Duralex Le Gigogne Clear Glass Mug, 22 cl (7 3/8 oz), set of 6

1. What touches your drink 45% of the rating 5 of 5

   Only glass touches your drink and mouth: a tempered glass mug with no lid, paint or print.

2. Independent testing 20% of the rating 4 of 5

   Lead Safe Mama's January 2026 mug list links an Amazon set of this mug's size and shape as repeatedly X-ray tested and lead-free, but it publishes no figures for it.

3. Durability 15% of the rating 3 of 5

   Tempered to resist chips and sudden temperature changes, but we found no warranty (only a 10-day claim for damaged or defective orders), and a chipped mug should be thrown away.

4. Trust 10% of the rating 4 of 5

   The maker states glass type, lead and cadmium freedom and care limits and sent samples for testing; no recall or Prop 65 notice, though both stockists we found are third-party sellers.

5. Value 10% of the rating 4 of 5

   $36 for six is about $6 a mug, far less than a travel mug.

• Independent Lead Safe Mama, LLC (independent advocate; earns Amazon affiliate income) January 2026

  Its January 2026 mug list says the exact products shown, or similar ones from the same brand, have been repeatedly tested with XRF and found lead-free, and chosen because they carry no decoration. Its third Duralex item, a set of six clear mugs of 7.4 oz, links the Amazon listing described above, which matches this mug's size and shape. The list names no model and publishes no figures.

• Independent Lead Safe Mama, LLC (independent advocate; earns Amazon affiliate income) June 2020

  A clear Duralex Cosy mug (a different, larger model) read non-detect for lead, cadmium, mercury, arsenic and antimony by XRF, with barium at 2,183 ppm. Open ↗ (opens in a new tab)

• Independent Lead Safe Mama, LLC (independent advocate; earns Amazon affiliate income) January 2018

  Gigogne colored glass ice cream cups, from the same collection, were sent by the maker in 2014 and read negative for lead, mercury and arsenic by XRF (published 2018). They are colored glass, not this clear mug. Open ↗ (opens in a new tab)

Which mug did Lead Safe Mama actually test?

Its published figures are for the Cosy mug, which the maker now lists as final sale and out of stock, and for colored Gigogne ice cream cups. Its January 2026 mug list (opens in a new tab) says it repeatedly tested the exact products shown or similar ones from the same brand, and its set of six clear 7.4 oz Duralex mugs links an Amazon listing for a handled 0.22 L cup that looks like this mug. It does not name the model or give figures, so we scored testing 4 rather than 5.

Does the barium in the Cosy mug matter?

Lead Safe Mama's 2020 reading of the Cosy mug found barium at 2,183 ppm and titanium at 115 ppm. Its owner replied that both are common in glassware, that she has no concern in this use and that she knows of no regulatory limits (post comments (opens in a new tab)). Its 2014 Picardie samples were negative for barium, so it varies by piece.

Is glass better than steel for hot coffee or tea?

Lead Safe Mama says it prefers clear lead-free glass mugs for coffee because heat and acid may release nickel or chromium from steel, while saying it has no science to back that concern (post (opens in a new tab)). Our water bottle guide found steel leaches more nickel into acidic liquids. Duralex says the glass suits hot or cold drinks (maker (opens in a new tab)).

Can tempered glass shatter?

Duralex says its glass is about 2.5 times stronger than ordinary glass, shatters into small pieces if broken by a strong shock, and takes temperature extremes of -4°F to 266°F (maker (opens in a new tab)); the Amazon and Target listings say 212°F. It says not to use a chipped piece or expose it to a sudden temperature change over 130°C, and its UK site says the glass is soda-lime, not borosilicate. Readers of Lead Safe Mama's mug posts ask about reports of tempered glass breaking in cabinets and microwaves; its owner says on the mug list (opens in a new tab) that she has never had a glass mug break from hot water and warms the mug first. Those are anecdotes, and we found no recall.

Has Duralex had a recall, a Prop 65 notice or a lawsuit?

We found no CPSC recall under the Duralex name (CPSC search (opens in a new tab)), no Prop 65 notice naming it (California AG search (opens in a new tab)) and no class action in a web search. The maker says its glassware is lead and cadmium free and BPA free.

Old French glass has had lead. Is this one safe?

Lead Safe Mama read 223 ppm lead in a vintage French Arcoroc tumbler (post (opens in a new tab)). Its tests of new clear Duralex glass were clean; buy new and skip decorated pieces.

• Only glass touches your drink: a tempered glass mug with no lid, paint or print.
• Lead Safe Mama's X-ray tests of other Duralex glass, including a clear mug and colored Gigogne ice cream cups, found no lead, mercury or arsenic (and, for the mug, no cadmium), and its 2026 list links a mug of this size as repeatedly tested.
• About $6 a mug, made in France per the maker, and fine for hot drinks per the maker.

• No figures are published for this exact mug; the evidence is for other Duralex glass plus a list that links this mug without naming it.
• No lid or insulation, so it is for a table, not a commute.
• Tempered glass still chips and breaks; we found no warranty, and the maker says not to use a chipped mug.
• Both stockists we found are third-party sellers on Target and Amazon; the maker's own site also sells it.
