Glass food storage containers — and the lids nobody declares

• “Tested by CPSIA-accredited independent labs to ensure that they are free of BPA, BPS and phthalates” — the lab class is named, the specific lab and report are not. [1] [2]
• PFAS is not addressed either way. [2]
• “Responsibly made in China”, stated. [2]
• The only non-glass container in this category publishing an oven ceiling in degrees: “Containers are oven safe up to 150 degrees C”. Not for microwave, being steel. [2]

• They are the only brand in this entire table that names siloxanes. For a silicone-lidded product that is the relevant residual question and nobody else touches it. [2]
• But their own FAQ says the glass containers are “borosilicate glass”, while this product page says semi-tempered soda lime. Those are different materials with different thermal-shock behaviour. Either the FAQ over-claims or the range mixes both, and the brand does not resolve it. [1] [2]
• The FAQ cites “LFGB-certified silicone seals”; the product page does not repeat it, and no certificate is published. [1] [2]
• “Oven safe but remove the lid” with no temperature ceiling. Made in China, with some manufacturing stated as Australian at brand level. [1]

• It is called “Zero Plastic” and the seal is not disclosed. A glass-on-glass lid still needs a gasket, and Pyrex does not say what it is — which quietly undercuts the name. [1]
• Worth knowing about the Pyrex brand generally: the European product is borosilicate and the US product is tempered soda-lime. They are different glasses under one name, and Australian shelves carry both. [1] [2]
• No warranty, oven rating or dishwasher guidance published on the collection page. [1]

• The gasket is in constant contact with food and it is the one component with no name. That pattern — body named, lid named, seal silent — recurs across the category. [1]
• “BPA free” excludes BPA only. Nothing on BPS, phthalates or PFAS. [1]
• No oven, freezer or microwave guidance at all. The only care line is “Dishwasher safe (top rack only for lids)”. [1]
• No certification, no country of manufacture, no warranty. [1]

• The lid polymer is not named. For a buyer trying to avoid plastic, the lid is the part that matters most, and it is the one part Décor leaves out. [1]
• “BPA Free” is the chemical claim. That excludes one monomer and says nothing about BPS, BPF or phthalates in whatever the lid is made of. [1]
• Décor is an Australian brand and the page does not say where this is made. [1]
• No warranty published. No third-party testing. [1]
• Myer lists it and publishes no material information — not borosilicate, not the silicone seal. The material facts above all come from Décor. [2]

• A 400°C claim with no named glass chemistry is the most aggressive unsupported thermal claim in this category. Borosilicate and tempered soda-lime behave very differently at that temperature and the page does not say which this is. [1]
• “Oven safe (Body only)”, microwave safe, “Dishwasher safe (including lid)”, freezer to −20°C. The guidance is good; the material behind it is not given. [1]
• “Safe and BPA free Tritan lid” — the BPA claim covers the lid only, and Tritan is BPA-free by design. [1]
• No country of manufacture and no certification on the product page. [1]

• The temperature guidance has the same shape: “The lid is microwave-safe; heat food up to 100°C” gives a ceiling for the lid, while “The container is oven-safe, but the lid is not” gives no ceiling for the glass at all. [1]
• No BPA, PFAS or chemical claim of any kind — which is at least consistent with naming the polymers instead of making claims about them. [1]
• No country of manufacture and no certification. [1]
• Its all-plastic sibling is the benchmark for this category: polypropylene body, polypropylene lid, silicone rubber seal, all three food-contact parts named. [2]

• The lid material is not specified beyond being clear and flat-rimmed. The lid is a food-contact part. [1]
• No country of manufacture stated on the product page. Décor is an Australian company and the site references an Australian Made page we could not reach — worth checking, because if it is locally made that is worth two points it is currently not getting. [1]
• No third-party testing published. [1]
• Décor defers to retailers for price, so there is no manufacturer price to quote. [1]

• A leak-proof lid necessarily has a plastic body and a gasket. Neither is disclosed: no polypropylene, no Tritan, no silicone, nothing. [1]
• No BPA statement at all on a plastic-lidded storage set, where “BPA-free” is near-universal marketing. Its absence where the claim would be cheap is worth noting. [1]
• “Oven Safe: Yes” to 400°C is stated for the set. The lid is certainly not oven safe and the page never scopes the claim to the glass. [1]
• The −40°C to 400°C range is asserted with no standard cited. One-year warranty. Country of manufacture not published. [1]

• Pyrex’s Australian distributor publishes the rule outright: “Pyrex® made in the US (Soda-lime glass) and China (Borosilicate glass)” carry a two-year warranty, while “PYREX® made in France” carries ten years. So in Australia a 10-year warranty means French borosilicate and a 2-year warranty means US soda-lime or Chinese borosilicate. [2]
• Their own comparison, verbatim: “Soda lime is slightly more resistant to impact breakage than borosilicate, and borosilicate is more resistant to extreme thermal changes than soda lime.” Neither is better; they fail differently. [2]
• The lid is “BPA free” and its resin is not named. The lid contacts food, so we treat it as a food-contact part. [1]
• No gasket — and they say so: “Non-leakproof product”, “not suitable for transporting liquid foods”. Honest. [1]

• Its own sibling makes the gap obvious. The Glasslock Classic line is explicitly rated −20°C to 120°C. The Oven Safe line, sold alongside it, gives no number at all. [2]
• The base glass chemistry is not published for either line — not soda-lime, not borosilicate. Glasslock’s European site says only “high-quality tempered glass”. [1] [2]
• Lid resin not published. The oven-safe models are distinguished by a red sealing ring whose material is implied to be silicone and never stated. [1]
• “Made in Korea”. The Red Dot, iF and Good Design awards the brand cites are design awards, not materials testing. [2]

• No standard body is cited — no LFGB, no FDA reference, no EC 1935/2004 — so the platinum-cure claim is the maker’s word. [1]
• “Made without BPA or Phthalates” excludes two classes and is silent on PFAS, BPS and residual siloxanes. For a silicone product the siloxane question is the relevant one, and only Seed & Sprout addresses it anywhere in this table. [1] [2]
• The Australian page quotes its temperature ceiling in Fahrenheit only: “Heat Safe silicone can be used in temperatures up to 425° F” — about 218°C. On an Australian site that is a small but real usability failure. [1]

• “BPA-Free Construction: The BPA-free lids provide a general food-safe option”. The lid polymer is never named, and the lid is a food-contact part. [1]
• No seal or gasket material given, despite “an airtight and watertight closure”. [1]

• Not even a BPA claim, which every other Anko plastic-lidded product carries. On this set there is no chemical statement of any kind. [1]
• “Oven safe” and “Microwave safe” appear as unqualified bullets, and the care text then forbids the lid in either. The lid is neither, and the bullets do not say so. [1]
• Twelve pieces means twelve bases. The twelve lids are not counted — unlike the 15-piece plastic set, which does count its lids. [1] [2]
• Target’s sibling $20 five-piece set does carry a “BPA-free” claim, on a product whose only unnamed component is the lid. BPA is irrelevant to glass, so that claim can only be about a plastic the page refuses to name. [3]

• “BPA-free plastic” names one excluded chemical and discloses nothing about what is present — no polypropylene, no resin code, no BPS or BPF statement. [1]
• The glass type is not stated on the Australian-facing listings. Pyrex Europe is borosilicate; Pyrex US is tempered soda-lime. The name does not tell you which you have. [1] [2]

That is one of the broadest exclusions in this table — and it still does not say what the resin is. [2]

• Kmart’s own 13-piece set at $10 sits at the same shelf position and names no polymer at all — only “BPA-free plastic”. Two directly comparable products, two different disclosure standards. [2]
• No lid or gasket material is separately given; the single field covers the whole set. [1]
