Soda-Lime or Borosilicate? The Best Baking Dish Glass

Most glass baking dishes look alike on the shelf: clear, rectangular, two handles. The difference is in the glass itself. Some makers use tempered soda-lime glass, some use borosilicate, one on this page uses white opal glass, and each one writes its own rules about heat, cold and the freezer. Those rules decide whether a pan of enchiladas can go from the fridge into a hot oven, or whether it needs to sit on the counter first.

Our main baking dish guide compares glass, ceramic and metal side by side. This page stays with glass and sorts it by brand and by glass type, with each maker’s care rules quoted as the maker gives them. None of the seven dishes below is a pick on the main guide or on our lasagna, brownie, lidded dish or pie dish pages; where we chose a brand that appears on those pages, the review says which product it is and why we picked a different one.

Quick verdict: which glass baking dish to buy

The reviews below give each dish’s glass type, temperature range and care rules, and one honest reason to skip it.

Soda-lime or borosilicate: what the glass type means

Glass bakeware sold in the US today comes in two main types, and the maker usually tells you which one you are buying.

Tempered soda-lime glass is what Anchor Hocking makes, and what most American-market Pyrex dishes have been made of for decades. Anchor Hocking explains on its own site that tempering “more than double[s] the mechanical strength” compared with annealed borosilicate, so the dish is harder to break by knocking it. It also says that when tempered glass does break, it “breaks into relatively small pieces” that generally lack sharp shards. The trade-off is heat: soda-lime glass expands more as it heats, so it is more sensitive to sudden temperature changes. That is why Pyrex and Anchor Hocking both tell you not to move their glass straight from the freezer to a hot oven.

Borosilicate glass expands much less with heat. The Museum of Glass in Tacoma describes it as “hard glass” with a low expansion coefficient that resists thermal shock, while soda-lime has a higher coefficient and is more susceptible to it. Simax and Ôcuisine sell their dishes on that point, with stated ranges from -40°F up to 572°F and 662°F. Borosilicate is not unbreakable, though: it can still crack under a fast or uneven temperature change, and it is less resistant to knocks. Pyrex’s own FAQ puts the trade-off plainly: soda-lime resists impact breakage slightly better, borosilicate handles extreme temperature changes slightly better.

Opal glass, the white glass Luminarc calls “culinary opal”, is a tempered glass too. It looks like ceramic but behaves like glass, and Luminarc rates it to 250°C (482°F).

If a listing does not say which glass it is, as with the Pyrex and Libbey dishes below, treat it as you would tempered soda-lime glass and follow the maker’s care rules to the letter.

Our picks for the best baking dish glass

These seven dishes cover tempered, borosilicate and opal glass, from a single 8-inch square to a 5.2-quart roaster, and from one dish to a five-piece kitchen starter set. Each review names the glass type where the maker states it, the temperature range, and the care rules that come with it.

How to choose a glass baking dish

Glass is easy to clean, non-porous and lets you see the food as it bakes. These are the things that separate one glass dish from another.

The glass type, and the rules that come with it

Tempered soda-lime glass is tougher against knocks; borosilicate copes better with fast temperature swings. Neither is foolproof. Read the maker’s rules for the dish you buy: Pyrex and Anchor Hocking say no freezer-to-hot-oven moves, while Simax and Ôcuisine rate their borosilicate from -40°F up to 572°F and 662°F.

The stated oven limit

Anchor Hocking gives 425°F for its tempered glass; Pyrex gives no number and says any temperature a recipe calls for in a fully preheated oven. If you roast at high heat or finish dishes very hot, a borosilicate dish with a stated limit above 500°F gives more room.

Size and depth

A 3-quart, 9 x 13-inch dish feeds most families. Deep dishes, like the Pyrex Deep or the Simax roaster, hold saucy bakes without spilling over. Two people do well with a 2-quart or 8 x 8-inch dish.

Lids and what they are for

Most lids sold with glass dishes are plastic and stay out of the oven. A glass lid, like the Simax’s, can bake covered. If you need a lid that latches for the car, see our guide to baking dishes with lids.

Safe handling habits

Whatever the glass, the makers agree on the basics: put the dish in a fully preheated oven, keep it off burners and out from under the broiler, add a little liquid before baking foods that release juice, and set the hot dish on a dry trivet or towel, never a wet counter or a cold stone surface. Discard glass that is chipped or cracked.

How we picked these seven glass dishes

We looked at glass baking dishes from Pyrex, Anchor Hocking, OXO, Libbey, Simax, Ôcuisine, Luminarc, Borcam, Crystalia and Amazon Basics, along with a range of anonymous Amazon-only sellers. We left out every dish already picked on our main baking dish guide, our lasagna dish guide, our brownie pan guide, our lidded dish guide and our pie dish guide. That ruled out OXO entirely, since both of OXO’s glass dishes are picks on the main guide. We passed on anonymous brands and on Amazon Basics, and kept only dishes that showed as in stock on Amazon when we checked.

We stopped at seven. Other in-stock glass dishes we found were either near-duplicates of these, already picked elsewhere on the site, or from sellers we could not identify.

Specifications come from each maker’s Amazon listing, Anchor Hocking’s FAQ and “why choose glass” pages, and Pyrex’s FAQ and safety and usage instructions, each named where we use it. Background on borosilicate and soda-lime glass comes from the Museum of Glass in Tacoma. We searched the US Consumer Product Safety Commission’s recall site for each brand and found no recall covering these dishes. We have not used these dishes for this guide.

Glass baking dish questions, answered

What is the best glass baking dish brand?

It depends on the glass you want. For tempered glass, Anchor Hocking and Pyrex are the long-standing American brands; Anchor Hocking states made in the USA on our pick. For borosilicate, Simax (Czech Republic) and Ôcuisine (France) both state the glass type and a wide temperature range.

What makes a best quality glass baking dish?

A maker that states the glass type, a clear temperature range and full care instructions, plus a warranty if you can get one. Thick, even walls and handles big enough to grip with oven mitts matter in daily use.

Is borosilicate glass better than tempered glass for baking?

Better for sudden temperature changes, according to the makers and the Museum of Glass, but not for knocks. Anchor Hocking says tempered glass is stronger mechanically and breaks into smaller pieces. Choose by how you cook.

Can a glass baking dish go from the freezer to the oven?

Not Pyrex or Anchor Hocking glass; both say to thaw first. Simax and Ôcuisine rate their borosilicate from -40°F, but a preheated oven and some care are still sensible.

Can I put a glass baking dish under the broiler?

No for Pyrex and Anchor Hocking, which both say so in their care guidance. If you want to brown cheese on top, use a broiler-safe ceramic or metal dish.

The glass dish to start with

Buy the Anchor Hocking 2-piece set if you want everyday tempered glass in two sizes. Choose the Simax roaster if you move dishes from fridge to oven, and the Ôcuisine set if you cook for a crowd.
