Is borosilicate glass better than regular glass for food storage?

Yes, for temperature swings. Borosilicate expands less when heated, so it is less likely to crack going from freezer to microwave. Standard tempered glass is tougher against impact but less forgiving of sudden heat.

Can these containers go from the freezer straight to the microwave?

The borosilicate glass is made for that kind of transition, and the set is listed as freezer and microwave safe. Let frozen jars sit briefly if the food is solid, and avoid putting a cold jar on a hot burner or grill.

Are the lids leak-proof?

Glasslock lids seal well for fridge and pantry storage and gentle transport. They are not meant for shaking liquids or carrying soup in a bag, and the seal is the part most likely to wear out first.

Are they dishwasher safe?

Yes, the glass is dishwasher safe. Washing lids on the top rack or by hand helps the seals last longer.

How much food does each jar hold?

Each jar holds about 26 ounces, roughly three cups. That is a good single or double portion for leftovers, soup or dry goods.

How does this set compare with plastic storage containers?

Glass costs more and weighs more, but it does not stain, hold odors or absorb colors, and it can go in the microwave and oven-safe use cases where plastic cannot. Plastic is lighter and cheaper for lunch bags and kids.
