Should a warranty problem develop, contact our Consumer Care Center. When cooking vegetables, potatoes, or pasta, boil water first, and then add food slowly to boiling water. For anything other than boiling water, use a low to medium heat; too much heat causes food to stick or burn.
Place food off center in skillet, as center area stays cooler and food will not brown as well there. Yes, handles and rims may get hot during use. Fingers and hands may be burned. The Corning Visions cookware line has been discontinued for quite some time. While it was heavily rumored that the products fracture or explode under high heat, numerous tests under intense scrutiny could not duplicate any such results.
Visions cookware can be used on the rangetop gas and electric , in the oven conventional, convection, and microwave , and under a broiler. It can even be used on a grill or over a campfire! Likewise, casseroles and pots marketed for the oven are still stovetop safe. Can I use Pyrex on stovetop? Pyrex glass or borosilicate dishes, pans and other bakeware products can be used in preheated ovens but should not be used on top of any stove, including ceramic cooktops. Which CorningWare is valuable?
Patterns considered rare include: Black Starburst percolator only , Blue Heather, Is corningware toxic? It is unsafe to use corning ware on the stove top and broiler. No second-hand accounts, please, because they tend to acquire embellishment along the way or the facts are tainted, i. Similarly, don't confuse midth century white Pyrex with Corning Ware Pyroceram. Lastly, stories about chipped, cracked or otherwise structurally compromised cookware don't count. Cracked cast iron has been known to explode but no one's circulating internet rumors as gospel truth about the "dangers" of cast iron.
Product defects do occur but I'm referring to the widely circulated accounts of a carefully maintained item breaking from normal cooking temperatures or minor thermal shock less than glass-ceramic's threshold of degrees F as a reason to throw the stuff away and pull it off the market.
I don't work for World Kitchen and never worked for Corning but I have a feeling if you track down the truth, you'll find misuse, abuse and negligence as the root causes, not a manufactured-in "tendency" to failure. I have a lot of old pyrex and corning cookware and have never had a problem. I remember using glass coffee makers that just perked and perked on the stovetops.
Never had one explode. I think they should be handled carefully and not change temps suddenly and make sure there aren't scratches or cracks in them. MIL used to always cook with corningware on her stove top and she never had a problem. I inherited a few pieces and they seem indestructible.
I handle them with care as they are old but they come in handy to just set them on the table as a serving bowl. I always use a towel under them as they are easier to handle that way. I think I only have broken one of my pyrexes by dropping but the others have gone to potlucks and not returned until after I have bought replacements. I use them in the oven or MW small ones or measuring cups , they are hot when removed but I either place them on the stove or on a folded towel.
Tempered glass has an undisputed characteristic of being weakened by scratches. It has happened to several people in the Bath Forum, who had their glass showers unexpectedly explode. It's why they warn you never to use any bare metal that might scratch the glass panels and cause a materials failure. So for example, we use a hook for hanging a bath towel - but it's rubber coated, not a standard steel "S" hook.
I don't know if she's still on the Kitchen or Cooking Forum, but a member here did post an actual experience of a Corningware baking dish exploding in her kitchen from thermal shock. It was old, and they do scratch after a while. I think she reported it at least two years ago, so she may no longer be on the boards.
I remember it because she had walked out of the kitchen for a moment, and that's when it happened. She felt lucky no one, including her children, was in the kitchen at the time. Salad Master cookware question.
Any Corning Ware Users Here? Induction Cookware. Fovorite cookware? I have one time when my MIL accidently set it on an electric burner and turned it on. Does that count! It really did explode if that's the right word. Glass flew everywhere in a million pieces. AND it will break if you put it in the oven on a lower rack on a high temperature. I heard someone post this on a forum before, they were all upset that it broke but you aren't supposed to put it in a high oven on the lower rack!
Yes, Elery had a set of Visions cookware and it did actually "explode", if by that you mean it was used on the cooktop as instructed and it shattered while in use. He was using it to cook macaroni. My ex-MIL also had a Visions saucepan break while in use, although it only broke into several pieces, it didn't actually shatter. She was using hers to cook green beans.
And, as an added bonus, they both said it was the worst cookware they had ever used for the stove top, it was better for the oven. I've only had a Corningware glass pan shatter when I took it from the hot oven and set it on my tile countertop, apparently too cool a surface.
Now I set things on the pot holders. I still have some old cornflower patterned Corningware that I love, I think it's as old as I am and I've had no problems with it, including a stove top percolator for coffee when the power is out. Last night my pyrex mixing bowl broke into 2 pieces when I ran water in the bowl still warm from the oven. I didn't think it was that big a thermal shock, but I knew it was a risk, and there weren't any dangerous shards.
I figured the glass explosions might be exaggerations, too, until I read the Consumer Reports article last year. Here is a link that might be useful: Consumer Reports Investigation subscription may be required.
I had a Visions sauce pan. Put some frozen broccoli in it, put it on the stove top and next thing I know, glass was everywhere. I dont know if it shattered or exploded but there was glass everywhere. I've never had any problems with Corningware or the visions cooktop pots but I did have a bad experience with a glass baking dish made by Anchor Hocking. It was new, and I was at my bother's house. I baked a 9 x 12 batch of cornbread and when we took it out of the oven, it had fine glass shards all over the top of it.
My brother took the whole thing, cornbread and all, back to Walmart where he had bought it. That is true. Tempered glass is used in shower doors and the like where it is supposed to break into small harmless pieces when damaged rather than large, sharp shards.
However, I am unaware of any tempered glass cookware. I believe cookware is made of borosilicate glass, which withstands thermal shock better than plain glass. World Kitchen and Anchor Hocking now manufacture all of their glass bakeware using soda lime glass, which is less expensive to produce than borosilicate.
Soda lime is commonly used in products such as drinking glasses and bottles. It's not clear when the switch occurred. Anchor Hocking spokeswoman Barbara Wolf says borosilicate glass was phased out by the industry by the early s. My knowledge of glass cookware is really out of date, isn't it. I should have done a search, as I usually do on technical matters, to confirm that what I was about to post was accurate.
Or I could have read the linked article which says, among other things, that "A Corning educational booklet from titled "All About Glass" describes soda lime as "the lowest in cost of all glasses" and notes that its "resistance to high temperatures and sudden changes of temperature are not good.
Now I'm not surprised there are problems with glass cookware. Soda lime glass doesn't seem to be an appropriate material for this use, tempered or not. I am sitting here with one hand bandaged and the other in a splint awaiting surgery to re attach my tendon and nerve in my little finger.
Cast iron coated in porcelain enamel is an option on a glass top. Make sure the finish is smooth and covers the cast iron completely to avoid scratches. Stainless steel is the metal of choice for ceramic or glass cooktops. Are glass pots good for cooking? Glass cookware is quite safe if it is new and handled to prevent breakage.
Some not so healthy components used in the production of glass such as lead and cadmium leach into food during the cooking process. My advice to you is to keep those older pieces of glass cookware on the shelf. Why was Visions cookware discontinued? The Corning Visions cookware line has been discontinued for quite some time.
While it was heavily rumored that the products fracture or explode under high heat, numerous tests under intense scrutiny could not duplicate any such results. Finally, one more thing, avoid using the ceramic cooktop cookware that is made with low-grade stainless steel or aluminum. These types of cookware warp easily and are therefore incapable of maintaining even heat distribution.
