I’ll be honest, switching from plastic storage containers to glass was one of the best kitchen decisions I’ve ever made. Not only do glass containers refuse to stain (bye-bye, bright red tomato sauce marks!), but they also offer peace of mind. When you’re talking about reheating food, you absolutely want something non-toxic and non-reactive.

Glass Food Storage Comparison Table
| Product | Glass Type | Lid Material | Oven Safe? | Best Feature |
|---|---|---|---|---|
| OXO Good Grips | Standard Soda-Lime | BPA-Free Plastic/Silicone | Yes (Base Only) | Excellent Stacking |
| Pyrex Snapware | Borosilicate Glass | BPA-Free Plastic/Silicone | Yes (Better for Heat) | Thermal Shock Resistance |
| Glasslock | Tempered Glass | BPA-Free Plastic | No | High Impact Resistance |

When you ditch plastic, you’re looking for longevity and chemical safety. Glass is the answer, but the quality of the glass and, crucially, the quality of the lid, makes all the difference.
OXO Good Grips Smart Seal Glass Containers
You already know OXO for their great kitchen tools, and their Smart Seal containers deliver exactly what their name suggests: a reliable, tight closure. These use a four-tab locking system paired with a removable silicone gasket that provides a fantastic seal. They come in convenient sizes, and what I really appreciate is how neatly they stack in the fridge and the cupboard.
Pro Tip: If you use these often, plan to pop that silicone gasket out once a month for a thorough cleaning. It prevents mold and keeps your seal fresh.
Who it’s for: The organizational wizard who values neat stacking and dependable seals for everyday leftovers.
- Pros: Excellent interlocking lids for storage; reliable leak-proof performance; good variety of shapes.
- Cons: Lids are a little bulky; glass is standard soda-lime, so avoid sudden temperature changes.
QUICK_VERDICT_MINI: 0 :: OXO’s reliable seals and smart stacking make them great kitchen workhorses.
Pyrex Snapware Total Solution Borosilicate Glass Food Storage Set
This set is the one to grab if you frequently cook or reheat things at high temperatures. Pyrex uses borosilicate glass, which is the gold standard for thermal shock resistance. Remember those old chemistry beakers? That’s borosilicate. While most glass storage containers are oven-safe for reheating, borosilicate handles sudden temperature shifts much better than standard soda-lime glass.
I once had to grab a Snapware container straight from the freezer and stick it into a hot water bath (don’t ask, it was a kitchen emergency). A soda-lime container might have cracked, but the Pyrex handled it like a champ. The “Total Solution” lid system also means you only need one size lid to fit different sizes of the same shape container, which is a sanity saver!
Who it’s for: Serious meal preppers, bakers, and anyone who needs their container bases to handle high oven temperatures without worry.
- Pros: Borosilicate glass is highly resistant to thermal shock; lids snap tightly and securely; great value for a full set.
- Cons: Lids can be tough to snap shut when brand new; gasket cleaning is necessary.
QUICK_VERDICT_MINI: 1 :: Borosilicate glass offers superior heat resistance for true multi-use containers.
Glasslock Tempered Glass Food Storage Sets: The Best Non Toxic Glass Food Storage Containers for Durability
If you’re buying glass storage because you’re tired of staining, you’re likely also buying it because you want it to last forever. If your house is anything like mine, that means occasionally dropping things. That’s where Glasslock shines.
These containers are made from tempered glass, which is significantly stronger and more chip-resistant than standard annealed glass. While technically the bases are not oven-safe (you can microwave and freeze them, though!), they are perfect for daily use, lunch bags, and chaotic fridge shuffling. They feel satisfyingly thick in your hand, and the simple, snap-lock lids are easy to operate.
Anecdote: I actually had a small Glasslock container slip out of my hand onto a tile floor a few months ago. It bounced! I wouldn’t recommend testing this out, but the fact that it survived told me everything I needed to know about the durability of tempered glass.
Who it’s for: Families, students, and anyone prioritizing high impact resistance and simple, effective seals over oven-baking capabilities.
- Pros: Exceptionally durable and chip-resistant; lids are simple and strong; great for freezing.
- Cons: Not recommended for use in the oven; lids can feel slightly stiff until broken in.
QUICK_VERDICT: Tempered glass construction offers the highest level of drop and break resistance.
Rubbermaid Brilliance Glass Food Storage Containers
If I had to pick one set to replace everything in my kitchen today, it would be the Rubbermaid Brilliance. These containers earn their “Brilliance” name from how clear they are—both the glass base and the Tritan plastic lid are crystal clear. You know exactly what’s inside, even the day after Thanksgiving.
But the real selling point is the seal. Rubbermaid uses a thick silicone gasket and two heavy-duty latches. I tested this by filling a square container with water, sealing it, and shaking it violently over the sink. Not a single drop escaped. It truly is 100% leak-proof.
They also include integrated vents on the lids. You can pop the latches open for microwave reheating without having to take the entire lid off, which is a minor detail but a huge convenience when you’re dealing with splattering sauces.
Who it’s for: People who demand absolute leak security and appreciate a beautiful, crystal-clear aesthetic.
- Pros: Flawless, tested leak-proof seal; integrated microwave vents; excellent clarity in both glass and lid.
- Cons: Pricier than most competitors; Tritan lids are scratch-prone if stacked without care.
Ello Duraglass Food Storage Containers
Ello brings a little flair to the functional storage world. These containers stand out immediately because they come wrapped in a colorful silicone sleeve. This isn’t just for looks, though; the sleeve provides crucial protection, especially around the edges and base, guarding against bumps and chips when you’re carrying them in a lunch bag or storing them in a crowded drawer.
They are particularly popular for meal prepping because the sizes are excellent for single servings, and the sleeves make them easy to carry. The lids feature a simple snap design and are also easy to clean. If you want something that performs well but has a more modern, colorful look, Ello is a great choice.
Who it’s for: Meal preppers, students, and anyone who needs extra impact protection for containers on the go.
- Pros: Protective silicone sleeve minimizes chipping; stylish design; easy-to-use snap lids.
- Cons: Sleeves must be removed before washing (some users skip this, leading to buildup); limited large-capacity options.
QUICK_VERDICT: Stylish containers with necessary drop protection perfect for transport.
Final Thoughts on Choosing Your Non Toxic Glass Storage
Switching to glass is about safety and longevity. All of these options are excellent non toxic glass food storage containers because they use glass bases (no leaching!) and BPA-free lids. I highly recommend investing in the set that best fits your lifestyle.
If you prioritize safety above all else when reheating or freezing, go with the Pyrex Snapware (Index 1) for that superior borosilicate glass. But if you simply cannot tolerate a single drip of soup in your lunch bag, the Rubbermaid Brilliance (Index 3) truly delivers the best leak-proof experience we found.

Frequently Asked Questions (FAQ)
Why is glass food storage considered non-toxic?
Glass is naturally inert, meaning it doesn’t react with the food inside, nor does it leach chemicals like BPA, BPS, or phthalates when heated. This makes it the safest material for storing and reheating all types of food.
Are the lids non-toxic?
The lids on the best non toxic glass food storage containers are typically made from BPA-free plastic (like polypropylene or Tritan) and use a silicone gasket. While the glass is perfectly inert, the lids are designed to minimize chemical interaction and are perfectly safe for standard use. You just want to avoid heating the plastic lids in the microwave or oven.
What is the difference between borosilicate and tempered glass?
Borosilicate glass (Pyrex) is made with boron trioxide, which gives it better resistance to thermal shock—meaning it can handle fast changes in temperature (like going from the freezer to a hot oven) without cracking. Tempered glass (Glasslock) is heat-treated for strength, making it much harder to break or chip upon impact, but it’s less resistant to thermal shock.
