The earrings I'm wearing are borosilicate glass.  For measuring cups I'm holding on to my ancient Pyrex and Anchor Hocking with no markings.  I have old Pyrex baking dishes but I don't bake in them.  Besides they don't fit in the CSO.*

 

 

*unlike the Pyroceram baking dishes that I still occasionally pop in the CSO.

I’ve made roux in Pyrex in the microwave a few times.  It works, but I was always a little concerned about doing it.  That would be like Cajun napalm.

Some info here.

 

Does anyone still make things out of borosilicate glass?

 

Luminarc and Arccuisine  are supposed to be borosilicate. They're both European but I see Luminarc in some stores. I think I read that Luminarc is the spinoff to Europe of the former Pyrex when Corning spun it off, but I may be misremembering the details.

There are supposedly borosilicate (advertised as such) kitchenware in the AmazonBasics line.  The reviews are ABYSMAL.  They are reported to be shattering in varied usages.

Staff note: This post and responses to it have been moved from the Gotten any fun stuff lately? discussion, to maintain topic focus.

 

 

Folks up the road from me are getting ready to move away, so they had a yard sale yesterday. I came away with some low plastic resin tables and a step stool of the same stuff that will come in handy for reaching things in my trailer or loading things into my pickup, and a rusty but serviceable set of tin snips that I need. I resolutely did not pick up the other things that caught my eye.

 

Until today. 

 

I'd noticed that some sensible person had taken the vintage set of 3 Cornflower Corningware baking dishes for $10, but they'd left behind the Corningware baking dish that I thought I could use. I spotted the couple outside, packing to go. They were finished with the yard sale, but happy to sell me that baking dish. And load me up with other things I admired. They were happy to get rid of them!

Two Corelle pie pans, the 2.5 liter Corning baking dish, a 6 cup Corningware kettle, and a Japanese lacquerware tray that I simply couldn't resist. If I never entertain company again, I'll have this to entertain myself.

 

5 bucks for the lot!

How does the Corningware kettle work?  My mother used a Corningware baking dish (similar, if not the same as, the one you just got) and it was oven-safe, obviously.  But a kettle requires direct heat - like over a gas flame, or electric burner which are much hotter than oven temp air.  Or is the kettle more of a tea pot that is meant to have boiling water poured into it?

We had stovetop Corningware (saucepans and so on) when I was growing up, so I assume this is also stovetop safe. It isn't marked either way. I may get a bad surprise! But I may be saving it as a tea pot no matter what, for the times I'm visited by tea drinkers.

 

Really, as long as I don't boil it dry, it should be stovetop safe.

You are correct, to a point, IMO.  You don't know how well this teapot was treated, how many heat and cool cycles it's gone through, or how many shocks going from cold to hot and reverse.

 

Were it my pot, I'd not put it directly on a burner, but if you insist on using it on the stovetop, then use it with a diffuser of some sort.

The USA made corningware can be used over direct heat. I have a skillet and a pot that I use on my gas stove.

Thanks, but can it stir small quantities while frying in a small amount of oil?  Not a quart of soup, but stirring (and wiping the bottom so it doesn't burn) say a half cup of spice paste?

Not something I've used it for - but I suspect it would do it well.

@TdeV Me too!!  One way to see if it would work would be to puree one onion and see if it can fry it at medium heat with maybe 1-2T of oil until the oil separates back out.  I'd love to see how much human intervention it would need to do it evenly.

Next time I use it and need to fry onions, I'll post how it works unless someone beats me to it.

I lose my head everytime I spot the Corningware cornflower in the wild! I have stacks of the stuff- my problem is I don't use it. It's purely nostalgia for me- my grandmother used them a great deal. If I was smart I'd try to trade them for pink Pyrex that I love.

We had that very same Corningware kettle/teapot at home; I was allowed to use it to boil water to make instant oatmeal for breakfast before school.  We had an electric range and it's probably still at home collecting dust in the garage.  My mom won a microwave oven  (when they were the huge hulking devices that were as big as a laser printer is now!) and then we just started heating water in a pyrex glass measure ...
