Pyrex Support

General

What are the benefits of Pyrex® brand products?

A kitchen staple for more than 100 years, Pyrex® glass bakeware can handle almost every job in the kitchen and is versatile enough to use in the refrigerator, freezer, oven, microwave, dishwasher and on the table.

Are Pyrex® products covered by a warranty?

YES - For details, click here to visit our product warranty section.

What is the maximum oven temperature for Pyrex®?

Pyrex® glass bakeware is designed for use in a completely preheated conventional or convection oven at any temperature that is called for in a baking recipe, provided you follow the Pyrex® Safety and Usage Instructions. Remember that Pyrex® glass bakeware is not to be used with any direct heat source such as on the stovetop or under the grill. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Which is better soda lime or borosilicate glass?

As we produce both soda lime and borosilicate glass this means that both materials meet our high-quality standards with over 100+ years of manufacturing experience. Both soda lime and borosilicate are safe for use at any temperature called for in kitchen cooking given the Safety and Usage instructions are followed. Both are suitable for microwave and conventional/convection oven use. Both are dishwasher friendly. Additionally, both materials will not absorb stains or odors. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

What is the difference between soda lime and borosilicate glass?

Soda lime is slightly more resistant to impact breakage than borosilicate, and borosilicate is more resistant to extreme thermal changes than soda lime. They share the same Use & Care instructions and are equally suited for your home cooking needs as long as the Use & Care instructions are followed. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Why does my Pyrex® baking dish have a raised centre?

The raised area in the center of the Pyrex® dish is called a crown and creates a more stable bottom for the dish. If the dish was completely flat on the bottom, it would allow the dish to spin around on a countertop or table. Crowning the inside of the dish makes the outside edges a point of contact and provides a more stable surface for the dish.

Why are the dishes in my set different colours/tints?

You may notice that some of our Pyrex® brand glassware has a slight tint of green or blue hue to the dish. It is not a coating or added colour. It comes from the raw materials in the glass itself. The blue comes from adding cobalt to the raw materials. This does not affect the performance of the dish; it is purely cosmetic.

Are Pyrex® glass products dishwasher safe?

YES - The dishwasher must be properly loaded to avoid items from making contact during the cycle. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Are Pyrex® covers microwave safe?

YES - The cover must be unsealed from the dish and lay off-center to allow steam to escape. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I use my Pyrex® dish on a stove top, under a grill or in a toaster oven?

NO - Do not use Pyrex® glassware on the stovetop (open flame or electric burner), under the grill, in a toaster oven, or on a barbecue. This type of use exposes Pyrex®glassware to potentially damaging direct heat sources. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

If my food becomes dry, can I add liquid to the dish?

NO - Adding liquid to hot glass may compromise the product’s strength, potentially resulting in breakage. Avoid sudden temperature changes. Prior to putting the dish in the oven, add enough liquid to cover the entire bottom of the dish for any foods that may release liquid while cooking such as meats and vegetables. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Where can I place my hot Pyrex® dish when taking it out of the oven?

Place the hot glass dish on a dry cloth, wood or cork trivet, potholder or dry wooden cutting board. To avoid sudden severe temperature changes to the glass, NEVER place hot glass on a cold or wet surface. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

What is the best way to clean baked on food?

Once the dish has cooled to room temperature, we recommend soaking in warm soapy water then using a nylon or plastic scouring pad/scrubby. If more extensive cleaning is needed, we recommend using a non-abrasive cleanser. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I engrave decorative designs and/or writing onto the glass?

NO - Pyrex® glass is not suitable for engraving, etching, etc. Intentionally altering the surface of a product will void its warranty and may subject the product to premature failure. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How do I stretch a cover that is too tight?

Run hot water over the plastic cover for a minute or two (use extreme caution when dealing with hot water). Put the cover on the dish while still wet. Let the cover dry on the dish overnight. The hot water will expand the cover so that it fits and forms to the dish. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How do I get lingering food odours out of a cover?

We recommend soaking in white vinegar overnight then washing with hot soapy water. Please note that as plastic is porous, this method may not remove all of the odour and it may just take time. We do not recommend storing foods with strong odours, such as onion or garlic, in the dish due to this reason.

My cover has warped. Can I straighten it?

NO - Once a cover has warped, there is no way to reshape it. If the cover is within our two-year warranty period, please contact us. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I wash my plastic covers in the dishwasher?

YES - Top Rack only. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can my plastic covers be used in the refrigerator and freezer?

YES - Before placing in the freezer, please make sure to leave some space for the expansion of food contents. After removing from the freezer, let the dish and cover defrost before attempting to remove the cover. Plastic is brittle when frozen and can easily crack. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can my plastic cover go in the oven?

NO - Pyrex® lids comprised of plastic must not be used in conventional or convection ovens because they will melt. Plastic covers are safe for use in the microwave and for food storage. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can my Pyrex® glassware break if it’s dropped, knocked against a hard surface, or struck with a hard utensil?

YES - Always handle your Pyrex® glassware with care. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Should I continue to use my Pyrex® glassware if a piece becomes chipped, cracked or deeply scratched?

NO - The strength of the dish may be compromised causing it to break or shatter (even long after a chip or crack appears). Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How should I clean up my Pyrex® glassware if it breaks?

If you do break a piece of Pyrex® glassware, use protective wear such as thick gloves and a great deal of caution cleaning up the broken glass. Pieces can be extremely sharp and widely spread from the point of breakage. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can my Pyrex® glassware get extremely hot in both conventional and microwave ovens?

YES - So use protective wear such as pot-holders to handle heated glass. Never touch the hot glass with your bare hands, or allow it to come into contact with your body. Keep hot glass well out of children’s reach. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Does my oven need to be preheated when using my Pyrex® glassware?

YES - Always completely preheat your oven to the desired temperature before placing your Pyrex® dish inside it. While the glass is designed for temperatures typically used in baking, it can break when exposed to the direct heating element while the oven is preheating. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How do I cook items that may release liquid (including fat, food juices, or moisture from frozen foods) in my Pyrex® glassware?

Add enough liquid to cover the bottom of the dish before you put it in the oven. This serves to minimize any potential sudden temperature change that may occur as the food releases liquid. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Once a Pyrex® dish is already hot, can I add liquid to it (for example, by basting with liquid not already in the dish)?

NO - Adding liquid to hot glass may compromise the product’s strength, potentially resulting in breakage. Failure to follow the safeguards and instructions may result in personal injury and/or property damage. Visit www.pyrexhome.com/product-warranties

Are my Pyrex® glassware and lids dishwasher safe?

YES - Pyrex® glassware and lids are dishwasher safe, making cleanup easy and carefree. In the dishwasher, keep both plastic lids and glassware away from direct heat. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How do I wash my Pyrex® glassware by hand?

Use non-abrasive cleansers. To remove baked-on foods, soak the dish and use a plastic or nylon cleaning pad if scouring is needed. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I use my Pyrex® dish to microwave popcorn or heat foods in browning wrappers?

NO - Do not use Pyrex® glassware to microwave popcorn or heat foods in browning wrappers. Microwavable popcorn bags and browning wrappers are specially designed to concentrate heat in targeted areas and may damage the glass. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can my Pyrex® dish go directly from the refrigerator or freezer to the oven or microwave?

Although it is perfectly fine to take your Pyrex® glass dish from the refrigerator and put it directly into a completely preheated conventional or convection oven, we advise allowing your frozen dish to thaw completely before placing it in a completely preheated conventional or convection oven. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I use my Pyrex® measuring cup to melt wax?

NO - Pyrex® measuring cups are intended for food preparation and cooking only and have not been tested for this application. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I heat an empty Pyrex® dish in the microwave to warm or sterilize it?

NO - DO NOT heat a tiny amount of food or an empty dish in the microwave. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

Can I heat butter or oil in my Pyrex® dish?

NO - DO NOT overheat fats such as butter or oil and follow the recommended times for your microwave. Refer to your microwave owner's manual or use and care for foods and timing. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.

How do I remove a stain from my plastic cover?

We cannot guarantee that you will be able to completely remove a stain. Soak the lid in a mixture of water and vinegar and/or try to use a non-abrasive cleanser to lighten stains.

How can I prevent stains on my plastic covers?

To prevent staining, we recommend not filling the dish to the rim/top. Leaving about 2cm gap will allow room for foods to expand when cooled or frozen, thus preventing them from coming in to contact with the plastic cover. Adding a layer of plastic wrap or baking paper before placing the plastic cover, can also help protect the plastic cover.
