Why Choose Glass Over Plastic Food Storage
Glass food storage containers have surged in popularity as consumers become increasingly concerned about the potential health risks associated with plastic. Unlike their plastic counterparts, glass containers don’t leach chemicals into food, particularly when heated. They’re also environmentally friendly, as high-quality glass containers can last for years or even decades with proper care.
The non-porous surface of glass means it won’t absorb food odors, flavors, or stains. This makes glass containers particularly valuable for storing aromatic foods like curries, tomato based sauces, and strong spices. You’ll never again have to worry about yesterday’s spaghetti sauce leaving behind both a red stain and a lingering smell.
Glass containers preserve food freshness while allowing you to easily see what’s stored inside

Comprehensive Buying Guide for Glass Food Storage Containers
Material & Safety Considerations
When shopping for glass food storage containers, you’ll encounter two primary types of glass: borosilicate and tempered soda lime. Borosilicate glass contains boron trioxide, making it more resistant to thermal shock the stress that occurs when glass experiences rapid temperature changes. This means borosilicate containers can typically go directly from freezer to oven without cracking. However, they tend to be more brittle and may shatter more easily when dropped.
Tempered soda lime glass, on the other hand, undergoes a special heating and cooling process that increases its strength. While these containers are less resistant to thermal shock than borosilicate, they’re more durable against physical impacts. If they do break, they shatter into small, dull pieces rather than sharp shards, making cleanup safer.

Durability & Leakproofness
The durability of glass containers depends not only on the type of glass but also on their design and construction. Look for containers with thick, sturdy walls and reinforced edges that can withstand regular use. Some premium models feature silicone sleeves that provide additional protection against bumps and drops.
Leakproofness is primarily determined by the lid design. The most secure lids feature silicone gaskets that create an airtight seal, often combined with locking mechanisms that clamp down on all sides. This prevents spills when transporting soups, sauces, or other liquids. Some containers also have venting mechanisms for microwave use, allowing steam to escape without removing the lid entirely.
Versatility (Oven, Microwave, Freezer, Dishwasher Safety)
The best glass food storage containers offer versatility across different environments. Most glass containers are naturally microwave safe, but always check manufacturer specifications. Oven safety varies significantly some containers can withstand temperatures up to 950°F, while others are limited to 450°F or aren’t oven safe at all.
Freezer compatibility is standard for glass containers, though you should leave adequate headspace (about 1-1.5 inches) when freezing liquids to allow for expansion. For dishwasher safety, glass containers are generally fine on any rack, but plastic lids should typically be placed on the top rack to prevent warping.
| Glass Type | Oven Safe | Thermal Shock Resistance | Impact Resistance | Typical Max Temperature |
| Borosilicate | Yes | Excellent | Moderate | Up to 550°F |
| Tempered Soda-Lime | Yes | Good | Better | Up to 450°F |
| Untreated Soda-Lime | Limited | Poor | Poor | Up to 350°F |
Lid Types and Sealing Mechanisms
Lids are a crucial component of any food storage container system. Most glass containers come with plastic lids, though some premium options offer glass lids with silicone seals. Plastic lids are lightweight and less prone to breakage, but they can’t be used in ovens and may retain odors over time.
Common sealing mechanisms include:
- Snap lock lids: Feature latches on multiple sides that click into place, creating a secure seal
- Pressdown lids: Use pressure to create a vacuum-like seal with a silicone gasket
- Screw top lids: Less common but provide excellent leakproofing for liquids
- Silicone stretch lids: Flexible covers that stretch over container tops (often sold separately)
Some containers feature removable gaskets for thorough cleaning, while others have permanently attached gaskets that are easier to use but may trap food particles over time.
Shape, Size, and Storage Efficiency
Glass food storage containers come in various shapes and sizes, each suited to different purposes. Round containers are ideal for soups and stews, while rectangular or square containers maximize space efficiency in refrigerators and freezers. Consider how the containers will stack both when in use and when empty.
Most sets include a range of sizes from small (perfect for dressings or small portions) to large (ideal for family meals or batch cooking). The most versatile sets offer containers that nest inside each other when not in use, minimizing the storage space required.
Efficient storage is possible with containers that nest when not in use
Ease of Use and Cleaning
The best glass food storage containers balance functionality with user-friendliness. Look for containers with wide rims that are comfortable to hold, especially when hot. Lids should be easy to put on and remove, even for those with limited hand strength.
For cleaning, containers with rounded interior corners collect less food residue and are easier to wipe clean. If the containers have removable gaskets, these should be simple to take out and replace. Some premium containers feature measurement markings, which can be helpful for portion control or recipe preparation.
Value & Sets Available
Glass food storage containers represent a higher initial investment than plastic, with prices ranging from about $3 to $10 per container when purchased individually. Sets offer better value, typically including 5-10 containers with lids for $30-$80, depending on quality and features.
When evaluating value, consider not just the price but the versatility, durability, and warranty. Some manufacturers offer lifetime warranties on their products or replacement lids, which can significantly extend the usable life of your set. Remember that manufacturers count both containers and lids when advertising the number of “pieces” in a set so a 10 piece set typically includes 5 containers with 5 lids.

Frequently Asked Questions
Can glass food storage containers go from freezer to oven?
It depends on the type of glass. Borosilicate glass containers can typically go directly from freezer to oven without issues, as they’re highly resistant to thermal shock. Tempered soda lime glass containers should be allowed to thaw first before heating to avoid potential breakage. Always check the manufacturer’s specific guidelines, as maximum temperature ranges vary from 350°F to 950°F depending on the product.
How do I prevent glass containers from breaking?
To maximize the lifespan of your glass containers, avoid extreme temperature changes (unless using borosilicate glass), don’t place hot glass on cold or wet surfaces, and handle with care when frozen (as glass becomes more brittle at low temperatures). When stacking in cabinets, ensure containers are completely cool and dry to prevent sticking and potential chipping. Some manufacturers also offer silicone sleeves that provide additional protection against bumps and drops.
Are the plastic lids on glass containers BPA free?
Yes, all of the plastic lids on our recommended glass container sets are BPA free. However, even BPA free plastics may contain alternative chemicals that could potentially leach into food when heated. For this reason, we recommend removing plastic lids before microwaving or heating food, regardless of whether the manufacturer states they are microwave safe. If you’re concerned about plastic contact with food, consider sets with glass lids like the Pyrex Ultimate or Bentgo Signature.
How do I remove stains and odors from silicone gaskets?
To remove stains and odors from silicone gaskets, first remove them from the lids if possible. Soak in a solution of warm water and baking soda (about 2 tablespoons per cup of water) for several hours or overnight. For stubborn odors, you can also try soaking in white vinegar or lemon juice. After soaking, wash thoroughly with dish soap and allow to dry completely before reattaching to lids. Some manufacturers also suggest running silicone gaskets through the dishwasher on the top rack for thorough cleaning.
What’s the best way to store glass containers when not in use?
For efficient storage, nest containers of the same shape inside each other, with the smallest at the top. Store lids separately, either stacked flat or in a dedicated organizer. To prevent sticking, ensure containers are completely dry before stacking. For sets with multiple shapes, group by shape to maximize space efficiency. Some premium sets like the Caraway include dedicated storage organizers. To protect glass edges from chipping, avoid overcrowding in cabinets and handle with care when removing nested containers.
