We also preferred glass and plastic sets that had interchangeable lids among containers, so finding the right lid will be a little easier. We didn’t eliminate round shapes, though, because they can be good for liquid foods. We tried to pick sets with a good range from large to small, with emphasis on rectangular or square space-saving shapes. And the shapes and sizes will affect how easy it is to store containers-square or rectangular containers will maximize fridge or freezer space. Easy to stack and store: Containers that can nest or stack neatly will be easier to store and nicer to look at.And we avoided lids that had microwave vents they’re just another piece to de-crud, and you’re better off removing the latches and resting the lid on top of the container in the microwave (or not using the lid at all, as some manufacturers suggest).

For easier cleanup, we preferred containers that had sealing lids with removable gaskets because you can remove and wash them separately (this also prevents mold buildup).

(This is why tempered glass is used for side and rear windows in cars and glass shower doors.) To understand more on how and why this seemingly random breakage occurs, you can check out our blog post on the subject. That being said, tempered glass is often referred to as “safety glass” because when it does break, it crumbles into cube-shaped pieces that are easy to sweep up, as opposed to long, thin shards that can more easily cut you. Tempered glass does have one downside, however: On rare occasions, it can shatter unexpectedly (this may seem spontaneous, but it’s usually a result of thermal shock or repeated stress on the glass). It can survive being dropped on the floor, and it’s able to withstand dramatic temperature changes without cracking. Tempered glass is ideal for cooking and storing food because it’s very durable. Most glass food-storage containers, including the Pyrex and Glasslock sets we recommend, are made of tempered glass, a type of heat-treated soda-lime glass.

Containers are made from different types of glass, which will affect their durability, price, and how they’ll break if you drop them.
