Are these jars oven safe?

We put honey in ours, which we don't want to heat. That being said, if the lids are screwed on, I think these could easily break in the oven. You might try one without the lid and see what happens. Glass is often used in ovenware, but not with a sealed lid. The contents could expand with heat.

I have not used them in a conventional oven, but in the microwave oven. So far, they appear to be safe in my micro. Hope my comment helps.

Yeah I don't see why not. They won't seal like a normal mason jar lid but should be just fine to put on strait out of the oven

They are oven and dishwasher safe. They do get extremely hot and I wouldn't place them in the oven even if it said I could

They are not oven safe - they melt at high temperatures and you would have a real mess. You can't leave them on while you're cooking on the range, either, and for exactly the same reason. They are nice if you have a tendency to 'dunk' your potholders in whatever it is you're cooking, but I don't think I'd buy them again.

Sorry I do not know if the top are oven proof. But yes you can put them on hot jars.

Definitely do not put the lid in the oven, as the plastic will likely melt. The glass parts are oven safe, and I have used them in the oven to warm up leftovers (~300F for 10 min). However, I would not recommend them for extended use, as they are not as heavy duty as a regular bake ware.

I don't know about using them in the oven but I use them for leftovers daily for usage later on. Not sure whether oven usage is a good idea.

Hi I would think they are oven proof glass. They do have plastic lids which would not be. I love them. The are heavy glass, easy to clean and very microwavable. I tossed all my other storage and this set is all I need.

I doubt they're ovenproof. however, I have put them in the microwave and all was OK

I don't think they are oven proof. I haven't used mine in the oven, can't remember if the info specified oven proof or not.

I have been using them for decorative purposes only on cookies. I've not put them in the oven. It doesn't say on the jar. Don't think I've been much help.

I wish I could help you, but I don't know. I would assume that the lid is not oven safe as it is a different plastic than the bowl. I've only used the bowls in the microwave, thus have never tried them in the oven.

Hello Suzanne. Unfortunately, the weck jars are not tested for oven safe. We do not recommend using the weck jars in the oven. They are wonderful for canning and putting all your spices and coffee and ingredients in as well as fun and creative crafts. Hope this helps and answers your question. Liquid Emporium

I can't say that I've actually tried (I used them as vases), but I can tell you that they are a tad bit more substantial than "Mason" brand jars. I don't see why they wouldn't be oven resistant so long as you put them in a pan with an inch or so of water in it...

My understanding is that they are. I have not used mine in the oven yet, but would not hesitate to do so.

No, they are not oven safe. I don't recommend putting the lids in the hot dishwasher either, if you want them to last. Nor on a hot dish out of the oven or filled with hot food. They are plastic with a rubber gasket, which is removable which I clean by hand with a brush. Also let the lid dry thoroughly before snapping it back on the clean dish. Love the nesting storage space saving sets. I Hope that helps.
