Q&A for How to Use Oven Safe Glass Bakeware

One option you probably haven't tried yet is Bar Keeper's Friend. It's a powder composed of oxalic acid, and it will get almost anything off of bakeware. Just sprinkle the powder over the stain, scrub it with a soft towel or sponge, and rinse the bakeware thoroughly. You really have to get it 100% clean before using it again, since oxalic acid is not safe to consume.

Yes, although I'd mix it in equal parts dish soap and water. I'd rub that into the stain with a sponge and scrub it as needed to wear the residue away.

You're risking a crack this way. Let the dish come to room temperature before putting it in the oven.

No. If carefully read the instructions provided with the Pyrex and use the glass bakeware properly there should be no issues with exploding Pyrex. The only time your Pyrex would break suddenly is if it is exposed to drastic and temperature change (thermal shock).

It is recommended that you carefully read the cooking instructions for the pie crust before baking. Typically pie crusts should be partially thawed before placing in the oven. In order to avoid thermal shock to the Pyrex pie plate make sure the plate is at room temperature and not moving directly from the freezer into the oven.

No. Anchor tops are plastic and will melt at high temperatures.

The foil is probably not enough to protect against freezer burn. Try placing the whole dish in a large Ziploc bag, or wrap the dish thoroughly with plastic wrap. The glass dish is fine in the freezer, just be sure to cool it down thoroughly before putting in the freezer.

Yes, you should. Food can still stick to glass.

Oven safe glass bakeware should not be placed directly in fire and may break if misused. It should only be used in conventional ovens and microwaves.

No. It even says not to use it on a hob on the packaging when you buy a new one. The reason? It will not just shatter but explode, sending glass fragments everywhere.

If you preheat the oven with both the dishes and the sheet inside, it should be safe to do so.

If you heat the glass in the toaster oven as it preheats, it likely won't break. However, the contents will cook very unevenly.

Pyrex is safe up to at least 500°, so there should be no issues. You can also put it directly in the fridge, if desired.

Yes, you can use parchment paper in Pyrex baking dishes as long as the oven temperature is within the recommended range for both the paper and the dish.

Yes, you can use your glass Anchor baking dish in a countertop oven, but ensure it is oven-safe and avoid sudden temperature changes to prevent thermal shock.

It depends on the temperature of both the liquid and the glass. If both are at the same temperature, the risk of shattering is minimized. However, it is always safer to heat the liquid in room-temperature bakeware.

You should generally be safe to put most glass baking dishes into a heated oven, assuming your oven and room are at reasonable temperatures. However, it is advisable to preheat the glass with the oven.
