I love the look of these jars, but for what I want to use them for, I need to pour in boiling water. Does anyone know if they are heat resistant?

they are for sealing and storage, you should be able to sterilize them with no problem.

http://nchfp.uga.edu/how/general/recomm_jars_lids.html the national center for home food preparation (yep, there really is one) recommends following each manufacture's direction on box, but I was taught that keeping them hot in a water bath helps with them not wanting to slip off after placement. As I can be a bit clutzy, I need all the help I can get!

Linda, sorry I do not know...These glasses have not been put to any type of heat test. The density of the glass is greater than that of a regular glass. I trust someone will be of greater knowledge/information. I am guessing they could handle boiling water with no problem...beyond that???

I don't think that you should put these in boiling water. They might have chemicals in them or something.

No, they are very heavy grade commercial aluminum so they heat and cool much faster than stainless. Also significantly less expensive than commercial stainless. The other side of the coin is that they will damage more easily. But as heavy as they are they should last for quite some time as long as nobody accidentally bends or crushes one. Good luck!

Yes, you can put them into the oven. I sterilize them before canning by putting them in the oven. When I can jams, I put them in a boiling water for 10-20 minutes and that also works fine. I have only used them for canning, but if I can boil them in water and put them in the oven, that suggests that they are quite heat resistant.

the answer left by Julia Williams is totally correct. use them for vanilla extract and keep some around all the time. love the jars

These jars are marketed as canning jars, so they should be able to withstand extreme heat. I do not think you could use them from frozen to heat without thawing first, but I think freezing should be OK too. Just be careful of the temperature transition.

Hello Shelly, I am glad to answer your question...these little canning jars are so handy in my kitchen/home! Even though they are meant for canning and can withstand a fairly high temperature, I would not put them into the oven. I use them for keeping small amounts of cooking ingredients that I use often and do not wish to handle the large containers which these ingredients are originally packaged. Also, I have given a few to friends who saw them and admired their "just the right size" feature for lots of things throughout the home. I plan to order more in the near future.

Cap is made of plastic. I don't know how heat resistant it is but I wouldn't try boiling water with the cap on.

No. The lids aren't true seals for the jars. These are more of a table decorative item

Jars directly on the bottom of a pot get too much heat and may crack. Items like this help insulate the jars and keep them intact. And it's much easier to remove then from the boiling water. Highly recommended.

Yes they are heat resistant and no need for pot holders. The handles have a rubber like coating so makes them easy to grip and yer fish fryin' easy!!

THEY ARE NOT AIRTIGHT!!!!Good for crafts or buttons I guess?The plastic seal between the metal cap and the jar is not designed to be airtight seal.

sorry.. I don't really know.. i was them all the time in the diswasher and my wife warms them in a baby food jar warmer that "boils" / "steams" water over the bottle and never had a problem. the top are DEFINITELY NOT heat resistant though.. do not dishwash or microwave them.

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 never heat with the lid on. When I want to warm the food contents, I boil a pot of water and then place the uncovered glass jar in the pot once the water is boiling hot. Then I just stir the food content to distribute the heat evenly. I've been using these jars for about 4 months now and they've worked well.
