Stovetop cooking with Pyrex Visions cookware?

Hi Everyone!

I'm a newbie here, and came across this site searching the web for some info about Pyrex cookware. There seem to be some really enthusiastic and knowledgeable people around, which led me to believe I could possibly get some guidance concerning my problem here. Can anyone tell me if one can actually use the Pyrex (Amber) Visions line of cookware on the stovetop? I've seen this claimed at many places, especially the ones that are selling them on auction etc., but I find it hard to swallow that glassware such as pyrex can be used on the stovetop. Is their a chemical difference between the usual pyrex stuff and its Visions line that allows the latter to be used on the stovetop? And are there only certain types of stovetops that it can be used on? Does one have to follow a special heating/cooking technique and precautions while using this type of cookware on the stove? I'm really tempted to use this cookware for my stovetop cooking needs, but having no experience with it, I'd appreciate if you can share your experience and knowledge about this with me. I have an electric stove and the only pyrex I've used before is for storage and some baking.

Thanks for your time,
Anchita

Anchita, that is all I use. I love my visions and use it everywhere. As long as you don't drop it on a ceramic tile floor it is darned near indestructible. One caution though, you need to get used to cooking differently with these. They REALLY retain the heat. You will need to use a lower setting for EVERYTHING you make. I hope you enjoy them, I love mine.

Oh yes, sorry...my range is electric as well, but I have used them on a gas stove with no worries either. And I have been using these for about 15 years or so I think. Don't worry, they will not blow up on the stove top, they are tough.

Thanks Alix, for your prompt and very helpful resoponse! I'll keep in mind what you said about their heat retention, and look forward to cooking with them.

Thanks again,
Anchita

1) Follow the instructions that come with your cookware!!!

2) Never ever set a hot glass pot on a cold metal surface!!! Use a wooden trivet/cutting board or a cloth pot holder or folded up towel to set it on.

3) Never add cold liquid to a hot glass pot ... unless in very small increments - again to prevent too rapid of a temperature change. And NEVER if the pot has boiled dry!!!

4) Let the pot come to room temp before you stick it in the sink or try to wash it.

This is glass cookware - and it is more subject to thermal shock than metal. With metal the worst would be you'll just warp a pot - glass can explode. Like Alix said, this stuff retains heat. Back in 2000-2001 there was a class action laysuit - and Visions was pulled from the shelves in Canada at least for a while - due to injuries. From what I remember readying it sounded like all of the injuries were thermal shock related.

Also, be careful what you expect it to do. In my experience, Visions cookwear is often hard to clean. Maybe I was just using it wrong, but everything except soups seemed to stick to the glass.

To shed light on the thermal shock problem, all glass shares the property of being very stiff and not at all flexible. When metal is taken from a very hot condition and immersed into a very cold environement, the material contracts rapidly. Due to rapid expansion/contraction characteristics of the metal, the outter surface changes more rapidly than does the core. This is what creates the warping. Metal is malleable and so doesn't catastrophicaly shatter. Glass doesn't bend. Instead, as the surface is rapidly cooled or heated, it changes its size rapidly with respect to the inner material. This puts extreme pressure loads on the material causing it to catastrphicaly fail, often resulting in flying shrapnel. All glass and ceramics share this problem, as does ice.

When used properly, Visions cookwear is tough stuff. Used improperly, it's jsut as dangerous as any other glass utensile. It has its strengths, and weaknesses.

Oh one more thing, both enamled cast-iron, such as Le-Crueset, and regular cast-iron pans can also shatter when placed in very cold water after being taken directly from the heat. They aren't nearly as prone to this as is glass cookwear though.

And both Pyrex and Corning glass pots have been is service for use on cooktops long before the Visions line came out.

You know, I was reading the "Don't do" list for Visions and I have to say...done all of it. Oops! I am either very lucky, or I have extra tough pots. I have to say that I have used many different types of cookware, and I keep coming back to these. They are easy, and extremely versatile. I can toss the whole pot in the oven to keep warm, I can put it in the microwave, use it on the stove or the BBQ for that matter. I always put it on a cork hot pad when I take it off the stove, but that is more to keep it from burning the crap out of my counter than anything else. I have put it right into a sinkful of water to wash it (I know! I know...bad Alix!) and I have poured cold water into a hot Visions with no bad results. I AM NOT ADVOCATING YOU DO ANY OF THESE STUPID THINGS! As has been pointed out, they are NOT smart. I am just saying that you don't need to be really anal retentive about using these pots, if you screw up you will probably be fine. Don't stress...just cook and have fun. The biggest deal is the heat retention, just turn your stove down.

I also have been using Visions on the stove for years. Another good rule is always check for cracks before cooking, and don't preheat the burner. The pot has to start on a cold burner, and heat with it. An easy way to clean them is to always spray Pam into them first, and if you still have stuck-on food, put an inch of water and a few drops of dishsoap in(after it has cooled down) and heat it back up. As the water heats, scrap bottom with a spatula. It should come right up.

Exclamation Visions Cookware Explodes!

Hello Chefs!

Tonight we had a 2 quart Visions cookware saucepan EXPLODE into bits on our stove. It looked like brown crushed ice all over the stove, counter, and floor. I wouldn't have believed it had it not happened in our own kitchen!

We've had our Visions for at least a decade and have used it regularly. It was in good shape (no chips or cracks) and it was not experiencing a sudden temperature change either. My wife was bringing potatoes to a boil. It wasn't boiling quite yet, when it simply shattered into a thousand glass chips in a 5 foot radius.

Had my wife been standing closer she certainly would've been injured. I researched around the web and learned that our exploding Visions cookware problem isn't isolated and people have actually suffered life-threatening injuries from Visions cookware exploding just like ours did.

Here are a couple of places I found that discussion on Visions cookware http://www.ellenskitchen.com/forum/messages/387.html & http://boards.lp.findlaw.com/cgi-bin...0@.ef114da/654

Decide for yourself, but we are throwing all of our Visions into the garbage. The replacements won't be Corning or glass.
