I am looking for containers to culture buttermilk in and then freeze. Will these stand up to boiling in water to sterilize them?

You should probably use glass mason jars for that. Or a big stainless steel pot, then pour it into the plastic containers when the buttermilk is cool. I wouldn't put boiling liquid into plastic.

I honestly don't know. I wash them on the upper rack in the dishwasher. I use them for food storage in the freezer and refrigerator. Personally I wouldn't put boiling water into plastic

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack

The containers are designed for use in the refrigerator. We do not recommend using in the freezer.

I do not use bottle warmers. But I have puts frozen pouchs in boiling water and it holds up just fine.I'd imagine you'd be fine.

It will not. They have a silicone outside and cloth inside. You should be fine if you spill something hot on them. I would not suggest immersing them in boiling liquid however!

Yes, they won't shatter and they're glass not plastic so no weird chemicals. I wouldn't recommend handling them too much while they're full of hot liquid or using them to serve hot liquid as they're not insulated at all and the sides get very hot. Typically I just fill mine with hot water and tea and the stick them directly in the fridge to make iced tea.

I haven't tried to put mine in the freezer but I don't see any reason why you couldn't. I use margarine containers in the freezer all of the time. Since we know that the glass is impervious to the cold, the only question would be the lids and they are essentially the same thing as margarine container lids so I don't see why not. Hope this was helpful. P.S. I wouldn't try to pop the lid off right away after taking one out of the freezer but rather wait a couple minutes for it to warm up and become flexible again.

I think so! I microwave sterilize my Dr. Brown's bottles and pacis and my Medela storage containers so I feel confident saying these ones work, too. I just haven't done it myself because I switched to larger storage containers.

Yes, I freeze the bowls and lids all the time. The lids are just plastic, so they'll be fine.

I would imagine so if you have the special attachment lids for the jars. HOWEVER, as an avid canner myself, I would NOT recommend sealing jars of food in this fashion. The hot water bath and/or pressure canning systems do more than merely seal the jars. They kill microbes that would otherwise destroy the food and/or make people ill. This is a good unit for saving leftovers, splitting up frozen foods into smaller quantities, and preserving dried foods. I, personally, would not use it for long-term storage of fresh or wet foods.

Yes!!!! I used these for freezing over 600 oz of breastmilk. I didn't store BM in them long term. Once the milk was frozen, I popped the cubes out and stored either in a vacuum sealed bag (highly recommend this for long term), or a zippy freezer bag. Then they were placed in a deep freeze and some stored for up to 5 months. I never had any problem with milk quality. The vacuum sealed bags make the cubes stick together a bit as they are pressed onto one another, especially when stored for a few months, but a quick smack on a counter top broke them up well.

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.

I have not done that yet. You may want to try it first. I do use these a lot, I just never froze them. Sorry I could not be more helpful.

i have used them in the freezer and also sent them to school with my 4yr old, and they have not leaked or cracked. I make sure they are not filled to the brim and the food is moveable so that they don't explode and keeps the seals in place

I have not tried storing yogurt in these. However, I did put butter in the smallest one, and on a hot day I accidentally left it in the car . . . the butter was melted, but nothing leaked out--and it was on its side!

I would not freeze these bottles. Some glass canning jars are made specifically to withstand freezing. I don't remember anything stating these could be used in the freezer so I wouldn't.Edit: Now that I think about a bit. I did make some infused vodkas that I kept in the freezer without any problems. FWIW

I am not sure about boiling water. They do hold up in Temps of 170 for several hours.
