I want to give these as a gift with homemade jam. Can I safely boil them for canning? How about oven safe?

I honestly don't know the answer to this question. I bought them to use as a drinking glass and never tried to can anything in them. You should ask the manufacturer.

These jars isnt for homemade jam, its only for drinking cold drunks out of them. On the bottom of the jar it says not to put anything hot in it.

they say not to use these in or with heat, and not made for canning right on the box they come in, you'd be better off going with the regular jars made for canning!!

the instruction book says; some glass stovetops may not produce enough heat/energy required for safe pressure canning-suggests not to use. hope that helps

I have never used it for this, but I think it would be fine. You can put them in the oven.

I haven't tried to put them in the oven. I've read about things you can cook in a mason jar but haven't tried it...I like them because they look good.....

They are advertised to be oven safe. I personally have not used mine in the oven.

I've never used them in the oven, but they are safe in the microwave, which can heat up food to a fairly high temp. The lids are definitely not safe in an oven, but, I would think that the glass could handle lower temps. To be sure I would try contacting the company.

Yes...These are oven safe. The company included a recipe for english muffins and crumpets which describes baking them in an oven. I actually use them on a griddle to make Alton Brown's english muffins.

They're hard plastic, so I would use soap and water. Probably not boil them. (I didn't really use them much because they were too hard and uncomfortable for me.)

I can't see why not, as long as they're no boiling. Pureeing soup etc. would be fine. I like mine so far.

It is safe to pour hot food or liquid into these bowls. They are not safe, however, for direct heat so you can not use them to cook with direct heat on a stove. I don't think they are intended to go into an oven either. They are not cookware. But hot liquids in a mixing bowl is fine.

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...

The plastic is tough enough that I am sure you could put them in a pot of simmering water. I just have never done it that way and thus do not know how long you would want to leave them in. I would not boil them though.

I use mine for freezing and they work out very well. It is recommended, though, that once they are used for freezing (or microwaved) that they should not be used for canning.

Cannot be used for canning, would not be safe!!! If you have the jar attachment it can be used to store dried herbs and dehydrated vegtables.

Absolutely! I use mine every week in the oven or microwave. The first time you use them, you need to spray them with a cooking spray. Since I use them so often, I don't spray them with cooking spray anymore. The baked product comes easily out of the silicon cup. This is true whether in oven or microwave. I have even used them for a molded baked custards and individual molded jello desserts.

I bought these as gifts, but I don't see any reason why not to be able to use them for hot liquids. I can tomatoes and jams in boiling water - why not tea?

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