are they like pyrex which can go from refrigerator to microwave?

I have put them in fridge, microwave, and dishwasher without any issues. Also, I have found silicone lids which make them a brilliant storage solution.

I have used them in both the microwave, and the fridge, but they are not as strong or durable as my Pyrex ones. I hand wash them to be safe. They are great mixing and serving bowls, and worth the price, in my opinion.

Yes these are high density Pyrex Bowls. I would however NOT recommend going from a hot oven to cold water as these will crack/break.

I haven't tried to put them in the microwave but I would think so as it's glass. Apologies I can't be of more help.

I have not tried to do that, but they should be OK if you're not cooking for long periods. I generally avoid putting ANY plastic in a microwave for a number of reasons.

Hello! I personally have not tried to microwave with them, but from what I read on Google, you can, but probably shouldn't be an everyday practice due to chemicals that are released and the "hot" plastic that results from the microwave. Here's an example of what I read from Google: There can be a very small amount of migration of the melamine-formaldehyde resin, but as you stated elsewhere, the FDA concluded that it was well below the safe use limit. However, the real reason for not microwaving melamine dishes or cookware is that it can become very hot when microwaved. Most plastics are microwave transparent and do not get hot. Melamine absorbs microwave energy and, as a result, heats. Hello!

"Pyrex" made by World Kitchen is no longer made from borosilicate glass. When Corning sold the brand in about 1998, the new owner - World Kitchen - switched to tempered soda-lime glass. I have found that these work fine for food storage and re-heating in a microwave. The plastic lids are great when they are new, but if not careful when removing, one can bend the rim too hard and eventually the rim of the lid will crack. I wish they sold lids separately as replacements.- I also have some old Pyrex 2-cup storage containers that I believe are borosilicate glass. The borosilicate is more clear, whereas the soda-lime has a slight green tint when you look down on the edge. Both the old and new containers are marked with the same lettering on the bottom "2 cups - 470 ml Made in USA, 7200, Pyrex, microwave safe, no broiler, no stove top." All-in-all these are just right for taking leftover dinner to lunch the next day; good size and much better than microwaving in plastic containers which can release dioxins into your food ---

These are much better. I've had them in quite hot microwaves with no melting. (No doubt the venting helps too!) I think you'll find that they'll do the job for you just fine.

Check out the question "Are these bowls like Pyrex" where one comment reports finding lids by Lekue on Amazon that work with these bowls.

I suspect Pyrex is Pyrex no matter where you go to purchase it. Since I did not buy these at Macy's there is no way I can address this question, other than to say Pyrex is sold in many different stores.

I do not think so, but don't now for sure. The reason I say this, these lids are glass with a rubber seal...this is a question for Pyrex directly.

I have used mine in the microwave for months. However, I would recommend putting it in before heating the oven instead of putting it directly into a hot oven: Pyrex glass is quite heat resistant but can crack from "shock" (a sudden big difference in temperature).

It's pretty thin plastic - like you would get cole slaw or condiments in. I have not tried them with hot liquids. I would not trust them in a microwave oven, as I think they would melt.

No... not pyrex... and would NOT put it on an electric stove. Works great, though, and very convenient.

Yes. Pyrex can handle anything poured into it . They are not pans and should not be put on the stovetop. Use in the microwave very carefully and not to boiling!!

No. The polyethylene plastic of which they are made is not suitable for use in a microwave oven.

Heavy duty but don't think it's pyrex - we make sun tea in it and that works great - can just stick on refrigerator shelf when done - don't think I'd try boiling water.

According to their website, www.calibowl.com, they are. I don't think I have put mine in the microwave yet but that's just because I haven't had the need to do so. Check the website to be sure.
