Are Pyrex Lids Heat Proof?

Are Pyrex lids heatproof? Probably not. As the name suggests, these glass containers are not designed to handle high temperatures and should be used only for storage or refrigeration. However, that doesn’t mean you can’t use your Pyrex lids as a steamer or saucer. You just need to know how to make them heat proof first. The good news is that you can use almost any type of lid with a Pyrex container! Even if a lid is not specifically made for this type of glassware, there are ways to make it work for you. Below, we’ll take a look at some of those methods so that you can safely store food in your Pyrex dish.

Why are Pyrex Lids not Heat Proof?

Pyrex glassware is made from Borosilicate glass, which is an extremely heat-resistant material. However, it can still break if exposed to high temperatures over long periods of time. For example, if you put a Pyrex lid in the oven at 350°F, it will not break or crack immediately. However, it will absorb the heat and continue to build up inside the glass over time. This makes the Pyrex lid very dangerous to use in high temperatures and over long periods of time because it can cause it to break or melt under the extreme temperature. The same thing goes for microwaves. Glass is an insulator, so the heat will not be distributed evenly when you put a Pyrex lid in the microwave. Eventually, the heat will build up inside the glass and cause it to break or melt. Because of this, it’s important to use the correct lid for each container. Otherwise, you risk melting the glass and ruining your Pyrex lids.

Using a Pyrex Lid as a Steamer

If you want to use your Pyrex lid as a steamer, you’ll need to make sure that it’s big enough to fit over the bowl. Some Pyrex lids are smaller than others, so if you’re not sure which to use, it’s safest to go with the largest one. Before putting your lid in the microwave, make sure you place a bowl or plate underneath it to catch the water. This will prevent your microwave from getting damaged and make cleanup easier. For best results, put about 1/2 cup of water in your bowl and cover it with your lid. Make sure you’re using a bowl that is microwave safe because Pyrex bowls are not. Once the water has come to a boil, reduce the heat and let it sit for 5 minutes.

Using a Pyrex Lid as a Saucer

If you want to use a Pyrex lid as a saucer, you’ll need to remove the lid and place the glass underneath the container. You can also use a plate if you don’t have an extra lid lying around. Once you’ve done this, put the food you want to serve on top of the saucer to prevent your plate from getting dirty. Make sure the plate is large enough to cover the entire container so that it doesn’t fall into the food. If you’re worried about the container moving while you’re trying to serve it, you may want to put rubber mats under the container. This will keep the container from moving and sliding around while you’re lifting it.

Using a Metal lid with Pyrex Glass

If you want to use a metal lid with a Pyrex container, you’ll need to line the underside of the lid with foil. This will prevent the Pyrex from melting or coming into contact with the metal. However, don’t line the top of the lid as this will prevent the lid from fitting properly on top of the container. Once you’ve lined the underside of the lid, you can use it with any glass container. This includes your Pyrex containers and any other type of glassware. However, keep in mind that this method will work best with smaller lids. If the lid is too big, you won’t be able to line the underside with foil.

Can You Use a Pyrex Lid in the Microwave?

Yes, you can use a Pyrex lid in the microwave. However, you’ll need to line the underside of the lid with foil to prevent the Pyrex from melting. Make sure the foil is long enough to cover the entire underside of the lid so that it doesn’t fall off. Once you’ve done this, you can use your lid to cover containers and bowls. This will prevent the food from splattering and make cleanup easy. However, you should avoid putting the lid in the microwave for longer than a minute. This will prevent your Pyrex lid from overheating and melting.


Containers and lids are supposed to be used for storage and refrigeration only. While it’s possible to use a Pyrex lid as a steamer or saucer, it’s not recommended. This is because the high heat can damage the glass and cause it to break. The best way to use a Pyrex lid is to use it as a cover. That way, it will protect your food from splattering throughout your microwave or bowl and make cleanup a breeze. If you’re looking for a more convenient way to cover your containers, check out snap-on lids. These lids are made for containers and bowls of all sizes and fit most standard containers. With these lids, you can cover and store food without lifting a finger.
