<p>Passing a fund raiser this am and purchased a box of Pyrex tablewares. On the bottom, the stamp only says “Pyrex Tableware by Corning, made in USA”. How do we know if these could be used for microwave oven heating?</p>
<p>Paid $0.25 each for the whole box full of them. Hopefully we could find some use for them.</p>
<p>If they’re the white Corningware or the clear Corningware, both of them can go in the microwave, as well as the oven or under the broiler.</p>
<p>Sounds like you got a great deal!</p>
<p>Hi VH, these are white Tableware with very simple red decorative “whatever you call those” alone the rim. These are no clear one nor Corningware. </p>
<p>May be these are pre-microwave oven?</p>
<p>Test one piece. We were told a long time ago that you could put it in the microwave with a cup of water for a minute. If it comes out hot to the touch it most likely will not do well in the microwave.</p>
<p>Let us know the results.</p>
<p>SM07, that is an excellent idea. So I went ahead and did the experiment. </p>
<p>Put 2/3 of bowl with water and set microwave for 60 sec on max. Afterward, I could use my bare hands to take out the bowl and the water is definitely hot. I think that says these bowls are microwave safe.</p>
<p>Thanks!!!</p>
<p>What a great deal you got!!</p>
<p>I’ve used Pyrex dishes in the microwave for years. They’re pretty durable. Good find DadII.</p>
<p>They should do well in the microwave, but may not do as well in the dishwasher. [How</a> to Clean Pyrex : Pyrex Love](<a href=“Welcome to Pyrex Love”>How to Clean Pyrex : Pyrex Love)</p>
<p>I think the test is to put the (empty) piece you are testing in the microwave along with a container of water. If the piece is microwave safe, it will not heat up beyond the microwave’s internal temperature</p>
<p>Most vintage Pyrex is microwave safe and safe in the oven at temps 450 or less. They’re not for stovetop use and their color may not hold up in the dishwasher. The link above is an entire website on Pyrex.</p>
<p>THis test suggests using an empty dish to test if it is safe.

<p>Corelle answers this on their website. Easy to look it up: [Which</a> products made by Corning are safe for microwave use? - Corelle Pyrex Patterns Dates Information](<a href=“http://www.corellecorner.com/quick-questions/137-which-products-made-by-corning-are-safe-for-microwave-use.html]Which”>Quick Questions - Dates & Details for Collectors of Corelle, Pyrex, Corning Ware & Centura)</p>
<p>But for all your readers here, FYI, putting a glass or measuring cup of water in the microwave can be very dangerous. The water can “explode” or the glass shatter.

<p>Are you keeping them or selling them on ebay?</p>
<p>Dad II…are these for your family to use, or will you be reselling them…maybe on Ebay?</p>
<p>LOL crossposted!</p>
<p>How many and which pieces did you get? Are these assorted loose pieces of plates, cups saucers, etc or a complete set of service for, say, 4 with dinner, dessert, cup, saucer, etc? Was it a closed box of dishes or a box with assorted dishes in it?</p>
<p>jym, I boil water in pyrex measuring cups every day! Literally. I use it to make tea and French-press coffee.
But If the water is not actively boiling, I don’t take the water out the minute I turn the microwave off. I let it sit for a bit.</p>
<p>Be careful, mafool!!!</p>
<p>Thank you EK4. The question is then the definition of “warm” and “lukewarm”. Since we use them for occasional reheating, I think we are fine. </p>
<p>T1, with over 120 positive (100%) feedbacks as an Ebay buyer, I have yet to sell one single item on eBay. Not going to start with these Pyrex. As a matter of the fact, after a very good cleaning, we are using them now for dinner. Over the last 20 or so years, our old bowl set has only 3 good ones left. </p>
<p>The “new” set has 14 pieces. I guess they should last us another 20 years.</p>
