Glasslock 18-Piece Set Review (2026)
In-depth review of the Glasslock 18-piece set: oven-safe tempered glass, four-hinge locking lids, and whether it is the best bake-and-store set.
Glasslock Glasslock Oven Safe Container Set, 18-Piece
The cook-and-store set: tempered glass boxes with four-hinge locking lids that go in the oven, so one dish covers baking and storing.
Our verdict
The Glasslock 18-piece set is the best bake-and-store container set here, because it removes the transfer step between cooking and storing. Tempered glass bases go in the oven, so a casserole can be baked, covered, and refrigerated in the same dish, and four-hinge locking lids seal firmly enough for transport. Glass weight and hinge care are real caveats, but for cooks who hate washing a baking dish and a storage box for one meal, no rival is as practical.
What we like
- Tempered glass bases are oven safe, so leftovers can be baked and stored in the same container with no transfer step.
- Four-hinge locking lids with a silicone seal close firmly and resist leaks far better than press-on lids.
- The assorted rectangular and round shapes pack a fridge shelf efficiently and cover most leftover sizes.
What to watch out for
- Glass bases are heavy, so a full set in one bag is a load, and the boxes need careful stacking to avoid chipping rims.
- Locking lids have hinges and seals that need washing and drying thoroughly to stay odour free.
- The glass is heat tolerant but not unbreakable, so thermal shock from extreme temperature swings should be avoided.
Who it is for
Cooks who bake and store in the same dish and want locking lids they can trust on the way to work or a gathering.
One dish from oven to fridge
The oven-safe glass base is the core benefit. Food can be baked, served, covered with the locking lid, and refrigerated without decanting, which saves washing and keeps portions intact. Tempered glass handles oven heat and microwave reheating, and because glass does not stain, tomato and curry dishes leave no mark after washing. That combination makes Glasslock the natural set for batch cooking, where the same dish may be baked on Sunday and eaten through the week.
Lids that lock on four sides
Four-hinge lids close with a firm snap on every side, compressing the silicone seal evenly around the rim. That even pressure is why the set resists leaks better than single-tab lids, and why it travels well to work or potlucks. The hinges and seals need washing and full drying to stay odour free, but that small habit is the price of a genuinely transport-safe glass box.
How it stacks up
Against Pyrex Simply Store, Glasslock wins on locking lids and oven use, while Pyrex wins on simplicity and outlay. Against FineDine, Glasslock wins on oven versatility and shape range, while FineDine wins on meal prep portioning. Against Rubbermaid Brilliance Glass, Glasslock wins on oven safety, while Brilliance wins on lid familiarity for existing Brilliance owners.

Questions, answered
Can Glasslock lids go in the oven?
No, the plastic lids must be removed before oven use, even though the glass bases are oven safe. Bake with the base uncovered or with a suitable oven-safe cover, then fit the locking lid once the dish has cooled enough to handle.
Is Glasslock glass unbreakable?
No, tempered glass is stronger than ordinary glass but can still break from a hard drop or extreme temperature shock. Avoid moving a dish straight from a hot oven to cold water, and handle rims carefully when stacking.
Do the locking hinges wear out?
Hinges last well with normal use, but forcing a lid or washing at very high heat can weaken them over time. Close hinges evenly on all sides rather than snapping one side repeatedly, and dry the seal fully after washing.
