Question: Can these glasses be used for freezer storage?
Document: I am very pleased with the quality of this set of storage glasses. I want to replace my plastic with glass and am starting here. The glass is thick, the design is nice, the lids fit tight, and they stack well in the frig and freezer.
This is an excellent product at an excellent price. So many uses...drinking glasses, food storage, jelly jars. I have two sets currently and will buy more. I make freezer jelly and jam in the late summer, and these jars are the perfect size for my own use as well as for gift giving. They make my jelly as attractive as it is delicious. Love them
Love these for storing my smoothies in the freezer. Don't want to use tupperware. These work great. Love them and the easy plastic tops that come with them as covers. Great for other storage too.
I got these glasses  because I wanted some smaller storage items to freeze single servings. I have used these glasses several times since I purchased them and found them to be very useful. The glass feels a  bit on the light side (in weight) but they are indeed marked &#34;500&#34; which leads me to believe they will hold  up as the older ones did.
I bought two sets originally to package homemade gifts.The ones left over are in use in my kitchen. Two as drinking glasses. The rest are storage. They work efficiently as leftover storage in a house of two, or other situations where there is enough to keep but not that much.I've marinated veggies for snacks, a single small fish for ceviche, mixed (by shaking) small amounts of salad dressing, used these to layer fruit and yogurt desserts. I even find it a good size for cereal.
I was looking for glass storage jars with a non reactive lid to make my clay slurry in. These work perfectly. The lids can be used as coasters, which is nice if you have a need. I am considering buying more. I'm not sure I have a need for more, I just really like them.
Have used these food storage jars for the past 20 years or more. They have lasted so long, couldn't find them locally. They are the perfect size for leftovers, they are very sturdy, keep the contents fresh, and you can see what is in the jar without opening it. They are microwave friendly (without the top) and dishwasher safe.
Perfect one serving size. Great storage They feel good in your hand, and their style is classic. For the price, you can't go wrong. I've used them for many years, and was happy to be able to find replacements on Amazon. (They're sturdy, but GLASS. Accidents happen!)
Love how I can stack them up in my cupboard that's designated for daily drinkware. Have used them for food storage as well. Lids don't absorb the food fragrances (yet, and I sure hope they never do! ), but I don't microwave them and I also make sure that the food level is such that it doesn't touch the lid. But they get VERY slippery when I wash them.
These glasses look attractive and I serve them for all occasions.I thought they would be just for drinking - not at all! I put leftovers in them and with the tops onthey stay fresh in the refrigerator or the freezer. They are sturdy and strong, do not crack or break easily,go in the dishwasher. i haven't tried them in the microwave yet.
Answer: Yes, with cautions.Leave plenty of headroom for freezing items to expand and don't overfill. Don't change temperatures suddenly. I only put the food in the freezer from room temperature, and I don't heat suddenly.I feel a little more secure with these in the freezer than thinner jars, but a broken glass would not surprise me at all.
