Remind me... How do you make sure glass doesn't break??

annimal Dec 25, 2006 03:48 PM

So I just had a fairly traumatic experience... I had a plate in the microwave and all the sudden I heard a pop. I look in and one of my vintage depression glass plates had broken. I completely forgot about hot/cold foods and glass... Now that I've learned my lesson the hard way (and will remember to always get out my microwave safe plates in the future), I realized that I can't even remember what the rules are about cold or hot foods and glass.

RIP Hazel Atlas Ovide plate... :(

    Glass breaks when it is heated unevenly. Like in a microwave, the potato
    is getting really hot and heating the plate underneath it, but the rest of the
    plate is staying nice and cold. Expansion/compression/cerrrackk!

        Wish I would have read this thread before dumping hot tea into my favorite glass pitcher.

          Along the same lines (sorry about your dish) I was roasting a chicken for three of us today (yes, Xmas) and my oven safe, baked in it before, ceramic or earthenware-ish dish popped in half and flooded the bottom of my oven...causing enough smoke so that no one could breath. The oven was at 450 (first half hour of roasting) when this happened. Was it just too hot even though it said 'oven and dishwasher safe'?

          No worries - the chicken was saved and tasty.

            Your dish probably had non-visible stress fracturing from prior stress. When dishes are banged down and don't break, we tend to assume the dish is OK. It may be. It may instead have developed a stress fracturing process....

            Any changes in extreme heat is bad for glass. MV safe is just that, everything else is chancy. Depression glass in MV leads to depression. The spoon in the glass works if sterling and can conduct the heat quickly and efficiently.

              oh yeah, it's all microwave safe dishes from now on. i was thinking more in terms of other glass items, like bakeware etc., since I know I've heard some basic rules about temperature and glass. as for my plate, i think it was more likely what Candy said about glass fatigue, as the plate had been in the microwave for less than a minute, and the food was still fairly cool.

              thanks! now i've just got to work on replacing the plate, the pattern I have is not as common as i'd like.

                I had a dumb moment when trying to extract a frozen daiquiri mix from my glass blender jar that was straight from the freezer, by running hot water over it. CRACK! What was I thinking?!

                I think basically the way to keep glass from breaking is not to go to extremes too quickly. Hot to fridge, not freezer -- frozen to room temp before heating.

                  Ebay is a really good source for finding vintage china and glassware.

                  Another good option is www.replacements.com although it's more expensive.

                  a spoon in the glass before pouring the boiling water--also if you have a glass table top as I do--put something underneath a hot from the oven dish (ie. bamboo mat or insulated cloth)or your tabletop may crack and break

                    Old glass in a microwave is a real bad idea. Old glass can develop glass fatigue and when put under any stress can shatter.

                      put a spoon into a glass cup or mug when using boiling liquid.

                      Microwave and vintage just do not go together, I guess.

                        >>put a spoon into a glass cup or mug when using boiling liquid<<

                        I'm assuming you mean when pouring hot liquid into a glass cup or mug? . . . One should NEVER put a metal spoon into a microwave.

                        And as for the other, make sure to use microwave-safe dishes in the microwave, and you should be fine.
