
Yes and no? Borosilicate glass is designed for that.
TIL, thanks.
Yet from my brief googling, Pyrex is borosilicate. And from the comments, you shouldn't trust it.
@pizzaguy: Soda lime pyrex is the one that explodes. It's designed to shatter safely, which it does if you so breathe too hard on it.
Borosilicate PYREX is the one that is designed to take the heat. It shatters into shards, but that's fine if you're able to not drop things.
@pizzaguy: Don't Google, watch the above vid - pretty much everything is not to be trusted "at a glance" if she's right.
Borosilicate glass will still shatter from rapid temp extremes.
Going straight from the oven to water for example, or if you are doing some weird heating at one end, its just way more resistant to it.
Did you not do science in high school? This is pretty basic stuff.
You'd be surprised.
I had some arrogant pricks (a group of 3 men and 1 woman) laugh at me when I used my water bottle (I cycle to work) to help clear their windscreen frost… they claimed it would never work and that my water bottle should have hot water for it to work.
When I ignored them and started pouring and the frost started clearing, they laughed again and said something about me stealing the water… not even a "thank you"…
I told them it shouldn't be hot water, but they ignored me and started laughing at me again. 🤷
I had a similar opinion to you thinking everyone would've learnt about this at school (or even just from family/friends teaching them the simple science of clearing widescreen frost), but all four of them had no idea…
It depends on the temperature of the glass to begin with, it doesn't necessarily have to be from the fridge for it to shatter. If ambient room temp is low enough, the thermal shock could be great enough to break the glass.
Have a Pyrex measuring cup myself, only gripe is I have to pour stuff out somewhat slowly as it spills over the edges of the spout. Reading some comments on here though is a bit worrisome.
This is the whole point of borosilicate Pyrex, better temp shock resistance. Alas, they cheaped out and went with sodalime for the Australian/US market
Kmart do a one-litre borosilicate jug for $8.
Bought a couple for reheating frozen leftovers and such - no issues for the several months I've had them.
Larger size makes them useful as mixing bowls.
I wasn't concerned so much about the markings but they remain intact after dozens of dishwasher cycles.I have had the 500ml version for about a month and the markings are rapidly fading with dishwashing.
Just measure the water before you put it in the kettle to boil?
Or pour kettle water into cup on a zeroed scale to measure volume 1g per ml.Yep. I kind of wondering what do you have to measure at boiling temperature?
I use it for those DIY bubble tea kit at home.
I think people use electric kettles which have a minimum volume (eg 700ml), when they only need, say, one cup.
Clearly these people haven't (properly) watched die hard with a vengeance
Pretty much.
Or I pour pre-boiled water from thermos which I still need to measure.
kettles which have a minimum volume (eg 700ml), when they only need, say, one cup.
700ml is basically 3 cups…
Consider the IKEA 365+ stuff instead. The lids seal better.
I find that with our pyrex stuff, the lids can split on the side, and clearly aren't intended to be water tight. But the IKEA stuff seals really well. No long term experience yet.
A quick search shows conflicting information about whether it's borosilicate or soda lime.
Can confirm Pyrex lids split for no good reason
Plenty of ours are split. Went looking recently for replacements - the prices are insane for plastic lids.
So far 41 upvotes, but among 36 comments plenty of negative ones and no positive…
I'll give a positive endorsement: I believe they are better for you than plastic storage containers. Evidence seems to be coming stronger that food in contact with plastic, especially when heated, get contaminated with plastic, and that over time these are cumulatively not good for you.
If you share that concern then pyrex / PYREX is a good option. We switched from plastic containers to pyrex a couple of years ago, and don't microwave the lids.
But in my experience, the lids still split. We probably have 3-4 split lids over a couple of year from a fleet of probably 20 containers/lids
If you're looking to do the same, then pyrex, treated with care, is a good choice. As I said in my previous comment, we're in the process, probably, of switching to IKEA's 365+ range, just because the lids seal better, and you can buy separate lids when you lose them or they wear out.
So it's positive endorsement but you're switching to IKEA's, which is fair enough and I'd trust IKEA more too.
Still nothing positive about Pyrex specifically.
PYREX or pyrex?
