Is Pyrex Microwave Safe? (Complete Safety Guide)

Is Pyrex Microwave Safe? People search on Google whether Pyrex is microwave safe. The simple answer is Yes; Pyrex cookware, bakeware, and tableware are microwave safe. Because Pyrex is made with borosilicate glass, known for high heat resistance and entirely different from regular glasses, that’s why Pyrex is microwave safe.

What is Pyrex

Pyrex is the name of glass. The main difference between Pyrex and regular glass is Pyrex is made of borosilicate glass which withstands high temperatures and thermal shock resistance. Regular glass doesn’t withstand high temperatures and can break at sudden temperature changes.

The Corning Glass Works company first introduced Pyrex in the early 1900s, and it has since become a popular material for kitchenware, such as baking dishes, mixing bowls, and measuring cups.

Which products are made of Pyrex

Pyrex is a popular material used to manufacture various kitchenware and laboratory products. Below is a list of products that are commonly made from Pyrex:

Cookware and bakeware items

  • Casseroles dishes
  • Measuring cups
  • Mixing bowls
  • Pie plates
  • Roasting pans Food storage containers
  • Snapware airtight food containers
  • Dry food containers

Beverage products

  • Carafes and decanters
  • Teapots

Microwavable products

  • Microwave-safe bowls

Laboratory glassware

  • Test tubes

Why is Pyrex different from regular glass?

Pyrex is a unique type of glass called borosilicate glass. Several properties make it different from regular glass:

  1. Temperature resistance: Pyrex can withstand sudden changes in temperature without breaking or shattering, making it ideal for use in baking and cooking.
  2. Durability: Pyrex is less likely to break from impact than regular glass due to its increased strength.
  3. Non-reactivity: Unlike regular glass, Pyrex does not react with any foods stored within it, reducing the chances of food or chemical contamination.
  4. Size stability under heat: Pyrex experiences meagre thermal expansion, unlike regular glass, which maintains its shape even when subjected to extreme temperature changes.
  5. Transparency: While both materials are explicit, Pyrex often appears slightly less transparent, which can matter for specific visual purposes.
  6. Weight: Borosilicate glass is slightly lighter and less dense than regular glass, making Pyrex slightly lighter than its counterparts.
  7. Price: Pyrex products are typically more expensive than regular glass due to their enhanced properties.
  8. Microwave Safe: Pyrex glassware is generally microwave-safe, making it a popular choice for reheating and cooking.

Uses of Pyrex products

Pyrex products are used for baking, cooking, storage, mixing, and serving. Pyrex is also widely used in scientific research and laboratory applications, where its thermal stability and chemical resistance make it a valuable material for test tubes, beakers, and other equipment.

Safe And Unsafe Aspects of Pyrex

Every material has safe and unsafe aspects. See the safe and unsafe of Pyrex below.

Safe Aspects

  1. Made with borosilicate glass which is food safe.
  2. Oven safe up to 450 degrees Fahrenheit.
  3. Pyrex® glassware and lids are dishwashers safe.
  4. Microwave safe.
  5. Safe for food storage.
  6. Didn’t react with any foods.
  7. Safe in the Freezer.
  8. Scratch resistant.
  9. Thermal shock resistant.
  10. Safe at the high temperature.

Unsafe Aspects

  • While Pyrex glass is scratch-resistant, deep scratches or chips can create weak points, leading to breakage.
  • Pyrex glass is more robust than regular glass but not shatter-resistant. It can still break when subjected to a strong impact or dropped from a height.

Is Pyrex Microwave Safe? What about microwave oven?

Pyrex is generally safe to use in the microwave oven. Pyrex glassware can handle extreme temperature changes, making it ideal for use in the microwave. However, remember a few things to ensure that your Pyrex dish does not crack or break in the microwave.

Firstly, make sure that your Pyrex dish is microwave safe. Most Pyrex glassware is microwave safe, but there are some exceptions. Look for a label or stamp on the bottom of the dish that indicates it is safe for use in the microwave.

Secondly, never heat an empty Pyrex dish in the microwave. The sudden temperature change could cause the glass to crack or shatter. Always add food or liquid to the dish before microwaving.

Thirdly, avoid placing a Pyrex dish that is extremely cold or frozen directly into the microwave. Gradually increase the temperature of the dish by letting it sit at room temperature for a few minutes before microwaving.

Lastly, handle hot Pyrex dishes with care. Use oven mitts or a towel to remove the dish from the microwave, and place it on a heat-resistant surface to cool.

Is Pyrex dishwasher safe?

Yes, Pyrex is dishwasher-safe. However, if your Pyrex dishes have stubborn food stains or odors, consider hand washing them instead of using the dishwasher. Also, load your Pyrex dishes carefully in the dishwasher so they don’t shift or bump against other dishes during the wash cycle.

Is Pyrex crack or break at high temperature

No, while Pyrex is generally heat resistant, there are limits to how much heat it can handle. Pyrex glassware can safely withstand temperatures up to 450°F (230°C). This means it is safe in the oven, but you should avoid exposing it to direct heat sources, such as the stovetop or broiler.

Can you bake on the Pyrex?

Yes, Pyrex glassware can be used for baking various foods, including casseroles, cakes, and bread. Pyrex dishes are made of glass that is heat resistant, so they can be safely used in the oven to bake.

When using Pyrex for baking, it is essential to follow a few guidelines to ensure that the dish does not crack or break:

  1. Always preheat the oven before placing the Pyrex dish inside.
  2. Do not place the Pyrex dish directly on a hot surface, such as a stovetop, as this can cause thermal shock and lead to cracking or breaking.
  3. Use oven mitts or pot holders when handling the hot Pyrex dish.
  4. Avoid Pyrex dishes with scratches or cracks, as these can weaken the glass and make it more susceptible to breaking.

Can you microwave Pyrex bowls?

Yes, you can microwave Pyrex bowls safely. Do not cover the bowl with a tight-fitting lid. Instead, use a microwave-safe cover or a loose-fitting microwave-safe plate. Heat the food in the Pyrex bowl gradually, using a lower power setting if possible. This helps to prevent the bowl from overheating.

Some Alternatives of Pyrex

Anchor Hocking: This brand offers a range of oven-safe bakeware made with tempered glass.

Duralex: Known for its high-quality tempered glass products, Duralex is a popular choice among chefs and home cooks.

Libbey Glass: Similar to Anchor Hocking, Libbey Glass produces a variety of oven-safe glass bakeware options.

Are Pyrex and Corningware the same?

No, Pyrex and Corningware are not the same. They both are made by the same company, Corning Incorporated, but use different materials for different purposes.

Pyrex is primarily made from borosilicate or soda lime glass. It is famous for mixing bowls and bakeware because it is heat-resistant and can withstand sudden temperature changes.

Corningware is made from a ceramic material called the vitrified glass-ceramic, which has excellent heat-retaining properties and is suitable for use in the oven and on the stovetop.

Summary of key points

Pyrex glassware is a type of glass used for kitchen applications and laboratories.

It was invented by Corning Inc. in the early 1900s and is made from borosilicate glass.

Pyrex glassware is known for its durability, resistance to thermal shock, and transparency.

It can store, measure, and heat substances in laboratories and kitchens.

Available in various sizes, including beakers, test tubes, flasks, and baking dishes.
