Product Insights
The Duralex Square Bowl With Lid is a tempered glass bowl that resists thermal shock of at least 130°C, breaking into non-sharp granules, and is free of BPA, lead, and cadmium. Its stackable design allows nesting with lids on for efficient fridge storage. Since 2024, Duralex operates as a worker-owned cooperative, with Origine France Garantie and EPV labels and 99% domestic raw materials. The design is MoMA-featured and used in Michelin-starred kitchens, with users reporting decades of daily use without degradation. The 610 ml bowl suits single servings and is versatile for prep, serving, and storage. However, the BPA-free plastic lid lacks a silicone seal, so it is not leak-proof for liquids and best for dry or semi-solid foods.

Deep Research
Made in France: Duralex's glassmaking history
- After a recent restructuring, Duralex is now a worker-owned cooperative, so purchasing this bowl directly supports a democratically-managed French factory—a rare model in the housewares industry that adds a layer of mission-driven resilience to the brand's heritage.
- Duralex designs are sold in the MoMA Design Store and used in Michelin-starred kitchens, so this bowl shares its functional-minimalist DNA with pieces recognized as design objects—a cultural cachet that elevates it beyond typical food storage.
- All Duralex products, including this bowl, carry the Origine France Garantie stamp, which requires at least 50% of added value to come from France—and with 99% of raw materials sourced domestically, this bowl is genuinely French-made from raw material to finished product, not simply assembled or designed in France.
- In 2019 Duralex earned the EPV label, a French state distinction for companies that have maintained exceptional artisanal or industrial know-how, placing this bowl's century-old tempering technique alongside the heritage crafts of France's most esteemed luxury houses.
- Duralex was created in 1945 by Saint-Gobain specifically to turn the newly invented tempered-glass process into consumer tableware, so the thermal-shock resistance of this bowl comes from the same 700°C-quench method that first made French canteen glasses famously unbreakable.
Why Duralex tempered glass lasts decades
- The tempering process makes the glass at least 2.5 times more resistant to mechanical stress than standard annealed glass, meaning this bowl tolerates accidental bumps, knocks, and utensil strikes that would chip or shatter ordinary glass containers.
- When tempered glass does break, it fractures entirely into tiny, non-sharp granules rather than dangerous shards — much like automotive safety glass — making an accident with this bowl significantly safer for bare feet and hands.
- Duralex heats each bowl to approximately 650°C then rapidly cools it with forced air, a tempering process that gives the glass a thermal shock resistance of at least 130°C — it can survive a sudden 130°C swing, such as moving straight from a freezer at -20°C into a boiling-hot microwave environment, without cracking.
- Because the glass is non-porous, it won't absorb food stains, odors, or bacteria even after years of heavy use; a bowl that held marinara tonight won't carry its ghost into tomorrow's cereal.
- Duralex’s factory in La Chapelle-Saint-Mesmin was the first in the world to manufacture tempered glass tableware (1945), and the company’s tempered glass technology is still considered unique — buying this bowl connects you to an 80-year lineage of French glassmaking that is now worker-owned and globally recognized.
Non-porous glass and food hygiene
- Tempered glass resists odor and stain absorption entirely — even strong foods like curry or tomato sauce won't leave a lasting smell or discoloration after dishwashing, a clear advantage over plastic containers where lipid-soluble molecules can permanently embed.
- Using glass for microwave reheating avoids the microplastic shedding documented with plastic containers; researcher Cassandra Rauert notes that her lab studies show plastic containers shed plastics into the food inside them when heated, so this bowl offers a safer alternative.
- The tempering process gives the glass a specific break pattern: upon extreme impact, it crumbles into small, rounded fragments rather than sharp shards, significantly lowering injury risk compared to ordinary glass — a safety feature inherent to tempered glass.
- Because the surface is smooth and nonporous, thorough cleaning in a dishwasher leaves no microscopic crevices for food residues to accumulate; as food scientist Senaka Ranadheera explains, you can clean it properly so there’s no residues that those microorganisms can hide inside, making glass a more hygienic choice than scratched plastic.
- The tempered glass surface is fully nonporous, so liquids and food particles cannot soak in; unlike plastic, which develops micro-scratches that trap bacteria, this bowl remains sanitary after extensive use because there is no absorptive substrate for microbial growth.
- The glass is chemically inert and free of BPA, phthalates, lead, and cadmium, meaning it won't leach substances into food even with acidic dressings or fatty reheated meals — the FDA classifies glass as a GRAS (generally recognized as safe) food-contact material.

IKEA or Duralex. Not sure either has *rubber* lids, but they have good lids for fridge storage. I think Anchor Hocking makes a series with rubber lids.

User loves Duralex glass bowls for their durability and stackability
I love my Duralex glass bowls. So incredibly durable and they stack! If you're looking for something more decorative, I've started collecting the Fattoria mixing bowls from Casafina. I use them for basically everything from prep to serving.

User reports 23 years of daily use with Duralex glass bowls, still perfect
I've had a set of 9 Duralex glass bowls ($28) for 23 years. Use them every day, and they're still perfect. They are sturdy enough to mix/cook in but styled well enough to look good on the dinner table. Among my top half-dozen best buys ever.
